Sheila has 12 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each week of which hold 1 3/4 pounds. How many container does she need?

Sheila needs 8 containers.

Step-by-step explanation:

so first you start with 12 1/2 pounds of potato salad, which can also be expressed by 12.5

next you want to divide it into 1 3/4 pound containers, which can be expressed by 1.75.

so we have 12.5/1.75

this equals about 7.14

since there is excess potato salad we have to round our answer up for 8 containers to fit all of Sheilas potato salad.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
