Answer:

-2 (filled in circle) to 7 (open circle)

Explanation:

for the first equation x must be the equal to or smaller than 6. so -3(-2) equals 6 but anything less than -2, let's say -3(-3), will be BIGGER than six, so -2 including -2 which is a filled in circle.

solving it:

-3(x)
\leq 6


(-3x)/(-3) \leq (6)/(-3)


x\leq -2

for the second equation x must be smaller than 17. so first you take out + 3 by subtracting it, leaving the equation as 2x<14. 2(7)<14 is NOT true so anything bigger than 7 leaves it as true because 6.98934747483 can still make it true, so anything smaller than 7 which is 7 with a not filled in, or open, circle

solving it:


2x + 3 (- 3) < 17 (- 3)

2x < 14


(2x)/(2) <(14)/(2)

x < 7

my explanation is all over the place, but hope this helps!!!
