Find the slope of the equation y=5x^2-3x+7
0.5x=12-y y=10 solve for x
If I make $5 profit for every baseball I sell, and $7 profit for every basketball I sell, and I sold 45 total balls for a profit of $275 last week, how many baseballs and how many basketballs did I sell?
5x+7y=275 x+y=45 X = 20 baseballs Y = 25 basketballs
needs and Colin will reply soon.
