Answer:

x=-4.44

Step-by-step explanation:

3x - 40x + x + 20 = 180

3x - 40x + x + 20 - 20 = 180 - 20   =  

3x - 40x + x = 160

-36x = 160

-36x/-36 = 160/-36

x = -4.44

What is an equation of the line that passes through the points (5,5) and (-5,-7)?
tatyana61 [14]

Answer:

y=6/5x-1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-7-5)/(-5-5)

m=-12/-10

simplify

m=6/5

y-y1=m(x-x1)

y-5=6/5(x-5)

y=6/5x-30/5+5

y=6/5x-6+5

y=6/5x-1
