Answer:
(x) =
Step-by-step explanation:
let y = h(x) and rearrange making x the subject, that is
y = x + 12 ( multiply through by 4 to clear the fraction )
4y = 3x + 48 ( subtract 48 from both sides )
4y - 48 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) =
Answer:
312
Step-by-step explanation:
Let the attendance before the drop be x
Now we are given that attendance dropped 4% this year
So new attendance =
=
=
We are also given that attendance dropped 4% this year, to 300
So,
Hence the attendance before the drop was 312
For direct variation:
y = kx
-12 = 9k
k = -12/9 = -4/3
Therefore, the required equation is y = -4/3 x
