Answer:
f(x)=x/7
Step-by-step explanation:
f(x)=7x
y=7x
x=7y (switch y and x for inverse)
x=7y (isolate y)
x/7=y
The inverse of f(x)=7x is f(x)=x/7
(5x) / (2/11) = 3 / (1/5)
cross multiply
(5x)(1/5) = (2/11)(3)
x = 6/11
Answer:
6 books per month
Step-by-step explanation:
choose some points on the graph.
(0, 2)
(1, 6)
(2, 12)
books per month is basically change in y over the change in x or slope
12-6 divided by 2-1
6/1 = 6
