Graph the solution to the inequality:

[tex]\[ -8 \geq -5x + 2 \ \textgreater \ -38 \][/tex]


Sagot :

To solve the inequality [tex]\(-8 \geq -5x + 2 > -38\)[/tex], we will break it into two separate inequalities and solve them step-by-step.

### Step 1: Solve [tex]\(-8 \geq -5x + 2\)[/tex]
1. Subtract 2 from both sides:
[tex]\[ -8 - 2 \geq -5x \][/tex]
[tex]\[ -10 \geq -5x \][/tex]

2. Divide by -5 (note that dividing by a negative number reverses the inequality sign):
[tex]\[ \frac{-10}{-5} \leq x \][/tex]
[tex]\[ 2 \leq x \][/tex]

### Step 2: Solve [tex]\(-5x + 2 > -38\)[/tex]

1. Subtract 2 from both sides:
[tex]\[ -5x + 2 - 2 > -38 - 2 \][/tex]
[tex]\[ -5x > -40 \][/tex]

2. Divide by -5 (remember to reverse the inequality sign):
[tex]\[ \frac{-40}{-5} < x \][/tex]
[tex]\[ 8 < x \][/tex]

### Combine the Results
From Step 1, we have:
[tex]\[ x \geq 2 \][/tex]

From Step 2, we have:
[tex]\[ x > 8 \][/tex]

### Getting the Combined Solution
To satisfy both inequalities, we need to consider the tighter bounds. So, the combined inequality is:
[tex]\[ x > 8 \][/tex]

### Graphing the Solution
To graph the solution [tex]\(x > 8\)[/tex]:

1. Draw a number line.
2. Put an open circle on 8 (to indicate that 8 is not included).
3. Shade the number line to the right of 8 to represent all numbers greater than 8.

The graph looks like this:

[tex]\[ \begin{array}{cccccccc} & & & & & \circ & \rightarrow & \\ \end{array} \][/tex]

This open circle at 8 and the shading to the right indicates [tex]\(x > 8\)[/tex].
