Answer:
x = t(a+p)/4
Step-by-step explanation
Given the expression
a=4x/t - p
We are to make x the subject of the formula
a=4x/t - p
Add p to both sides
a+p = 4x/t - p+p
a+p = 4x/t
Cross multiply
t(a+p) = 4x
Rearrange
4x = t(a+p)
Divide both sides by 4
4x/4 = t(a+p)/4
x = t(a+p)/4
f(x) = {(1,3), (1,5), (1,7), (1,9)}
Domain = 1, 1, 1, 1
Range = 3, 5, 7, 9
Divide the number of words she types (162) by 3 mins = 54 words in 1 minute
