Step-by-step explanation:
If your aboe to do that you can so anything
Answer:
40
Step-by-step explanation:
To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:
C = 2M + 7
(Variables are representative of the first letter of each name)
Seeing as Christopher scored 87, we can put that into the equation and solve for M.
So, the equation will be:
87 = 2M + 7
Subtract 7 from both sides in order to isolate variable M on the right side.
80 = 2M
Now solve for M, which is 40 (divide both sides by 2).
I think the answer is (x-2 ) x ( x+2)
Answer:
Step-by-step explanation:
For this case we must determine the inverse of the following function:

Step 1:
We would write
or 
Step 2:
We clear x:


Step 3:
"x" and "y" are exchanged:

The inverse is:
