Answer:

(-1,2)

Step-by-step explanation:

To find the solution, we need to substitute in the points into the equation

5x-2y = -9

(1,-3)

5(1) -2(-3) = -9

5 +6=-9

11 =-9

This is not true so this is not a solution

5x-2y = -9

(2,-4)

5(2) -2(-4) = -9

10 +8 = -9

18 =-9

This is not true so this is not a solution

5x-2y = -9

(-1,2)

5(-1) -2(2) = -9

-5 -4 = -9

-9=-9

This is true so this is a solution

5x-2y = -9

(-2,5)

5(-2) -2(5) = -9

-10-10 = -9

-20=-9

This is not true so this is not a solution

These two polygons are similar.

Jet001 [13]

Answer:

$\huge\boxed{z=3}$

Step-by-step explanation:

If two polygons are similar, then corresponding sides are in proportion.

The corresponding sides:

4 → x

y → 15

3 → w

2 → 6

z → 9

therefore:

$\dfrac{z}{9}=\dfrac{2}{6}$ <em>cross multiply</em>

$(z)(6)=(9)(2)$

$6z=18$ <em>divide both sides by 6</em>

$z=3$
