Find the two given functions by the given relation
3x²-y²=25

Isolate y on the left-hand side, and solve for y. 

I'll do the first one. 

(a) 3x²-y²=25 
-y²=25-3x² 
y²=3x²-25 
y = √(3x²-25)

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
