Answer:

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

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

$1.5k-4=-0.5k+8$

$1.5k+0.5k=8+4$

$2k=12$

$k=6$

therefore

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

Yes. It is a wise financial decision because lots of places can be up to 1,000 a month. You would be taking 1,000 out of your check. Giving you only $1,000 for grocerys, car payment, insurence, etc. Only paying $500 can lead to you having more money for other thing. Maybe you wanna go out with your friends, ok? You are spending $1,000 on your apartment and don't have the money, as to where if you are only spending $500, you would have the money to go out and have fun. So, it is a very wise financial decision.

Hope this helped!
