The function t(x) = 3x + 5 determines how many cans of corn kernels a food truck needs to stock, where x is the number of shifts
Inessa [10]

Answer: 31


Step-by-step explanation:

Given: The function t(x) = 3x + 5 determines how many cans of corn kernels a food truck needs to stock, where x is the number of shifts the crew is going to work in the truck.

At x=3

t(3)=3(3)+5=14

The crew uses c(t(x)) to find the amount of money to spend on corn. The function c(x) = 2x + 3

When the crew is going to work 3 shifts,the amount of money must be spent

=c(t(x))=c(14)=2(14)+3=28+3=31

The amount of money must be spent when the crew is going to work 3 shifts=31

alisha [4.7K]
2500x0.80=2000 so i think it would be 2000 in 8 years

or if youre adding the 2000 to the already existing 2500 then it would be 4500.

Write the slope-interceptiin form of the equation 17=y+4x
erastova [34]

Answer:

Step-by-step explanation:

slope intercept form is y = mx + b

17 = y + 4x....we have to get y on one side and everything else on the other side.....so the easiest way would be to subtract 4x from both sides

17 - 4x = y + 4x - 4x....combine like terms

17 - 4x = y...rearrange

y = -4x + 17 <===== slope intercept form
