In the equation

, a is the initial amount and b is the growth factor. So our initial amount is 30 and our growth factor is 8.3. Your correct choice for this is A.
Multiply both sides by 30
30(15/18) = y
we then multiply 30*15 = 450
450/18 = y
we then get
y = 25
Answer:
A. y = 1x + 4
B. 1
C. 4
Step-by-step explanation:
The point (0, 4) is the y-intercept. So b = 4
y goes up each time by 1. So m = 1
Plug into y = mx + b
y = 1x + 4
Answer:
Step-by-step explanation:
Answer:
88
Step-by-step explanation:
(17 * 11 = 187) + (9 * -11 = -99)
187 - 99 = 88
