1st step: we multiply the equation by (4-y) and we get: x(4-y)=(2y-1) 2nd step: we bring the equation to the form: 4x-xy=2y-1 3rd step: now we isolate all the y terms on the same side: 2y+xy=4x+1 4th step...
S=D/T Max= 455(upper bound)/61.5(lower bound)= 910/123 m/s Min= 445(lower bound)/62.5 (upper bound) = 178/25 m/s Max - Min= 856/3075 m/s
We know x is inversely proportional to P, so immediately we know their relationship is of the form x = k/P , where k is a constant. We are also given some conditions we can use to solve for k: when x = 2,...
The important thing here is to try and find the bottom bracket in the top bracket ie the numerator
Notice that (3x-3) can be divided by 3 and therefore (3x-3) can be written as 3 multiplied by (x-1...
First, we can temporarily make this an equation rather than an inequality to make it easier to solve. We replace the “<” with an equals sign “=”. The inequality now becomes an equality: 2x - 10 = 6 - 2...
