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 answer is 16 I think because 2*2=4*5=20-4=16 so I think 16 is the right answer

Answer:
He must score 83 in the last test.
Step-by-step explanation:
To get a mean of 80 Terry must score a total of 4*80 = 320 over the 4 tests.
So his score for the last test must be 320 - (71 + 80 + 86)
= 320 - 237
= 83.
