Question

Which equation shows the relationship in the table?

A) y = 15x
B) y = 30x
C) y = x + 15
D) y = 15/x

Answer 1

Answer is A

This is because the goal is to find out what number times the time(h) will equal the charge. So for example:

2 x 15 = 30 The 15 is from the first possible answer. You need to plug in each number to see if they match.

Another way to find this out is to divide 30 by 15 which will = 2

The missing value in the table would be 75 because 5 x 15 is 72

Hope this helps :)

Answer 2

A) y=15x hope this helps!!
