Question

(ANSWERS IN THE IMAGE ABOVE)

Select the correct graph that shows the solution to 18 > 3x - 3

Answer 1

c

Explanation:

Solve the inequality, that is

18 > 3x - 3 ( add 3 to both sides )

21 > 3x ( divide both sides by 3 )

7 > x, hence

x < 7

< is denoted by an open circle on the number line at 7, meaning that x cannot be equal to 7. Since less than 7 then the arrow head points to the left of 7
