20 points Please help me match the equation with the method ty
Answer:
a. Substitution method.
b. Elimination method.
c. Graph method.
Step-by-step explanation:
Given the following algebraic expressions;
a. y = 3x + 10 ....... equation 1
2x - 4y = -6 ...... equation 2
The above would be solved using substitution method.
Substituting eqn 1 into eqn 2, we have;
2x - 4(3x + 10) = -6
2x - 12x - 40 = -6
-10x = -6 + 40
-10x = 34
x = 34/10
x = 3.4
y = 3x + 10 = 3*3.4 + 10
y = 10.2 + 10 = 20.2
b. 9x + 2y = 29 ...... equation 1
3x - 2y = -17 ...... equation 2
The above would be solved using elimination method.
Adding eqn 1 to eqn 2, we have;
(9x + 3x) + (2y + (-2y)) = (29 + (-17))
12x + 0 = 12
12x = 12
x = 12/12 = 1
To find y, from eqn 1;
9(1) + 2y = 29
2y = 29 - 9
2y = 20
y = 20/2 = 10
c. y = 3/2x - 5
y = 2x + 8
The above would be solved using a graph method.
You choose a range for the value of y and x. These values are then plotted against each other and the slope of the graph is determined.

Find the value of x :)
Answer:
x = 20
Step-by-step explanation:
→ Remember how many degrees are on a straight line
180°
→ Set up an equation
2x + 70 + 3x + 10 = 180
→ Simplify
5x + 80 = 180
→ Minus 80 from both sides
5x = 100
→ Divide both sides by 5
x = 20
Answer:
x=20
Step-by-step explanation:
Those add up to 180 degrees because a straight line is 180 degrees
Equation
2x + 70 + 3x + 10 = 180
Add liked terms
2x+3x=5x
5x+80=180
5x+80-80=180-80
Divide both sides by 5
5x=100
x=20
hope this helps and good luck! <3
Factor out the greatest common factor from 4x2−36x
Answer:
4x
Step-by-step explanation:
Given the expression
4x² - 36x
Get the individual factor of each terms
4x² = 4 * x * x
36x = 4 * 9 * x
4x² - 36x = 4x(x-9)
From both factors we can see that 4*x is common to them, hence the greatest common factor is 4x

The solution
[tex]1 + \sqrt{4x + 5} = 5[/tex]
Collect like terms
[tex]\sqrt{4x + 5} = 5 - 1[/tex]

Square both sides
[tex]4x + 5 = 16[/tex]
Collect like terms
[tex]4x = 11[/tex]
Divide both sides by 4
[tex]x = 11/4[/tex]
If p and q vary inversely and p is 22 when q is 17, determine q when p is equal to 187
Answer:
Q=2
Step-by-step explanation:
p=k/q
When P=22, q=17
22=k/17
k=374
When p =187
187=374/q
187q=374
q=2
The value of q when the value of p is 187 will be equal to 2
What is the constant of proportionality?Two numerical sequences, often experimental data, are said to be proportional or directly proportional if their corresponding elements have a constant ratio, which is known as the coefficient of proportionality or proportionality constant.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that p and q vary inversely and p is 22 when q is 17, The
p=k/q
Calculate the value of k when P=22, q=17,
22=k/17
k=374
Calculate the value of q when p =187,
187=374/q
187q=374
q=2

Mingfa says, "My sister and I have $130 altogether. If my mother gives me another
$10, I'll have 3 times as much money as my sister."
How much money does Mingfa actually have?
Given:
Total amount of Mingfa and her sister = $130
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
To find:
How much money does Mingfa actually have?
Solution:
Let, Mingfa have $x and her sister has $y initially. Then,
[tex]x+y=130[/tex] ...(i)
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
[tex]x+10=3y[/tex] ...(ii)
Substitute the value of x from (ii) in (i).
[tex](3y-10)+y=130[/tex]
[tex]4y=130+10[/tex]
[tex]4y=140[/tex]
Divide both sides by 4.
[tex]y=35[/tex]
Putting [tex]y=35[/tex] in (i), we get
[tex]x+35=130[/tex]
[tex]x=130-35[/tex]
[tex]x=95[/tex]
Therefore, Mingfa have $95.

Jeremy homeowners policy has a face value of 56,400 and a 750 deductible. How much will the insurance pay on a a 1,612 loss
Answer: 862
Step-by-step explanation:
A deductible refers to the amount of money that one will have to pay himself or herself toward an insured loss.
It should be noted that when a disaster occurs, the amount of the deductible will be subtracted from the loss. Since the loss is 1612 and the deductible is 750, the insurance company will pay:
= 1612 - 750
= 862

How many three digit numbers can you get by arranging the numbers 5, 6,
7, 8, 3, 4, 5, 6, 7, 8, 9?
Answer:
84 numbers
Step-by-step explanation:
Numbers starting with 12 – 7 numbers
Numbers starting with 13 – 6 numbers;
14 – 5, 15 – 4, 16 – 3, 17 – 2, 18 – 1.
Thus total number of
numbers starting from 1 is given by the sum of 1 to 7 = 28.
Number of numbers starting from 2- would be given by the sum of 1 to 6 = 21
Number of numbers starting from 3- sum of 1 to 5 = 15
Number of numbers starting from 4 – sum of 1 to 4 = 10
Number of numbers starting from 5 – sum of 1 to 3 = 6
Number of numbers starting from 6 = 1 + 2 = 3
Number of numbers starting from 7 = 1
Thus a total of: 28 + 21 + 15 + 10 + 6 + 3 + 1 = 84 such numbers.

Covert both sides to the same units.Compare the number of feet of fence he bought with the number of feet of fence he needsThe perimeter of the rectangular fence is 42 feets.
Properties of a rectangle.Opposite sides are equal.Opposite sides are parallel.The angles are right angle.
Therefore, two sides of the garden are 12 feet each long. The other two sides are 108 inches long.
The steps to take to make sure he bought enough fence is as follows:
Covert both sides to the same units.Compare the number of feet of fence he bought with the number of feet of fence he needs.Therefore,
108 inches = 9 ft
Therefore,
12 + 12 + 9 + 9 = 42 feet's.
He bought 40 feet fence. Therefore, he needs 42 feet's of fence which means the fencing will not be enough.
