W = -6
You get the formula from (8, -10) and the slope.
Answer:
x = 2 or
x = -7
Step-by-step explanation:
(x - 2)(x + 7) = 0
x - 2 = 0
Add 2 to both sides
x - 2 + 2 = 2 + 0
x = 2
OR
x + 7 = 0
Subtract 7 from both sides
x + 7 - 7 = 0-7
x = -7
Therefore
x = 2 or
x = -7
Answer: 40
Step-by-step explanation:
The angles form a straight angle, so y = 180 - 80 - 60 = 40.
Answer:
5/9
Step-by-step explanation:
Answer:
Option B. It represents a nonlinear function because its points are not on a straight line.
Step-by-step explanation:
Let

we know that
If point A,B and C are on a straight line
then
The slope of AB must be equal to the slope of AC
The formula to calculate the slope between two points is equal to

<em>Find the slope AB</em>

substitute in the formula

<em>Find the slope AC</em>

substitute in the formula

so

Points A, B and C are not on a straight line
therefore
It represents a nonlinear function because its points are not on a straight line
