Answer:
a. 2x + 4
Step-by-step explanation:
Four more than twice a number
Let x = unknown number
Four more than twice of x
Twice of x can be written as 2x
Four more than 2x
Four more can be written as + 4
We get 2x + 4
Answer:
Not possible
Step-by-step explanation:
The notation (f °g)(-2) means f(g(-2)). You will substitute -2 into g(x) then substitute the value or equation that results into f(x).
g(-2) = √x - 16 = √-2 - 16
This is not possible because the value of -2 cannot be found in a square root. Square roots do not compute real roots for negative numbers.
Answer:
34
Step-by-step explanation:
|2 - 4a| - 2(b - 7)
|2 - 4(3)| - 2(-5 - 7)
|2 - 12| + 10 + 14
|-10| + 10 + 14
10 + 10 + 14
20 + 14
34
Best of Luck!
