The standard form:
The point-slope form:
m - slope
(x₁, y₁) - point
The formula of a slope:
We have the points (2, -3) and (4, 2). Substitute:
<em>use distributive property</em>
<em>multiply both sides by 2</em>
<em>subtract 6 from both sides</em>
<em>subtract 5x from both sides</em>
<em>change the signs</em>
Split it up into 3 separate shapes.
Rectangle 1 = 15 x 3 = 45
Rectangle 2 = 3 x 5 = 15
Triangle = 1/2 x 5 x 3 = 7.5
Total area = 45 + 15 + 7.5 = 67.5 cm²
Answer:
D.
Step-by-step explanation:
You can set up and equation to solve for any cost like so:
5x + 20 = c
5x is the price for each hour
20 is the fixed fee
c is the total cost
Now let's use the price given to solve:
5x + 20 = 50
Subtract 20 from each side:
5x = 30
Divide each side by 5:
x = 6
A vertical line through x = 5
