Step-by-step explanation:
The solution set of the inequality −5 < 2x + 3 < 9 is (-4,3)
<h3>How to solve the inequality?</h3>
The compound inequality is given as:
−5 < 2x + 3 < 9
Expand the inequality
−5 < 2x + 3 or 2x + 3 < 9
Rewrite as:
2x + 3 > -5 or 2x + 3 < 9
Subtract 3 from both sides
2x > -8 or 2x < 6
Divide both sides by 2
x > -4 or x < 3
Rewrite as:
(-4,3)
Hence, the solution set of the inequality is (-4,3)

Let M represent the cost of a whiteboard marker.
10(3M + $2.75) = $177.50
3M + $2.75 = $17.75
3M = $15
M = $5
Hence, each whiteboard marker cost $5.
The y intercept is what the y value is when x is 0.
Set X to 0 and solve:
-2/9(0) + 1/3
0 + 1/3 = 1/3
The y-intercept is 1/3
