Let the number of rows be = r
Let the number of seats per row be = s
we know that the number of seats is 126.
So, ..... (1)
As given, there are five more seats per row than the number of rows, so we can say that:
Putting this in equation (1)
r=-14 and r=9 (neglecting the negative value) we get r=9
And s=r+5
so, s =9+5=14
Hence, there are 5 rows and 14 seats per row.
Answer:
B
Step-by-step explanation:
let f(x) = y and rearrange making x the subject
y = ( multiply both sides by 7 to clear the fraction )
7y = x + 2 ( subtract 2 from both sides )
7y - 2 = x
Change y back into terms of x with x the inverse function, that is
p(x) = 7x - 2
