Answer:

Step-by-step explanation

Since we are reflecting across the x axis, all of the y coordinates will remain the same. You find the distance away from the x = 4, double it, and add that value to x. So,

X' is now (8,3)

Y' is now (6,0)

Z' is now (4,2) because its x was 0, and anything * 0 = 0 so it does not move.

A neighbor needs to put up a square fence around her garden to keep the deer out. If the area is 500 square feet, how much fence

Maurinko [17]

Let's say side length is s.
s*s = 500, so s = √500.

4 sides needed, total length thus 4*s.

4√500 ≈ 89.4

equation in slope-intercept form is:

$y=9x+7$

Step-by-step explanation:

The general form of slope-intercept form is:

$y=mx+b$

where m is the slope and b is the y-intercept

In the question we are given slope m=9 and a point(0,7)

We will find b i.e y-intercept

$y=mx+b\\7=9(0)+b\\7=0+b\\b=7$

So, value of b=7 and value of slope m=9

So, equation in slope-intercept form is:

$y=9x+7$
