-x^2 + 4x + 12 = -3x + 24
-> x^2 - 7x + 12 = 0
-> (x-3)(x-4) = 0
-> x= 3 or 4
so y = 15 when x = 3, y = 12 when x = 4
Answer:
Slope= 0.20
Y-intercept=12.50
Equation= Y=0.20+12.50
Step-by-step explanation:
The y-intercept represents the flat charge to hire the plumber
Explanation: The y-intercept is 0 hour, which can represent flat charge
