solve the inequality and graph the solution

Question

1/2+ × < 4          <---|------|----|----|----|--->

 

Thank you :)

Answer 1

1/2+ × < 4

to clear fractions, multiply everything by two:

1 + 2x < 8

2x < 7

x < 7/2 i.e. x < 3.5

 

The graph shows a small circle at 3.5 and an arrow from that, pointing to the left.
