Answer: y = -5x + 20

Step-by-step explanation:

Remember that : y=mx+b

y = (-5)x + b

Now you can plug your coordinates (-7,8) into that equation.

8 = (-5)-7 + b

Solve for b

8 = -12 + b

Add +12 to both sides of your equation:

20 = b

Now, your new equation is:

y = -5x + 20

Answer:

x=-5/4 or x=9/4

Step-by-step explanation:

-4x = -9

x = 9/4

2 - 4x = 7

-4x = 7-2

-4x = 5

x = -5/4

suppose you have a rectangle with a length 8 cm and width 3 cm. Now suppose the sides are doubled. Find the percent os increase

mr Goodwill [35]

The original perimeter is 22 cm.

If both sides are doubled, the length would be 16 cm and the width would be 6 cm.
The perimeter would be 44 cm.

22/44 is 50%.
