It should be B because if class average will increase then the cost of books will be increased. Therefore, class average will be independent variable and cost of books will be dependant.

Hope this helps you out... :)

Because the diameter is 47 cm

so the radius is 2x

r = 94 cm

A = πr² / 2

A = (3.14) (94)² / 2

A = 13872.52 cm²

Find the coordinates of the image of Z(−3,−1) after the translation (x,y)→(x−2,y−7).

polet [3.4K]

<h3>Answer: (-5, -8)</h3>

======================================================

Explanation:

We get this point by doing two things.

Subtract 2 from the x coordinate, due to the x-2
Subtract 7 from the y coordinate, because of the y-7

If we started with x = -3, then x-2 = -3-2 = -5. Also, if we had y = -1 then y-7 = -1-7 = -8

So that's how we end up with Z(-3,-1) moving to Z ' (-5, -8)

You could also show your work like this

$(x,y) \to (x-2, y-7)\\\\(-3,-1) \to (-3-2, -1-7)\\\\(-3,-1) \to (-5, -8)\\\\$
