The slopes and the y-intercepts of two equations are different.
How to calculate the slope-intercept form of the equation?Mathematically, the slope-intercept form of a line can be calculated by using this equation:
y = mx + c
Where:
m represents the slope.x and y are the points.c represents the y-intercept.How to determine the slopes and y–intercepts of the two equations?From the information provided, we have the following equations:
2x + y = 3 ....equation 1.
−2y = 14 − 6x ....equation 2.
In slope-intercept form, the first equation can be written by subtracting 2x from both sides as follows:
2x + y - 2x = 3 - 2x
y = 3 - 2x
y = -2x + 3
Therefore, m = -2 and c = 3.
For the second equation, we would divide both sides by -2 as follows:
−2y/-2 = 14/-2 − 6x/-2
y = -7 + 3x
y = 3x - 7
Therefore, m = 3 and c = -7.
In this context, we can reasonably and logically deduce that the slopes and the y-intercepts are quite different.

Our class is studying the effects of mindfulness on mental health. To help with data collection, we will have the support of ten grade 9, eleven grade 10, twelve grade 11 and thirteen grade 12 students. Showing your calculations,how many different groups of 12 volunteers can we make if:
a) the group must have the same number of students from each grade?
b) the group must have at least two grade 9 students? [2A]
c) the group must have James and Lucy (both grade 11 students) in it? [2A]
The number of groups, using the combination formula, for each case, is given as follows:
a) Same number of students from each grade: 1,245,816,000
b) At least two grade nine students: 31,650,886,995.
c) James and Lucy are in it: 2,481,256,778.
What is the combination formula?[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, obtained by the following formula, involving factorials.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
For item a, the groups are taken as follows:
3 students from grade 9, from a set of 10.3 students from grade 10, from a set of 11.3 students from grade 11, from a set of 12.3 students from grade 12, from a set of 13.Hence the number of groups is:
[tex]C_{10,3}C_{11,3}C_{12,3}C_{13,3} = \frac{10!}{7!3!} \times \frac{11!}{8!3!} \times \frac{12!}{9!3!} \times \frac{13!}{10!3!} = 120 \times 165 \times 220 \times 286 = 1,245,816,000[/tex]
For item b, the total number of groups, without considering the restriction, is:
[tex]C_{46,12} = \frac{46!}{12!34!} = 38,910,617,655[/tex]
The number of groups with none students from grade 9 is:
[tex]C_{36,12} = \frac{36!}{12!24!} = 1,251,677,700[/tex]
The number of groups with one student from grade 9 is:
[tex]C_{10,1}C_{36,11} = 10 \times \frac{36!}{11!25!} = 6,008,052,960[/tex]
Using complementary events, the number of groups with at least two grade 9 students is:
38,910,617,655 - (1,251,677,700 + 6,008,052,960) = 31,650,886,995.
For item c, considering Jamie and Lucy in it, the remaining 10 students are taken from a set of 44, hence:

The amount of money in the account after 10 years will be $42113.64.
What is compound interest?Compound interest is applicable when there will be a change in the principle amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.
As per the given,
Principle amount P = $18000
Rate of interest r = 8.5% = 0.085
Time t = 10
By continuous compounding interest formula,
P = (18000)[tex]e^{0.085\times10}[/tex]
P = $42113.64
Hence "The amount of money in the account after 10 years will be $42113.64".

A young executive is going to purchase a vacation property for investment purposes. She needs to borrow $81,000.00 for 27 years at 6.8% compounded monthly, and will make monthly payments of $546.61. (Round all answers to 2 decimal places) What is the unpaid balance after 12 months? During this period, how much interest did she pay?
1. The unpaid balance after 12 months of paying $546.61 for borrowing $81,000 for 27 years at 6.8% is $79,915.29.
2. During this period, the interest she paid was $5,474.61.
How is the unpaid balance determined?The total payment made, including interest and principal, for 12 months is the product of the monthly payments and 12 months.
From the amortization schedule from an online finance calculator at month 12, we can deduce that the loan balance is $79,915.29.
When this balance is subtracted from the loan, the difference is the principal repayment so far.
N (# of periods) = 324 months (27 years x 12)
I/Y (Interest per year) = 6.8%
PV (Present Value) = $81,000
PMT (Periodic Payment) = $-546.61
Results:
Sum of all periodic payments = $-6,559.32 ($546.61 x 12)
Total Interest for six months = $5,474.61

Part A
A model car is for sale online. Beginning on day one, the owner discounts the price by 5% each day until it sells. On the third day the car sells.
If the original price of the model car was $40, how much did the car sell for to the nearest cent?
Part B
What percent discount does this represent from the original price? Round to the nearest whole percent.
The car was sold for 3429.5 cents and the percent discount from the original price is 14.265%.
According to the question,
We have the following information:
Beginning on day one, the owner discounts the price by 5% each day until it sells. On the third day the car sells. And the original price of the model car was $40.
The first day:
40*5/100
200/100
2
The price on the first day = $38
The second day:
38*5/100
190/100
1.9
The price on the second day = 38-1.9
The price on second day = 36.1
The third day:
36.1*5/100
180.5/100
1.805
The price on third day = $34.295 (36.1-1.805)
1 dollar = 100 cents
Price of car in cents = 3429.5 cents
B) Percent discount from the original price:
Let's take it to be x.
40 - (40x/100) = 34.295
-40x/100 = 34.295-40
-40x/100 = -5.705
40x = 570.5
x = 570.5/40
x = 14.265%
Hence, the car was sold for 3429.5 cents and the percent discount from the original price is 14.265%.

