Answer:
(x) = 2x + 12
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
y = x - 6 ( multiply through by 2 to clear the fraction )
2y = x - 12 ( add 12 to both sides )
2y + 12 = x
change y back into terms of x with x = (x) , then
(x) = 2x + 12
4 and 48 are the factors because they are what are added together to get the answer.
Hope this helps.
Answer:
- 1
Step-by-step explanation:
The average rate of change in the closed interval [ a, b ] is
Here [ a, b ] = [4, 7 ], thus
f(b) = f(7) = 7² - 4(7) - 1 = 49 - 28 - 1 = 20
f(a) = f(- 4) = (- 4)² - 4(- 4) - 1 = 16 + 16 - 1 = 31
average rate of change = = = - 1
Answer:
4/32 = x/40
160 = 32x
x = 5

create a ratio, cross multiply, solve
0.34%
Another way to get a percent, is to move the decimal two places to the right. (Even if your percentage still looks like a decimal, it is still a percent.)
