1. is the equation true, false or open? explain. 8 + 4 = -5 + 7
2. which ordered pair is a solution of the equation y = -11x + 4? make sure you show work! a.
(0,-7) , -7) c, (1, -7) d. (2,26)
3. complete the table and state the rule.

1. False

2. c. (1, -7)

3. Input= 1 and 4; Output=6, 12 and 18. The rule is the input×3

Step-by-step explanation:

1. 8+4=±5+7

8+4= 12 & ±5+7= 2

The left side  12  does not equal to the right side  2 , which means that the given statement is false.  

2. I'm not sure how to show my work.

3.

Input: 0, 1, 2, 3, 4, 5, 6

Output: 0, 3, 6, 9, 12, 15, 18

0×3=0; 1×3=3; 2×3=6; 3×3=9; 4×3=12; 5×3=15; 6×3=18
