Change in y over change in x is key
(4-1)/(5-6)=3/-1
13. -3
(9-4)/(2-0)=5/2
14. 5/2
(1-(-2))/(-6-4)=3/-10
15. -3/10
Answer:
f[c(p)] = 0.784p
Step-by-step explanation:
sales discount = 30%
sales tax = 12%
c(p) = 0.7p where p is the original price
f(c) = 1.12c where c is the sales price of the bike.
f[c(p)] = 1.12(0.7p)
f[c(p)] = 0.784p Last option.
Assume: p = 100
c(100) = 0.7(100) = 70
f(70) = 1.12(70) = 78.4
f[70(100)] = 0.784(100) = 78.4
Answer:

Step-by-step explanation:
Let the number of months = x
It is given that,
Carson deposits $70 each month and has $450 in his bank account.
So, the initial deposit is $450 and monthly deposit is 40x.
Let Carson's bank balance = y (in dollars).
Thus, the linear function representing the bank balance is,
