For this case we have a function of the form:
y = A (b) ^ x
Where,
A: initial amount
b: decrease rate
x: time
We have then:
b = 0.15
Therefore the percentage of decrease is:
(1-0.15) * 100 = 75%
Answer:
75%

Step-by-step explanation:
Answer:
SLOPE = -5
Step-by-step explanation:
Because that's what x is.
Answer:
So the x’s are the slopes and the y’are the y intercept. You write an equation by doing y=mx(slope) + b( y intercept. For example number 4, y=1x+5. Do the rest for all of them that will take me forever. Good luck.

Answer:
Step-by-step explanation:
drama+yearbook=64
drama=10 more than yearbook
drama=10+yearbook
the equations are
x+y=64
x=10+y
solve
subsitue 10+y for x
10+y+y=64
10+2y=64
minus 10 both sides
2y=54
divide both sides by 2
y=27
subsitute back
x=10+y
x=10+27
x=37
