For what value(s) of k will the relation not be a function?
a = {(1.5k−4, 7), (−0.5k+8, 15)}

K=6

Step-by-step explanation:

we know that

A function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output

so

In this problem

If the x-coordinate of the first point is equal to the x-coordinate of the second point, then the relation will not be a function

Remember that the x-coordinate is the input value and the y-coordinate is the output value

Equate the x-coordinates and solve for k

therefore

If the value of k is 6 the, the relation will not be a function

k=6

Step-by-step explanation:

1.5k-4=-0.5k+8

8+4=1.5k+0.5k

12=2k

k=6

ok

step-by-step explanation:

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
