To solve the inequality 7n + 1 > 169, we can first subtract 1 from both sides:
7n > 168
Next, we divide both sides of the inequality by 7:
n > 24
Therefore, the solution to the inequality is n > 24.
Now let's graph the solution on a number line. We start by marking a point at 24 and shading to the right to represent numbers greater than 24.
Number line:
<-----|-------------------]
-∞ 24 ∞
The shaded part of the number line represents the solution to the inequality n > 24.
Solve and graph the solution for this inequality.

is it a closed or open circle?
Apologies for any confusion in my previous response. The correct graph for the inequality 7n + 1 > 169 is an open circle at 24, since the inequality is strictly greater than 24.
Here is the corrected number line representation:
<-----o------------------->
-∞ 24 ∞
The open circle at 24 indicates that 24 is not included in the solution set.
Here is the corrected number line representation:
<-----o------------------->
-∞ 24 ∞
The open circle at 24 indicates that 24 is not included in the solution set.
shade left or right?
Apologies for the confusion once again. The correct shading for the solution to the inequality 7n + 1 > 169 is to the left, not to the right as stated in my previous response.
Here is the corrected number line representation with the shading to the left:
<-----|-------------------o
-∞ 24 ∞
The shaded part of the number line represents the solution to the inequality n > 24.
Here is the corrected number line representation with the shading to the left:
<-----|-------------------o

Solve and graph the solution for this inequality.
-3x + 5 ≤ 23
-3x + 5 ≤ 23
To solve the inequality -3x + 5 ≤ 23, we can start by subtracting 5 from both sides:
-3x ≤ 18
Next, we divide both sides of the inequality by -3. Since we are dividing by a negative number, we must flip the inequality symbol:
x ≥ -6
Therefore, the solution to the inequality is x ≥ -6.
Now let's graph the solution on a number line. We start by marking a closed circle at -6 and shading to the right to represent numbers greater than or equal to -6.
Number line:
<----------o----------------]
-∞ -6 ∞
The closed circle at -6 indicates that -6 is included in the solution set. The shaded part of the number line represents the solution to the inequality x ≥ -6.
-3x ≤ 18
Next, we divide both sides of the inequality by -3. Since we are dividing by a negative number, we must flip the inequality symbol:
x ≥ -6
Therefore, the solution to the inequality is x ≥ -6.
Now let's graph the solution on a number line. We start by marking a closed circle at -6 and shading to the right to represent numbers greater than or equal to -6.
Number line:
<----------o----------------]
-∞ -6 ∞
The closed circle at -6 indicates that -6 is included in the solution set. The shaded part of the number line represents the solution to the inequality x ≥ -6.
