-5x > 0
-5x/-5 > 0/-5
x < 0 since we are dividing by a negative, the inequality changes
so, no the answer is not the same

9x > 81
x > 81/9
x > 9
first one no:
when dividing by a negative you need to flip the inequality sign
-5x > 0 = x < 0
x<0 doesn't equal x>0

the second
x> 81/9
x> 9
A 3-mi cab ride costs $3.00. A 6-mi cab ride costs $4.80. Find a linear equation that models cost c as a function of distance d.
you should have posted as a new question
Can you help me on this problem as well? (or anyone.)

Solve each inequality and check your solution.
