Answer:
Explanation:
I'm assuming that you need to pick the correct solution set using the given inequality. Let's solve this much like we would an equation, ubt taking into account that the sign shown is a less than sign. This implies that the dot over whatever x is less than is not filled in. So forget a and c since those dots are filled in. Let's see which one, b or d, is the answer we need.
5x + 28 < 13 and
5x < 13 - 28 and
5x < -15 so
x < -3. The choice you're looking for is d. Each line on that graph represents 3 units.
