= 16 + 8
= 24
Step-by-step explanation:
6|8-y|-15
6|8-10|-15
6|-2|-15
6(2)-15
12-15
-3
Answer:
its 8 cause 2 times x is 40 40+-40= 0 so 2 times 4 is 8
Step-by-step explanation:
Answer:
y + 2 = (x - 2)
Step-by-step explanation:
From the graph, you can see that when y = 0, x = 2, and vise versa. Taking this into consideration, if y = 4, x = 2, so, the answer is y + 2 = (x - 2)
