C, because the independent variable would be the variable that is changing -- in this case, the temperature. The dependent variable changes according to the independent variable, and is called so because it depends on the temperature of the pool.
-3x-42>3
-3x>45
x<-15
I chose x<-15 because through the process of elimination, if it was an equality, x=-15. Since it is an inequality, when dividing both sides by a negative, the sign switches.
I believe the answer would be 1086.4
Please give a like if I’m right and tell me in the comments if I’m wrong.
Hope this helped :)
I believe its 44 but im not 100% sure
