it must always have one of the sign
-9x+5<17 answer x >-4/3 how I do to it
subtract -5 from both side and you get 12. so it be -9x<12
than you divide -9 from both side because you want x by it self you get -4/3 but you have to flip the sign since is negavite and you will be left over with ×>-4/3
6.38 x 3 = $19.14 for 3 pairs of earrings
19.14 + 2.50 = $21.64 total
The slope of the function is most positive either side of x=0 and x=2π.
On the interval [0, π/4], the average slope is

On the interval [7π/4, 9π/4], the average slope is

The average rate of change is highest on the intervals [0, π/4] and [7π/4, 9π/4].
