Answer:
#12 is 1
Step-by-step explanation:
12. Table #3
13. Table #4
14. Graph #4
15. Graph #1
12. None of the tables can have repeating x-values
13. Only one with a repeating x-value
14. If you draw a line on any of the graphs you will go through one of the lines on the graph at least twice (Means it's not a function)
15. Only one where you draw a line and it'll go through twice
12
x = k/y Multiply each side by y
k = xy Insert values
= 6 × 72
= 432
x = 432/y Let y = 36
= 432/36
x = 12
The point-slope formula:
We have (-2, 1) and (1, 7).
Substitute:
A and D
-7/2-4= -15/2
-7+1/2(-4)
-7-2
-9
