Answer:
1.) 8
2.) 23
3.) -7
Step-by-step explanation:
1.) x + 2 = 10 2.) y - 8 = 15 3.) a + 9 = 2
- 2 -2 + 8 +8 - 9 -9
------------------ ------------------- ------------------
x + 0 =8 y - 0 = 23 a + 0 = -7

Perhaps the point of this exercise is to help you understand that the average slope computed by the first expression approaches the instantaneous slope computed by the second expression. This happens when a approaches x and when h approaches zero.
In this problem, where the function is a straight line, the slope is a constant (-3), so the average slope and the instantaneous slope are the same everywhere (for all values of x, a, h).
Answer:
7+4
Step-by-step explanation:
When you are subtracting a negative, you are really adding the number. For example, four minus negative seven is equal to four plus seven.
4 - (-7) = 4+7
4+7 = 7+4 (By the commutive property of addition)

Given expression is x² - 121
This is called Difference of Squared terms, we have a formula that is given as :-
a² - b² = (a - b) · (a + b)
Now using the above formula in the given expression, we get :-
x² - 121
x² - (11)²
here a = x and b = 11
x² - (11)² = (x - 11) · (x + 11)
but it says that student gave the answer as (x - 11) · (x - 11).
So, student's answer should be (x - 11) · (x + 11) instead of product of two (x - 11) terms.
