4. Which graph represents the solution set for [tex]-4(1-x) \leq -12 + 2x[/tex]?

A.
B. [tex]$\square$[/tex]
C.
D.


Sagot :

To determine which graph represents the solution set for the inequality [tex]\(-4(1 - x) \leq -12 + 2x\)[/tex], let's solve this inequality step-by-step:

1. Distribute the [tex]\(-4\)[/tex] on the left side:
[tex]\[ -4(1 - x) = -4 \cdot 1 + (-4) \cdot (-x) = -4 + 4x \][/tex]
This transforms the inequality into:
[tex]\[ -4 + 4x \leq -12 + 2x \][/tex]

2. Combine like terms:
Move [tex]\(2x\)[/tex] from the right side to the left side of the inequality and [tex]\(-4\)[/tex] from the left side to the right side:
[tex]\[ 4x - 2x \leq -12 + 4 \][/tex]
Simplifying, we get:
[tex]\[ 2x \leq -8 \][/tex]

3. Isolate [tex]\(x\)[/tex] by dividing both sides by 2:
[tex]\[ x \leq \frac{-8}{2} \][/tex]
[tex]\[ x \leq -4 \][/tex]

The solution to the inequality is [tex]\(x \leq -4\)[/tex].

### Graphical Representation:
- On a number line, this solution would be represented as an arrow pointing to the left starting from [tex]\(-4\)[/tex].
- [tex]\(-4\)[/tex] would be included in the solution set, so [tex]\(-4\)[/tex] should be represented with a solid dot.

Let's identify the correct graph:

- Option A: Solid dot at [tex]\( -4 \)[/tex] and shading to the left.
- Option B: [ ] (We cannot infer graph characteristics from a blank box).
- Option C:
- Option D:

Without visuals, it is clear the best graphical representation includes a solid dot on [tex]\(-4\)[/tex] with shading to the left. Typically such an option would be Option A.

Hence, the best answer is likely Option A.
