Answer:
There is no solution to that equation.
Step-by-step explanation:
First thing to do is to put the second equation in terms of y. To do so the equation becomes y= 2/3x+5. Comparing those two equation you can see that the slopes are the same and thus means that the system has no solution.
Another way to see this is by graphing both of thee equations is a calculator and seeing there are no points of intersection.
You can group first two conjunctions and second two:
.
In first brackets you have common
and in second brackets common is 5:
.
Answer:
The answer is 33.2*F (72.3*F - 39.1*F because the temp. is *dropping* 39.1*F)
Step-by-step explanation:
If there is a negative change in temp. then that is just like subtracting the change from the base degree (F)
