Answer:
20 % decay
Step-by-step explanation:
Exponential equations are in the form
y = a * b^x
a is the initial value
b is the growth or decay
b>1 is growth b-1 rate of growth
b <1 decay 1-b rate of decay
1-.8 = .2
Change to decimal form
20 % decay
5x+15=90
5x= 75
X=15
Because it’s complementary
Answer:
