Question

What is the value of -216x - y when x = -3 and y = 4?
044
O -28
O 28
O 44

Answer 1

- 44

Explanation:

The absolute value function always gives a positive result, that is

| - a | = | a | = a

Given

- 2 | 6x - y | ← substitute x = - 3 and y = 4

= - 2 | 6(- 3) - 4 |

= - 2 | - 18 - 4 |

= - 2 × 22

= - 44
