purchases * percentage discount = savings
purchases * .32 = 64
divide each side by .32
purchases = 64/.32
purchases = 200
He bought 200 worth of items before his discount
Answer: $200
12-5x+6x=412-5x+6x=4 the answer is going to be
x=-12
12-5(-12)+6(-12)=412-5(-12)+6(-12)=4
The period of the function is that distance where the function becomes equal again.
We have then:
Part 1:
The period of the function is:
T = 3
Part 2:
The period of the function is:
T = 4
Answer:
The period of functions 1 and 2 respectively are:
T = 3
T = 4
