Answer:
z = 3
Step-by-step explanation:
Since the points are collinear then the slopes between the points are equal.
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = P (2, - 3) and (x₂, y₂ ) = Q (3, - 2)
m = 
= 1
Repeat with
(x₁, y₁ ) = Q (3, - 2) and (x₂, y₂ ) = R (8, z )
m = 
= 
, then
= 1 ( multiply both sides by 5 )
z + 2 = 5 ( subtract 2 from both sides )
z = 3
Collinear points are two or more points that lie on the same line.
I believe the answer to that problem would be $68.55, since you have to add them together and then multiply them by .07 for the percentage.
Answer:
y > 2
Step-by-step explanation:
1) 
Divide both sides by <em>3</em>.
2) 
Move the constant to the right side and change it's sign.
3) 
Subtract the numbers.
4)
