Answer:
The bus must be used 21 times a month so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book.
Step-by-step explanation:
This problem can be modeled by two first order functions. One function is the monthly cost without the coupon book, and the other function is the monthly cost with the coupon book.
Monthly cost without the coupon book:
The only thing that the person will spend is the bus fare, that is $1.75. So the cost is:
where n is the number of times that the person rode the bus.
Monthly cost with the coupon book:
The person will spend $21 for the book plus the bus fare, that will be $.75. So the cost is:
The total monthly cost without the coupon book is the same as the total monthly cost with the coupon book when C1 = C2. So:
The bus must be used 21 times a month so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book.
Answer:
64° and 116°
Step-by-step explanation:
Supplementary angles sum to 180°
let one angle be x then the other is 2x - 12 ( 12 less than twice the other )
Sum the 2 angles and equate to 180
x + 2x - 12 = 180
3x - 12 = 180 ( add 12 to both sides )
3x = 192 ( divide both sides by 3 )
x = 64
The 2 angles are x = 64° and 2x - 12 = (2 × 64) - 12 = 128 - 12 = 116°
Answer:
Step-by-step explanation:
a) y=
x=-1 ⇒ y=
x=1 ⇒ y=
x=2 ⇒ y=
x=4 ⇒ y=
b) =
so the blue one
12 im guessing if its true like if not delete pz
