Answer:
Then the solution set is all the values of x equal to or larger than -3.
Step-by-step explanation:
First, we know that each long strip represents an x.
Each white square represents 1.
Each grey square represents -1
Then, at the left side, we have:
8 long stripes.
12 white squares
Then we can write that as:
8*x + 12*1 ≥
And in the right side, we have 12 grey squares, then that is:
≥ 12*-1 = -12
Then the inequality is:
8*x + 12 ≥ -12
To find the solution set, we just need to isolate x.
First, we can subtract 12 in both sides to get:
8*x + 12 - 12 ≥ -12 - 12
8*x ≥ -24
Now we can divide both sides by 8
8*x/8 ≥ -24/8
x ≥ -3
Then the solution set is all the values of x equal to or larger than -3.
