The answer to this question is 6
Answer:
- A matches with 5.
- B matches with 3.
- C matches with 2.
- D matches with 6.
- E matches with 4.
- F matches with 1.
Step-by-step explanation:
To find the inverse of a function 
, we let 
and then solve again for y.
For example, using 
, we will let 
, giving 
. This means that 
, and thus 
.
Using similar logic, we see that:
- A matches with 5.
- B matches with 3.
- C matches with 2.
- D matches with 6.
- E matches with 4.
- F matches with 1.
Answer: b=2
Step-by-step explanation: First you will have the equation 22=11b. You need to get b by itself so you will need to divide each side by 11 which will leave you with 22/11=11/11b. After that you will be left with 2=b
Step-by-step explanation:
I take it this is meant to be a multiplication, right ?
not a "function of function", which would be symbolized by a little empty circle.
to multiply 2 function means basically the same as to add, subtract or divide 2 functions : to apply the arithmetic operation in both expressions.
(f×g)(x) = (-2x² + 4x)(x² + 18x + 77) =
= -2x⁴ - 36x³ - 154x² + 4x³ + 72x² + 308x =
= -2x⁴ - 32x³ - 82x² + 308x
Answer:
x = 25
Step-by-step explanation:
x = # of hrs he worked at his weekday job
w = # of hours he worked at his weekend job
25+ x = 40y = 40 - 25 = 15.
Therefore, Mia worked for 25 hours at his weekday job and 15 hours at his weekend job.
w + x = 40
20x + 18w = 770
18(x + w = 40) = 18x + 18w = 720
(20x + 18w = 770) - (18x + 18w = 720)
2x=50
x=25
