Answer:
Using the inverse composition rule you know that if (fog)=x and (gof)=x then the functions are inverses.
(

7 this will result in (gof)=x
(

=x
graphically you can check this if it seems that the functions are reflected over the line x=y.
Step-by-step explanation:
So the its basically 7x24 and 7x24 is 168. Hope this helped
From 5 to 100 is 10 (10,20,30,40,50,60,70,80,90,100)
from 110 to 200 is another 10
10+10=20
20 numbers
Answer:
5 and -8
Step-by-step explanation:
One number must be negative since the product of the 2 number is negative (5 x -8 = -40). They both cannot be negative, if they were the product would then be positive. The negative number must have a absolute value that is larger than the positive, the negative numbers distance from 0 must be larger than the positive, -8 has a distance of 8 and 5 has a distance of 5. The sum of the two numbers is
=5 + (-8)
=5 - 8
= -3
