Hi,
.
for example:
x > -8
Ask yourself: Which of these numbers a. 0 b. -8 c. -7 d. 7 is > -8
c. and d
.
x-6 > 0 or x >6
Ask yourself: Which of these numbers a. 0 b. 6 c. -6 d. 5 1s > 6
none
.
8x < 24 or x< 3
Which of these numbers a. 3 b. -3 c. 0 d. 8 is < 3
b. and c.
.
-8x > 24 or x < 3 (multiplying or dividing by neg number changes the direction of the inequality)
Which of these numbers a. 3 b. -3 c. 0 d. 8 is < 3
b. and c.
.
-8x < -24 or x > 3 (Note: direction of inequality changed dividing by neg number
Which of these numbers a. 3 b. -3 c. 0 d. 8 is > 3
d.
