Answer:
f(g(x)) = 8x² + 18x - 8
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(- 2x - 1)
= 2(- 2x - 1)² - 5(- 2x - 1) - 15
= 2(4x² + 4x + 1) + 10x + 5 - 15
= 8x² + 8x + 2 + 10x - 10
= 8x² + 18x - 8
Answer:
12
Step-by-step explanation:
6(d+1)−2d=54
Here, we have to find the value of d
multiply (d+1) by 6
6×d + 6×1 - 2 d= 54
6d + 6 - 2d= 54
Now subtract 2 d from 6d
6d- 2d +6= 54
4 d+ 6=54
Now, by using transposition method,
+ 6 will be transferred from L.H.S to -6 to R.H.S
4 d = 54- 6
4d= 48
Now, divide 48 by 4
d= 48÷ 4
d= 12
Hence, the value of d is 12
Hence, the correct answer is 12
Answer:
Option C, x/12
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Which expression represents how many years are in x months?
x/12
<em>Because this will give us the amount of months over 12 which gives us the amount of years.</em>
<em />
<u>Example: Find out how many years are in 30 months</u>
x/12
30/12
<em>2.5 years</em>
