18. At a store, a pack of six turkey burgers costs $5.00. A pack of six buns costs $3.00. One pack of turkey burgers and
one pack of buns serve one table of people at Tessa's barbecue. Iff) = 5x represents the total cost of x packs of
turkey burgers and if g(x) = 3x represents the total cost of x packs of buns, which function can Tessa use to determine
the total cost of servingx tables of people at her barbeque?
A. (x)=f(x) -9(x) B1(x) =F ch(x) = f(s) +g(x) D. (x) = f(x) - g(x)

I would say add it up

Step-by-step explanation:

Step-by-step explanation:

The correct answer would be C - h(x) = f(x) + g(x). The total cost for serving everyone at the barbecue would consist of adding the cost of both the buns and turkey burgers.

it would be 6xy and -16xy.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