Ken, Mike, and Ariel are eating out at their favorite restaurant. They each order a sandwich combo and plan to split the bill evenly. The service they receive at the restaurant is amazing, so they decide to leave a 30% tip. Their bill total is $50.88 before tax. If Florida’s sales tax is 6%, how much will each person pay? Round your answer to the nearest hundredth.
Each individual paid the sum of $23.4 including state tax at the restaurant
PercentageIn mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%".
In the problem, their total bill is $50.88 and they gave a 30% tip
We should fid 30% of 50.88
0.3 * 50.88 = $15.264
30% of $50.88 is $15.264
If we add this up and then find the state tax to it.
15.264 + 50.88 = 66.144.
Find 6% of 66.144 to determine the state tax.
0.06 * 66.144 = 3.96864
The total amount spent is 66.144 + 3.96864 = 70.11264
We can divide this equally amongst the three people to get the individual payment = 70.11264/3 = 23.37088
Rounding this to the nearest cent, we have 23.4.
We can say each person paid $23.4 at the end of the day

[tex]\sf PMT=\dfrac{Pi\left(1+i\right)^n}{\left(1+i\right)^n-1}[/tex]
where:
PMT = Monthly payment.P = Loan amount.i = Interest rate per month (in decimal form).n = Term of the loan (in months).Given:
P = $12,000i = 0.0498/12 = 0.00415n = 5 years = 60 monthsSubstitute the values into the formula to calculate the monthly payment:
[tex]\implies \sf PMT=\dfrac{12000(0.00415)\left(1+0.00415\right)^{60}}{\left(1+0.00415\right)^{60}-1}[/tex]
[tex]\implies \sf PMT=\dfrac{49.8\left(1.00415\right)^{60}}{\left(1.00415\right)^{60}-1}[/tex]
[tex]\implies \sf PMT=\dfrac{63.84764727}{0.2820812705}[/tex]
[tex]\implies \sf PMT=226.3448656[/tex]
Therefore, the total payments over the life of the loan is the monthly payment multiplied by the total number of months:
[tex]\implies \sf 226.3448656 \times 60=\$13580.69[/tex]
To calculate how much interest Jessie pays over the life of the loan, subtract the original loan amount from the total payments amount:
[tex]\implies 13580.69-12000=\$1580.69[/tex]
Therefore, the interest Jessie will pay over the life of the loan is $1580.69.
Find the equation (in slope-intercept form) of the line passing through the points with the given coordinates.
(−2,3) , (−3,2)
The equation (in slope-intercept form) of the line passing through the points with the given coordinates (−2,3) , (−3,2) is y = x + 5
How to find equation of a line in slope intercept form?The equation of a line in slope intercept form can be represented as follows:
y = mx + b
where
m = slope of the lineb = y-interceptHence, let's find the slope of the line using the coordinates (-2, 3) and (-3, 2).
Therefore,
m = 2 - 3 / -3 + 2
m = - 1 / -1
m = 1
Therefore, lets find the y-intercept using (-2, 3)
y = x + b
3 = -2 + b
b = 3 + 2
b = 5
Hence, the equation of the line in slope intercept form is y = x + 5

Probability
Probability refers the possible way of getting the required event.
Given,
A standard deck of cards has 52 cards of four different suits (diamonds, spades, hearts, clubs). Each suit consists of numbered cards 1 (Ace) to 10, followed by Jack, Queen and King (face cards).
Here we need to find the probability of getting not a face card and we have to round off the resulting value to the tenth percent.
We know that,
Total number of cards = 52
Number of suits = 4
Number of cards in each suit = 13
Number of face cards in each suit = 3
Therefore, the total number of face cards in the deck is calculated s,
=> 3 x 4
=> 12
Therefore, the probability of getting not a face card is
=> (52 - 12)/52
=> 40/52
When we simplify this one then we get,
=> 0.7692
When we convert this into percent and round of to the nearest tenth then we get the probability of getting not a face card is
=> 76.9%.

A pilot is flying over the ocean. She determines that the angles of depression to two ships are 74° and 48°, as shown in the figure below. The plane is 5 miles
from the ship located at point A. How far apart are the ships? Round your answer to the nearest tenth of a mile.
According to the given depression angle, ship is 4.4 miles apart from ship B.
Depression angle:
Depression angle refer an angle that is formed with the horizontal line if the line of sight is downward from the horizontal line.
Given,
A pilot is flying over the ocean. She determines that the angles of depression to two ships are 74° and 48°, as shown in the figure below. The plane is 5 miles from the ship located at point A.
Here we need to find the distance between the two ships.
Here we know the following,
Distance between plane and Ship A = 5 miles.
And the depression angle = 74°, 48°
Let us consider the following, that they sit on a line,
So under this situations,
=> 80 - 48 - 74 = 58 degrees.
The next thing we have to do is bring this 74 degree angle inside the diagram. Because it is congruent to this interior angle because they are alternate.
Then it can be written as,
=> x = sin 74°/5
=> x = 4.4
Therefore, the two ships are 4.4 miles apart from each other.
