Mine is pretty rough but hope it helps look at the attached image.
Answer:
22.5 deg
Step-by-step explanation:
Step-by-step explanation:
the function actually is
y = 40(x - 1) + 70 = 40x - 40 + 70 = 40x + 30
still, the slope (the factor of x) is 40.
that means y (the cost) increases by 40 for every additional hour (x increases by 1).
so, the rate of change (slope) is 40/1 = $40 per hour.
I think you mean "what is the QUOTIENT?"




when x= -4 ,f(x)=2
Step-by-step explanation:
the coordinate in which f(x) i.e y=2 is (-4,2)
thus x= -4
