Answer:
1 ÷ 2(9 + x)
4.5 + 0.5x
Step-by-step explanation:
Given that
We write the expression i.e. half of the sum of $9 and a number
Here we need to write the two expression that is different from each other
So,
Let us assume the number be x.
Now The first equation depend on the information given will be:
= 1 ÷ 2(9 + x)
And, The second equation is
= (9 + x) ÷ 2
= 4.5 + 0.5x
Answer:
c.likely
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
The radius is 1/2 of the diameter
r = 1/2 d
r = 1/2(4) = 2 inches
The circumference is given by
C = 2 * pi * r
C = 2 * pi * 2
C = 4 pi inches
Using 3.14 as an approximation for pi
C = 12.56 inches
The appropriate selection is ...
D. x

This is the purpose and meaning of an inverse function. Using inverse functions is the way we solve equations involving functions. They "undo" the effect of the function.
