Since h(x) =18 all you have to do is plug in 18 into the x, and then in would be h(18) = 2(18) + 4. If you multiply first it would be h(18) = 36 + 4. All you have to do is add 4 to 36, which would equal h(18) = 40

Answer:
-1,9
Step-by-step explanation:
You use the equal values method to combine the two equations
-3x+6=9
then subtract 6 on both sides of the equal sign
nine minus six is 3
-3x=3
divide negative three on both sides to isolate the x value
to get....
x=-1
then plug the x value back in to find the y value
(you can plug in to one of them but I would plug into both of them just for double checking) ALWAYS CHECK YOUR WORK
3+6 is 9
9=9 check!
Answer:
Work Shown:
Therefore -7 goes in the first box, and goes in the second box.
24 - x = -12 so what do is just add the two together so 24 + 12 = 36 and since it ended on a negative number, the temperature change is -36!!
