Answer:
Step-by-step explanation:
Factor the equation 
using formula for difference of the cubes:
then
1. The equation 
has real solution 
2. The equation 
has negative discriminant 
then it has two complex solutions
2y = 12 - 5x
y = 6 - 5/2x
2 = -5/2(-3) + b
2 = 15/2 + b
2 - 15/2 = b
b = -11/2
y = 15/2x - 11/2
Answer:
34.06=20+0.19m
Step-by-step explanation:
The 20 dollars is a one-time thing so we don't need a variable for that. The 0.19 per mile does because the cost will depend on how many miles you drove (I used the variable 'm' but you could use a different letter). Altogether the bill costs 34.06 so that will go on the opposite side of our equal side.
34.06=20+0.19m
First we need to isolate 0.19m to find the number of miles the customer drove, and we can do that by subtracting 20 on each side.
34.06-20=20-20+0.19m
14.06=0.19m
Now we divide 0.19 because 0.19 is multiplied to m and division is the opposite operation
m=74
This means that the customer drove 74 miles.
