C) 2:3 and 12:18
bcs you put them in fraction form and cross multiply them
Plug each x-value into the equation to get the y-value:

(2,-1)

(0,-2)
V = 1/3 * 3.14 * 11 * 6^2 = 414.48 m^3
cost = V * 20 = 414.48 * 20 = 8289.60
Answer:
k = 27
Step-by-step explanation:
Answer:
The value of b is -42
Step-by-step explanation:
Parallel equations have identical or equal slopes. Given the form of the equation; y=5x+b and the point it passes through (8,-2) we determine the unknown value b by substituting x with 8 and y with -2. We solve the equation; -2 =5(8)+b to obtain b = -42
