Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ - 7, - 1 ]
f(b) = f(- 1) = (- 1)² + 2(- 1) - 8 = 1 - 2 - 8 = - 9
f(a) = f(- 7) = (- 7)² + 2(- 7) - 8 = 49 - 14 - 8 = 27
Hence
average rate of change = 
= 
= - 6
Answer:
yes it is.
x = 4 and y = -3
Step-by-step explanation:
Solve simultaneously using elimination method:
equation 1 - equation 2
3x + y = 9 equation 1
-2x + y = 5 equation 2
_________
x = 4
plug 4 into any of the 2 equations and solve for y.
3(4) + y = 9
12 + y = 9
12-12 + y = 9-12
y = -3
m = 5a
m + a = 30
Because we already know the value of m, we can find the value of a.
5a + a = 30
<em><u>Combine like terms.</u></em>
6a = 30
<em><u>Divide both sides by 6</u></em>
a = 5
Now that we know the value of a, we can find the true value of m.
m = 5a
m = 5 * 5
m = 25
