Question

Evaluate . | 6a |- 10 for a = - 7

Answer 1

32

Explanation:

| 6a | - 10, when a = -7, looks like | 6(-7) |- 10.

Must multiply 6(-7) first; the correct result is -42.

Then subtract 10, obtaining | -42 | - 10.

Evaluating | -42 |, we get 42 - 10

which is 32

Answer 2

The answer would be 32. This is because once you input -7 you multiply -7 and 6 and end up with -42 but since it is in absolute value it turns into positive 42. Now it is 42 - 10. At this point all you do is subtract which will get you 32. Hope this helps ; )
