How do I solve this? -------------- I found it, it's on the left side next to the 6. ========= Ok, let's get serious. You can solve for x in terms of y. get the x on one side of the = by itself. ---- 6x+2 = 3y + 4 Subtract 2 6x = 3y + 2 Divide by 6 x = (3y/6) + (2/6) or, x = (3y+2)/6 x = y/2 + 1/3 Either is acceptable

The volume rate of flow R of blood through an artery varies directly as the fourth power of the radius r of the artery and inversly as the distance d along the artery. If an operation is successful in effectively increasing the radius of an artery by 25% and decreasing its length by 2%, by how much is the volume rate of flow increased? 1 solutions Answer 391948 by Alan3354(31509)   on 2012-06-23 11:20:08 (Show Source): You can put this solution on YOUR website! The volume rate of flow R of blood through an artery varies directly as the fourth power of the radius r of the artery and inversly as the distance d along the artery. If an operation is successful in effectively increasing the radius of an artery by 25% and decreasing its length by 2%, by how much is the volume rate of flow increased? -------------- Use F1 for flow, F2 for flow after surgery, r for radius & L for length F1 = k*r^4*L --> F2 = k*(1.25r)^4/(0.98L) F2 =~ k*2.4414/0.98r^4*L F2/F1 =~ 2.4912 Increase = F2/F - 1 = 1.4912 ---------------- It's 2.49 times the original Increased 1.49 times the original, a 149% increase.
