Question

It’s due tonight I would appreciate the help

Answer 1

-1, 4, 6, 8

k<9

Explanation:

Two ways to do this

One is to substitute the values in for k and then see if the inequality is still true.

-1, 4, 6, 8, when substituted in for k and then multiplied by 5, will be less then 45.

9, however, does not work because 9 times 5 is 45, which makes the inequality untrue. So, k has to be less than 9.

The faster, more mathematical way is to divide both sides by 5. 5 divided by 5 is 1 and 45 divided by 5 is 9, so the new inequality would be k<9.

Answer 2

If you divide both sides of your inequality by five, you see that k must be less than 9

k < 9 that is equivalent.

You can make another equivalent inequality by multiplying both sides by 3.

3k < 27
