Answer:
Step-by-step explanation:
We can combine the -7x and the -2x and the left side to get -9x and the 23 and 13 on the right side to get 36.
This gives us
-9x + 12 = 36
Subtacting 12 from both sides gives us
-9x = 24
dividing by -9 gives us
x = - 8/3
Answer:
20+2y
Step-by-step explanation:
20 pounds more would be an addition of 20 and twice would have to be represented by 2y because it is double John's weight y.
The results of the composite functions are:
<h3>What are composite functions?</h3>
Composite functions are functions that are obtained by combining two or more functions together
Assume that:
Then the computation of the composite functions are as follows:
<h3>Function (f * g)(x)</h3>
<h3>Function f(g(x))</h3>
We have: 
This gives
So, we have:
<h3>Function g(f(x))</h3>
We have: 
This gives
So, we have:
