Question

2 The model represents an inequality.KEYOOOOロロロロロロロロロロロAlSXDOO000OWhat is the solution set for the inequality?FX2-3G x 3H x 20JX2 -16

Answer 1

Each straight bar represents the positive variable x

.And there are 8 straight bars which mean that the variable has a coefficient of 8 like this

$=8x$

In the question on the left-hand side, there are 12 unshaded small squares which indicate a positive number

$=+12$

on The right-hand side, there are also 12 unshaded squares which also indicate a positive number

$=+12$

The general inequality for the model will be

$8x+12\ge12$

By solving the value of x we will resolve the inequality as

$\begin{gathered} 8x+12\ge12 \\ 8x\ge12-12 \\ 8x\ge0 \\ \frac{8x}{8}\ge\frac{0}{8} \\ x\ge0 \end{gathered}$

Therefore, the final answer is OPTION H
