Question:

Evaluate n(x)=−1−x+4 when x=−2,0, and 5

Answers

Step-by-step explanation:

n(-2) = -1 - (-2) + 4 = -1 + 2 + 4 = -1 + 6 = 5

( - 1 , 6 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [6] is +. So, result is 5)

n(0) = -1 - 0 + 4 = -1 + 4 = 3

n(5) = - 1 - 5 + 4 = -6 + 4 = -2

( -6 , 4 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [-6] is -. So, result is -2)

15 x 66 — 10055 so that’s what I did
