Answer:
y=3x+12
y-12=3x
x=y/3 - 4
f(y)=y/3 - 4
or
f(x)=x/3 - 4
where f(x) is the inverse of y.

Answer:
A
Step-by-step explanation:
Because, the first point will be plotted at 2.5 (each line is 1 which means like line after 0 is 1, the next one is 2, and so one). When you add 2.5 with 4.5 it equals to 7 which means the next point will be placed at 7. (right behind 8)
Surface area of sphere=100pi cm^2
4pi×r^2=100 pi
pi cancel on both sides
4×r^2=100
r^2=100/4
r^2=25
so r=5
So option b 5 cm is correct.
The correct answer is x = 20
