8-4(x-y)=2x+6

8-4x+4y=2x+6

8-8-4x+4y=2x+6-8

-4x+4y=2x-2

-4x-2x+4y=2x-2x-2

-6x+4y=-2

HOPE THIS HELPS!!!!!!!!

8 - 4 (x - y) = 2x + 6
8 - 4x + 4y = 2x + 6
8 + 4y = 6x + 6
2 + 4y = 6x
2 = 6x - 4y

So, C

A scatter plot is made to model the amount of money left to pay on a credit card. The data used for the scatter plot are shown i

Option d: The original balance on the credit card.

Explanation:

To determine the y-intercept, let us use the formula,

$y=mx+b$ where m is the slope and b is the y-intercept.

Also, $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Let us choose the coordinates $(3,1400)$ and $(5,1000)$

Substituting, we get,

$m=\frac{1000-1400}{5-3} =\frac{-400}{2} =-200$

Thus, the formula becomes

$y=-200x+b$

Now, to determine the value of b, let us substitute $(1,1800)$ in the formula,

we get,

$\begin{aligned}&1800=-200(1)+b\\&2000=b\end{aligned}$

Substituting the value of b in the formula, we have,

$y=-200 x+2000$

Thus, the y-intercept is $b=2000$

At y-intercept the value of x is 0. It means the y-intercept represents the amount of money left to pay on a credit card when the number of months is 0.

Thus, the y-intercept represents the original balance on the credit card.

Hence, Option d is the correct answer.

Rewrite the following equation in slope-intercept form.

Roman55 [17]

The following equation, y − 8 = 15 (x + 5) is in the slope-intercept form and will be y=15x+83.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.

$\rm m =\dfrac{y_2-y_1}{x_2-x_1}$

It is given that the equation is,

y − 8 = 15 (x + 5)

y=15(x+5)+8

y=15x+75+8

y=15x+83

A linear equation has the form y = mx + b in the slope-intercept format.

Thus, the following equation, y − 8 = 15 (x + 5) is in the slope-intercept form and will be y=15x+83.

The floor of a conference hall can be covered completly with tiles.Its length is 36ft. longer than its width.The area of the flo

Masteriza [31]

Answer:

Step-by-step explanation:

Given

Area of a floor = 2040ft²

If Its length is 36ft. longer than its width, then L = W+36

Area = LW

L is the length

W is the width

A < W(W+36)

2040 < W²+36W

0<W²+36W-2040

W²+36W-2040 >0

W = -36±√36²-4(-2040)/2

W = -36±√1296+8160)/2

W = -36±√9456/2

W = -36±97.25/2

W = -36+97.25/2

W = 61.24/2

W > 30.62ft

Since L = W+36

L > 30.62+36

L > 66.62ft

The width of the floor is 30.62ft

The length is 66.62ft

The mathematical sentence would represent the given situation is the width is greater than 30.62ft while the length must be greater than 66.62ft

The possible dimension of the floor is 31ft by 67 ft

The possible areas is 31*67 = 2077ft²

It won't be realistic to get an area of 144sqft because the initial area is greater than 144. Hence the feasible area will be greater than 2040ft²
