a=-s+150

3s-8s+1200=1000

-5s=-200

s=40

The image below, what is true about angles 1, 2, and 3?

ziro4ka [17]

Answer:

C. 2 = 37

Step-by-step explanation:

<2 and 37 are vertical angles and vertical angles are equal

Angle 1 and 37 form a straight line so they add to 180

<1 + 37 = 180

<1 = 180-37 = 143

Angle 3 and 37 form a straight line so they add to 180

<3 + 37 = 180

<3= 180-37 = 143

Find the slope of the line (-3,-2) (1,6)

nlexa [21]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (1, 6)

m = $\frac{6-(-2)}{1-(-3)}$ = $\frac{6+2}{1+3}$ = $\frac{8}{4}$ = 2
