Answer 1

Answer: Choice F)
`x \le -5`

====================================================

Step-by-step explanation:

One long rectangle represents x. Four of them represent 4x

One tiny unshaded square represents a unit 1. Specifically this value is positive. We have 2 columns and 6 rows, so there are 2*6 = 12 tiny squares.

So the stuff in the first box (the four long rectangles and the 12 tiny unshaded squares) represent the expression 4x+12

The stuff in the second box is -8 since we have 8 shaded squares each shaded square being -1.

----------------

The inequality we need to solve is
`4x+12 \le -8`

We'll subtract 12 from both sides, then divide both sides by 4 to fully isolate x

This is what the steps would look like:

`4x+12 \le -8\\\\\\4x+12-12 \le -8-12 \ \text{ subtract 12 from both sides}\\\\\\4x \le -20\\\\\\(4x)/(4) \le (-20)/(4) \ \text{ Divide both sides by 4}\\\\\\x \le -5\\\\\\`

The inequality sign does not flip since we did not divide both sides by a negative number.
