The question linked to the chart: Write the linear function in slope-intercept form only that corresponds with this table. Please help!
Answers
A linear function in slope-intercept form that only corresponds with this table is y = 2x + 8.
How to write the linear function in slope-intercept form?Mathematically, the slope-intercept form of a straight line is given by;
y = mx + b
Where:
x and y represents the points.m represents the slope.b represents the y-intercept.Mathematically, the slope of any straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
From the information provided, we have the following parameters:
Point (x, y) = (-1, 6)
Point (x, y) = (0, 8)
Substituting the given points into the formula, we have;
Slope, m = (8 - 6)/(0 - (-1))
Slope, m = (2)/(0 + 1)
Slope, m = 2/1
Slope, m = 2.
In Mathematics, the y-intercept of a graph occurs at the point where the x-value is equal to zero (0), which is 8 in the table shown above.
Therefore, the slope-intercept form is given by:
y = mx + b
y = 2x + 8

What is the percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of agcl when treated with excess ag⁺? report your answer to two decimal places.
Answers
The percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of AgCl when treated with excess ag⁺ is 17.2%
The percent of chloride can be calculate as follow:
Mass of AgCl precipitated = 1.750 g
Molar mass of AgCl = 143.32 g/mol
Molar mass of Chlorine atom = 35.45 g/mol
Asume, all the chlorine in the sample is precipitated to silver chloride. So, the mass of chlorine in silver chloride will be equal to the mass of chlorine present in the sample.
To calculate the mass of chlorine in given mass of AgCl, we apply unitary method:
In 143.32 g of silver chloride, mass of chlorine present is 35.45 g
So, in 1.3487 g of silver chloride, mass of chlorine present will be =
35.45g/143.32 g * 1.750 g = 0.43 g
To calculate the percentage composition of chlorine in pure chloride compound, as follows:
Mass of pure chloride compound = 2.500 g
Mass of chlorine = 0.43 g
% Chlorine = 0.43/2.5 *100
% Chlorine = 17.2 %
Therefore, the mass percentage of chloride in pure chloride compound is 17.2%

The given expression 7x - y = -9 in the slope intercept form can be represented as y = 7x + 9.
The expression given to us is -
7x - y = -9
We have to represent this in the slope intercept form.
The slope intercept form can be represented as -
y = mx + c
where, y = y coordinate of the line
m = slope of the line
x = x coordinate of the line
c = y intercept of the line
Thus, representing the given expression in the slope intercept form, we have
7x - y = -9
=> -y = -7x - 9
=> y = 7x + 9
Thus, the given expression in the slope intercept form can be represented as y = 7x + 9.

To raise money for after-school programs at an elementary school, a group of parents is holding a weekend of games in a community center. They charge $8 per person for entry into the event. The group would like to earn at least $600, after paying for the cost of renting the space, which is $40 an hour.
Answers
The inequality represents the situation group of parents who would like to earn at least $600, after paying for the cost of renting the space $40 an hour, and charging $8 per person for entry into the event is 8x - 4y ≥ 600, and x > 0, Y > 0.
We are given the following;
They charge $8 per person for entry into the event.
The group would like to earn at least $600, after paying for the cost of renting the space, which is $40 an hour.
Let the number of people be x and the number of hours they are present in the space be y.
Per person entry cost is $8.
Donations by all the people entering the space are 8x.
The per hour cost of rent is $40.
The total cost of renting the space is 40y which will be subtracted from the total amount of donations.
They plan to earn a minimum of $600.
So, the inequality will be given by;
8x - 4y ≥ 600 and x > 0, Y > 0.
Thus, the inequality represents the situation group of parents who would like to earn at least $600, after paying for the cost of renting the space $40 an hour, and charging $8 per person for entry into the event is 8x - 4y ≥ 600, and x > 0, Y > 0.

The people at a party tried to form teams with the same number of people on each team, but when they tried to split up into teams of 2, 3, 5, or 7, exactly one person was left without a team. What is the smallest number of people (greater than $\color[rgb]{0.35,0.35,0.35}1$) who could have been at the party?
Answers
The smallest number of people when one could have been at the party is 211 people.
How to illustrate the information?This is a least common multiple question, also known as an LCM. We know this because all groups would have formed evenly if the one extra person had not arrived at the party. This means that there are 1 more people at the party than a number 2, 3, 5, or 7.
In this case, the number will be:
= (2 × 3 × 5 × 7) + 1
= 210 + 1
= 211
Applicable multiples of 7
(7 × 10) = 70 → 70 + 1 = 71 → 71/3 = 23 R2 → not possible
(7 × 20) = 140 → 140 + 1 = 141 → 141/3 = 47 → not possible
(7 × 30) = 210 → 210 +1 = 211 → 211/3 = 70 R1 → possible.

b) Describe the correlation of the scatter plot.
c) What will the approximate depth be at 15 seconds?
Answers
Considering the data in the table, it is found that:
a) The scatter plot is given by the image at the end of the answer.
b) The correlation of the scatter plot is negative, as when the input increases the output decreases.
c) The estimate for the depth at 15 seconds is of 50.37 cm.
How to built the scatter plot?The scatter plot is built inserting all the points in the table, which are in the following format:
(Time, Depth).
Hence the points are given as follows:
(2, 47), (4, 41), (6, 38), (8, 37), (10, 32), (12, 24), (14, 20), (16, 19).
From both the table and the scatter plot given by the image at the end of the answer, as the input increases, the output decreases, hence the scatter plot has a negative correlation.
To make a prediction for a given input, the line of best fit has to be constructed using these points.
Inserting these points into a linear regression calculator, the line of best fit is:
y = -2.07x + 50.89.
At a time of 15 seconds = 0.25 minutes, the depth will be of:

The value of x in the isosceles triangle is 9.25.
What is the value of x?An isosceles triangle is a polygon that has three sides. The opposite length have the same length and equal angles. has two opposite sides. If the two angles are equal , it means the triangle is an isosceles.
Th perimeter of an isosceles triangle is the sum of the length of the three sides of the triangle.
Perimeter = (2 x length of leg) + base
43 = (2x x) + 2x - 6
43 = 2x + 2x - 6
43 = 4x - 6
43 - 6 = 4x

Answers
The answer of the given question is $6.4, this is the money that need to be added onto the bill for the tip.
How to calculate a 20% tip?
To calculate tip, we need to multiply the total bill by 1 plus the decimal percentage tip we'd like to leave. If we wanted to leave a 20% tip, we would add 1 to 0.20 to get 1.20. Then, multiply the bill by 1.20 to get the total amount we'd leave including tip.
In this case, we have a $32 bill and we would like to add on an 20% tip. So, it will be as follows:
20% = 0.20
1 + 0.20 = 1.20
Total bill will be 1.20 x $32 = $38.4
Hence, the tip amount is $38.4 - $32 = $6.4

The price of a gallon of milk was $2. 65. The price rose y dollars after the last hurricane. Then the price dropped $0. 15 and later rose again by $0. 5. Which expression represents the current price of milk?.
Answers
The expression represents the current price of milk is 3 + y in dollars
The initial price of a gallon of milk = $2.65
The price rose y dollars after the last hurricane
Then the expression will be
2.65 + y
Then the price dropped $0. 15
2.65 + y - 0.15
Add the terms
2.65 + y - 0.15 = 2.5 - y
later rose again by $0. 5
2.5 + y + 0.5
Add the terms in the expression
2.5 + y + 0.5 = (2.5 + 0.5) + y
= 3 + y
Current price of milk = 3 + y in dollars
