Step-by-step explanation:

1) label x1, y1, x2, and y2.

x1 y1 x2 y2

(-12, 16) (-4,-2)

2) Remember the formula is y2-y1

--------

x2-x1

3) substitute

-2-16

--------

-4-(-12)

4) two minuses (negatives) is a positive (+)

so,

-2-16 -18

---------= --------

-4+12 8

Sergio [31]

Let “t” represent the number of minutes Martha exercises each day. If she needs to exercise *at least* 30 minutes, t has to be equal to or greater than 30, so our inequality would be

t ≥ 30

What is the value of x in the solution to this system of equations?

siniylev [52]

Answer:

D) x=9

Step-by-step explanation:

x = 2y- 5

2y = x + 5

y = (x+5) / 2

4x + 7(x+5)/2 = 85

8x + 7x + 35 = 85*2

15x + 35 = 170

15x = 170 - 35 = 135

x = 135/15 = 9
