Answer:
x=6
Step-by-step explanation:
First, add x to each side.
72=-2x+84
Subtract 84 from each side
-12=-2x
Dive each side by -2
6=x
-7 is losing the fewest as it is the smallest number, and the number that is to the left of the number line.
(-x²-2x+6)+(-9x²-7x+6) = -x²-2x+6-9x²-7x+6 = -10x² - 9x + 12
McNeary gets payed annually about;
45.67 x 52 = 2374
24.63 x 52 = 1280
19.04 x 52 = 990
In total this adds up to 4644 dollars.
