8 0

The solution is 10x² + 7x - 1

Step-by-step explanation:

  • Step 1: Subtract -2x² + 3x - 9 from 8x² + 10x - 10

(8x² + 10x - 10) - (-2x² + 3x - 9) = 8x² + 10x - 10 + 2x² - 3x + 9

                                                 = 10x² + 7x - 1

Naily [24]

Answer:

y=3x+5

every month it would go up by 3 cm so we have 3 and x is to represent the # of months.

You have to subtract both sides by 64 and you will get,
-50 = 5z. Then divide both sides by 5, and you get -10 = z.
