**Answer:**

**13 unit**

**Step-by-step explanation:**

By the distance formula,

The distance between two points and is,

Thus,** the distance between B(8,-7) and C(-4,-2)** is,

For part a,

y < x

y > -2x

Point B: (3,1) plugin x=3, y=1 y < x 1 < 3

which is true, so point B satisfies the first inequalityYou can graph the inequality y > 2x+5 and see which schools are in the shaded region

It helps me to convert the fractions into decimals, so 11/15=.73 and -5 1/2= -5.5.

Next, just add -5.5 to .73, you should get -4.77, then convert that back to a fraction and get -4 23/30 :)

I think the answer is Dtell me if I’m wrong
