Answer:

No

Step-by-step explanation:

To determine if (- 5, - 5) is a solution

Substitute x = - 5 into the inequality and compare answer to y

- 2(- 5) + 4 = 10 + 4 = 14 > - 5 ← the y- coordinate

Thus (- 5, - 5) is not a solution to the inequality

Paul is going to have the exterior of his home painted. Painting USA charges $75.00 to come out and evaluate the house plus $25.
user100 [1]
Given:$75
25 hours

Painting USA : Fixed cost: $75 ; Variable Cost: $25x
Total Cost = 75 + 25(25) = 75 + 625 = 700

Upscale Home Painting: No Fixed Cost ; Variable Cost : $40x
Total Cost = 40(25) = 1,000

The most cost effective company will be Painting USA whose charge will amount to $700.

Write in slope-intercept form an equation of the line that passes through the points (−5,−9) and (5,1).
o-na [289]

Answer:

y=x-4

Step-by-step explanation:

The slope is given by

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

m = (1--9)/(5--5)

m = (1+9)/(5+5)

    = 10/10

   = 1

The slope is 1

We have the slope and a point,so we can use point slope form

y-y1 = m(x-x1)

y-1 = 1(x-5)

y-1 = x-5

Add 1 to each side

y-1+1 = x-5+1

y=x-4

This is slope intercept form (y= mx+b)
