7xy+3y2=10x 3y2=10-7xy 3y2=x(10-7y) 3y2/10-7y=x
solve 642/3 ... note X2/3 = X2 x 1/3 therefore 642/3= (642)1/3= (4096) 1/3= 16
Using quotient rule, let u = 2x+12 and v = 1-x. Then we differentiate u and v separately, so u' = 2 and v' = -1. The formula for the quotient rule is: (vu' - uv')/v^2. Plugging in our values into this equ...
Find the value of 9-1/2. For this question we need to know indices rules. We apply two rules here as the power is negative and because it's a fraction. First, let's tackle the negative power ru...
We know the presence of the quadratic means there must be two solutions for x. We can solve this problem by treating the formulas for the graphs as simultaneous equations. We can substitute in the formula...
