Answer:

This is a compression by a factor of 3 in the x direction

(horizontal compression by factor of 3)

This reflects it about the x axis

Step-by-step explanation:

f(x)=|x|

h(x) = |3x|

This is a compression by a factor of 3 in the x direction

g(x) =-|3x|

This reflects it about the x axis

Hong rented a truck for one day. There was a base fee of $20.95, and there was an additional charge of 90 cents for each mile dr

Goryan [66]

Answer: Hong drove the truck for 294 miles.

Step-by-step explanation:

Let m represent the number of miles for which he drove the truck.

There was a base fee of $20.95, and there was an additional charge of 90 cents for each mile driven. It means that the expression for the cost of driving the truck for m miles in a day is

20.95 + 0.9m

Hong had to pay $285.55 when he returned the truck. It means that

20.95 + 0.9m = 285.55

0.9m = 285.55 - 20.95

0.9m = 264.6

m = 264.6/0.9

m = 294 miles

An art club is going to a museum. Six adults are going. 18 more kids than adults are going. Adults tickets cost $24 each, which

dybincka [34]

so their are 6 adults and 24 kids because when you add 18+6 and get 24

then you multiply 6(24) because adult tickets are 24 and get 144

then you multiply 24(12) because student tickets are half as much as parents so they are 12 and you multiply by 24 kids and get 288

then you add 288 student tickets total price +144 adult ticket total price =432 total cost fro all tickets
