You're using inverse operation to solve this equation. Now you just have to think about it. What number plus 20 would equal the same number squared? The answer would be 5, since
5+20=5^2
25=25
The statement above is true :)
Another number that would work for the equation would be x= -4
-4+20=-4^2
16=16
The statement above is also true so your answer would be x=-4 and 5
9514 1404 393
Answer:
9397
Step-by-step explanation:
The expected number of women is ...
(11.6/50)×40,505 = 9397.16 ≈ 9397

Answer:
f ∘ g(5) = 47
Step-by-step explanation:
We are given the following functions:
Composite function:
The problem asks their composite function at x = 5. So
We have that f ∘ g(5) = 47
Answer:
Let's say that x is sam's age and y is Amy's age
x=y-4
and five years ago:
x-5=(y-5)/2
y-4-5=(y-5)/2
2y-18=y-5
y=13
x=9
then:
sam's age is 9 and Amy's age is 13
Equal f(g(-2))
=f(-8)
= -19
