Answer:
So the slope is -8/3
Step-by-step explanation:
to find the slope you have to use m = y2-y1/x2-x1
so lets plug in our numbers
m = - 4- 4/5-2
= -8/3
So the slope is -8/3
Answer:
A: 3
Step-by-step explanation:
Hopefully this helps!
A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
