Answer:
The answer would be 5h+45
Step-by-step explanation
5 (h+9)
You need to convert this equation into the equation 
you multiply 5 by h and get 5h
Then multiply the same number outside the parenthesis, 5, by 9 which will give you the answer 45
Once you have 5h and 45 just put it together with the addition symbol which will will equal:
5 (h+9) = 5h + 45

Answer:
 (x) =
(x) = 
Step-by-step explanation:
let y = f(x), then rearrange making x the subject
y =  x + 4 ( subtract 4 from both sides )
x + 4 ( subtract 4 from both sides )
y - 4 =  x ( multiply both sides by 5 to clear the fraction )
x ( multiply both sides by 5 to clear the fraction )
5y - 20 = x
Change y back into terms of x with x =  (x) , then
 (x) , then
 (x) = 5x - 20
 (x) = 5x - 20

Answer:
Step-by-step explanation:
We know for a function:
y = Asinωt
=> on comparison, <u>A = 5 m</u>
=> T = 2π / ω
=> T = 2π / 2
=> <u>T = π seconds</u>
