Answer:
the average rate of change in y with respect to x over the interval is 7. that is, for every single unit by which x changes, y on average changes by 7 units.

Step-by-step explanation:
This question isn't worded the greatest, there are two ways you can read this.
1. The quotient of a number and -9, increased by 10, is 11
2. The quotient of a number, and -9 increased by 10, is 11
The first equation will look like this

And the second will look like this

So I have solved for both (I personally believe the second way of reading the question is the correct way)
we are given

we have to find theta
so, firstly we can write sin in terms of cos

now, we can set it equal

Since, both sides are cos
so, we can set angles equal

now, we can solve for theta
we get

Answer:
2nd - (w - 5)(w + 5)
4th - (-4v - 9)(-4v + 9)
Step-by-step explanation:
1. The first option shows an expression multiplied by its opposite(x -1), so therefore, it does not show the difference of squares
2. The second option does show the difference of squares because it is in the form (a + b)(a - b)
3. The third option is just a square because the same expression is multiplied by itself.
4. The fourth option is the difference of squares because it is in the form (a + b)(a - b). a equals -4v and b equals 9 in this case.
5. The fifth option is not the difference of squares. No term in common in both expressions
6. The sixth option is just a square because the same expression is multiplied by itself.
In all, there are two options that are the difference of squares, the 2nd and 4th.
