“Each set below has 3 expressions. There is ONE expression in EACH set that DOES NOT BELONG. Try to find the expression that does not belong in EACH SET and EXPLAIN WHY!” -please help im behind because I was online schooled at a bad school so now I’m at a different school and my tutor is sick. Set 1: 3(x + 2) 3x +6 3(2x)

Set 2: 1/2 (-4x) 1/2 (2x - 6) x - 3

Set 3: 24x + 8y 2 (12x + 4y) 8(3x + y)

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.

What is the reflection image of (5,-3) across the line y = -x?
