Question

circle the correct response.

1. what is the sum of -8 and -12?

a. 20
b. 4
c. - 20
d. - 4

1. which expression is equivalent to

a. 4 + 9
b. 4 - 9
c. - 4 - 9
d. - 4 + 9

1. if x = - 15 and y = 7, find x + y.

a. - 22
b. - 8
c. 22
d. 8

1. which equation correctly shows -7 to -1 by subtracting a number

Explanation:

Step1: Calculate sum for question 1

$-8+( - 12)=-8 - 12=-20$

Step2: Analyze options for question 2

No full - question provided for 2, assume we are comparing expressions in general arithmetic. But without a target expression, we can't solve precisely. For the sake of showing arithmetic operations, $4 + 9=13$, $4-9=-5$, $-4 - 9=-13$, $-4 + 9 = 5$.

Step3: Calculate sum for question 3

Given $x=-15$ and $y = 7$, then $x + y=-15+7=-8$

Answer:

1. C. - 20
2. (Incomplete question)
3. B. - 8
