point slope form
y-y1 = m(x-x1)
y- (-2) = 1/3 (x- -9) check y+2 = 1/3(x+9) y+2 = 1/3x +3
point (-2,-9) slope 1/3
Answer:
379.56 ft
Step-by-step explanation:
25 squared = 625
diameter of the half circle is 25
Diameter divided by 2 is radius
pi r squared is the formula for area of circle
r=12.5
pi * 12.5 squared
Given the initial information, we can set up equations. The equation for Clare’s Cleaning Services is:
y = 15x + 20
The equation for Racioppo’s Room Cleaners is:
y = 25x
Let’s substitute 2 in for x:
y = 15(2) + 20
y = 30 + 20
y = 50
y = 25(2)
y = 50
After 2 hours, the cleaning services cost the same.
