Gabriel is at the grocery store, and wants to figure out his total cost before he gets to the register. He bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each. Which expressions would represent his total cost? Check all that apply

2.5 x + 2y

Step-by-step explanation:

We know that he bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each.

2.5 pounds of an apple  = x dollars.

2.5 pounds of an apple/cost  = 2.5 x

2 bag of lettuce = y dollar(s).

2 bas lettuce/cost = 2y

Expression: 2.5 x + 2y

Therefore 2.5 x + 2y would represent his total cost.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
