The solution set for the inequality −3x+1≤−47 can be graphed as a number line.

To graph the inequality, we need to isolate x on one side of the equation. First, we subtract 1 from both sides:

−3x+1−1≤−47−1
−3x≤−48

Next, we divide both sides by -3 (remembering to reverse the inequality sign when dividing by a negative number):

−3x/−3≥−48/−3
x≥16

On the number line, we can shade the region to the right of 16 to represent the solution set. Including the endpoint 16, the graph would look like this:

```
-∞ ◻=====================◼ 16 +∞
Not shaded Shaded
```

The shaded portion of the number line represents the solution set for the inequality.

Apologies for the previous response. Here is a simpler representation of the solution set for the inequality −3x+1≤−47:

To graph the inequality, isolate x by subtracting 1 from both sides of the equation:

−3x+1≤−47 - 1
−3x≤−48

Next, divide both sides by -3 (remember to flip the inequality sign when dividing by a negative number):

x ≥ -48 ÷ -3
x ≥ 16

The solution set is represented by all numbers greater than or equal to 16 on the number line:

```
-∞ ---------------------●═════════════════════════► +∞
Not shaded Shaded
```

The shaded portion represents the solution set, which includes the endpoint at x = 16.

Equation: 250 - 5m = 30

Solution: Solve the equation for m:

250 - 5m = 30

Subtract 250 from both sides:

-5m = 30 - 250

-5m = -220

Divide both sides by -5:

m = 44
