Find the percent rate of change in these two equations. Round your answers to the nearest tenth. Show your work.
y = ( 1 - 0.221 )^t AND y = 0.5 ( 1 + 1.226 )^t

22.1% decrease

122.6% increase

Step-by-step explanation:

1 - 0.221 is a decrease:

0.221 × 100

= 22.1% decrease

1 + 1.226

1.226 × 100

= 122.6% increase

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times
