**Answer:**

**Step-by-step explanation:**

y = 2x - 3

y = -x

-x = 2x - 3

-x - 2x = -3

-3x = -3

x = -3/-3

x = 1

y = -x

y = -1

solution is : (1,-1) <==

**Answer:**

i think the answer is 99 im not completely sure though

**but i hope this helps **

Answer: y = -2x + 4

Step-by-step explanation:

If you are finding the perimeter the answer would be:

$15.50

If you do 9*$1.75=$15.75

If you do 10*$1.75=17.50

When you find perimeter it’s length+length+ width+ width

This gives you $15.50

If you are finding the area the answer would be:

$157.50

To find area you do 10*9=90

Then, you do 90*$1.75=$157.50
