For this case we have the following functions:

By definition of composition of functions we have:

Then substituting:

So:

Answer:

Answer:
4
Step-by-step explanation:
3 + 4(2x - 1) = 23
4(2x - 1) = 20
8x - 4 = 20
8x = 24
x = 3
---------
2(3) - 2
6 - 2
4
Answer:
59
Step-by-step explanation:
alternate interior angles are congruent
We need to evaluate the value of fraction
.
We also given j=12.
In order to evaluate the value of fraction
, we need to plug j=12.
Plugging j=12, we get

We have 12 in numerator and 4 in denominator.
We always divide top number by bottom number.
So, we need to divide 12 by 4.
On dividing 12 by 4 we get 3.
<h3>Therefore,

</h3>
