<u>Answer:</u>
<u>given:</u>
- adjacent side: 10
- hypotenuse side: 20
<u>using cosine rule:</u>
Using it's concept, it is found that the average rate of change of the function from x = -1 to x = 5 is of -1.
<h3>What is the average rate of change of a function?</h3>
It is given by the <u>change in the output divided by the change in the input</u>.
In this problem, the output changes by -6(from 7 to 1) when the input changes by 6(from -1 to 5), hence the average rate is given by:
r = -6/6 = -1.

Answer:
y>=14
Step-by-step explanation:
y is the age, and you must be older than or as old as 14.
Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.
