**Fluid Imbalances**

The only thing I could really conclude was that perhaps if there is an increase in H+ in the blood then then in order to compensate, K+ might move out of the cells and into the plasma in order to compensate and the H+ would move into the cells? Also acidosis may result in ...

So the area of a triangle is the following: A =( B x H) / 2 Let's plug in what we've been told in the question 24 = (3B x B) / 2 48 = 3B x B 48 = 3B^2 16 = B^2 + or - 4 = B I would go with option C because if you plug in 4 in or -4 for B into the area of a triangle ...

I'm assuming by function form you mean the form of y=mx + b. 2y + 5x = 12 So if we want to put this into function form, we want to isolate y. 2y + 5x = 12 2y + 5x - 5x = 12 2y = 12 - 5x y = -5/2x + 6
