Answer:
A and C.
Step-by-step explanation:
It says that the a value increases by 2 but that still doesn't change the fact the graph is infinite. So the domain is still the same, and the range is still the same.
Let M = #miles driven
Plan 1: .50M + 70 = total cost
Plan 2 .70M = total cost
To know how far she would drive to have an equal cost for either plan just set the equations equal to each other
.70M = .50M + 70
subtract .50M from both sides
.20M = 70
M = 70/.20 = 350 miles
Check the answser:
Plan 1: .50(350) + 70 = 175 + 70 = $245
Plan 2: .7(350) = $245
they are equal so our answer checks as correct
Answer:
3 & 43/80
Step-by-step explanation:
take 17 and 11/16 and turn it into a mixed number
you will get 283/16
keep, flip, change
so you will keep 283/16, flip the sign so you are multiplying instead of dividing, and then change the 5/1 to a 1/5
then just multiply straight across
you get 283/80
then simplify and get 3 and 43/80
