Step-by-step explanation:
Answer:
Step-by-step explanation:
-x - 6 > 21 - 28x
27x - 6 > 21
27x > 27
x > 1
800,000 is the correct answer
Answer:
D
Step-by-step explanation:
let y = f(x), that is
y =
Rearrange making x the subject
Multiply both sides by 5
5y = 2x - 3 ( add 3 to both sides )
5y + 3 = 2x (divide both sides by 2 ) , then
x =
Change y back into term of x, hence
(x) = → D
