6k < 100
Check all that are true.

k = 5

k = 15

k = 10

k = 20

All of the answers are true except k = 20

Step-by-step explanation:

5, 10, and 15

Step-by-step explanation:

You can plug in every value into the equation:

6 * 5 = 30 < 100

6 * 15 = 90 < 100

6 * 10 = 60 < 100

6 * 20 = 120 >100

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
