#2. bring the fraction: a / a−4 to a denominator of 16−a^2

Part A: Term is used to bring denominator of

Part B: Term is used to bring denominator of

Explanation:

Part A: To bring the fraction to a denominator of , we need to multiply the denominator by the term

The term is determined by which equals

Thus, the fraction becomes

Thus, the term is used to bring denominator of

Part B: To bring the fraction to a denominator of , we need to multiply the denominator by

Thus, we have,

Thus, the term is used to bring denominator of

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
