Answer:
Rate of change = -12
Step-by-step explanation:
y − 3 = −12(x + 4)
Expanding, we have;
y - 3 = -12x - 48
y = -12x - 48 + 3
y = -12x - 45
Now, formula for rate of change is;
Rate of change = (y(x + h) - y)/h
y(x + h) is; y = -12(x + h) - 45
This gives;
Rate of change = (-12(x + h) - 45 + 12x + 45)/h
Rate of change = (-12x - 12h - 45 + 12x + 45)/h
Rate of change = -12h/h
Rate of change = -12

The attached shows the two plots. The break-even points are near
x = 21
x = 256
4 hours and 15 minutes =4+15/60=4.25 hours
the average speed of the train = 250/4.25=58.82mph
Answer:
I think that the answer is 19.
Step-by-step explanation:
Writing out the problem
x²+yz
Substituting the given values of the variables
(-3)²+(5)(2)
Simplifying (-3)², which is 9
9+(5)(2)
5 times 2 equals 10
9+10
19
I hope this helped you. Enjoy your day, and take care :)
