The temperature at a ski resort was 12°F at 5:00 A. M. If the temperature increased by 1.5°F each hour, what would be the temperature at 12 noon?

22.5° F at 12 noon

Step-by-step explanation:

If it is already 12° F. at 5:00 am then there is only 7 hours to go till 12 noon. So if there is only 7 hours to go and it rises 1.5° F per hour, you would take 1.5 times 7 hours left and get that it will rise 10.5° F in that 7 hours and it is already 12° F so they will combine to make it 22.5° F at 12 noon.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
