Graph C is the correct graph for that gunction
The total number of both men and women surveyed was 305+279+152+459= 1195. Of this total, 279 women cooked dinner so 279/1195=0.23. This would compare with men which would be 305/1195=0.26 or slightly higher probability.
You're looking for an inequality of the form , or , or .
Start with
Notice that 375º is the midpoint of this interval of temperatures. If we subtract all sides by 375º, then we get
so we can set and , and we can rewrite this inequality in terms of absolute values as
Answer:

So, the equivalent expression is
{18x}^{2} + 30xy - 24x
