Please help I only have 20 minutes to do this

So basically you just need to graph the two equations.

Step-by-step explanation:

First graph y>=x+1.

- The y intersept is 1. So plot (0,1)

- Then the slope is x or 1x meaing the line is positive. So you would want to plot a point such as (1,1) or (2,2)

- Then make the line

- The since y is greater than or equal to x+1 you would shade the right side of the line.

Do the same with the next equation, y>=4-x

- The y intersept is 4 so plot (0,4)

- The slope is -x, or -1x so the line is negative, so plot a point such as (-1,1) or (-2,2)

- Then make the line

- Shade the right side

1.30

step-by-step explanation:

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
