Solve the equation replacing x with 2 and the 6:
-2^2 + 2(2) + 2 = 4 + 4 + 2 =10
-6^2 + 2(6) + 2 = 36 + 12 + 2 = 50
Difference between the answers: 50-10 = 40
Difference between 2 and 6 = 6-2 = 4
Average rate of change = 40/4 = 10
The answer is 10

Answer:
-27
Step-by-step explanation:
5(x+3) = 4(x-3)
5x + 15 = 4x - 12
5x - 4x = -12 - 15
X = -27
Answer:
Step-by-step explanation:
Put hypotheses as:

(Two tailed test at 4%)
Since population std deviation is given we can do Z test.

Test statistic t = mean diff/se = 
p value=0.075
Since p >0.04 our alpha, we accept null hypothesis.
At alphaequals0.04, we cannot reject the company's claim
