It's a two part question. First Part Expand the equation the left hand side to get a^(2)*x-b^(2)*x^3 thus comparing co-efficients a^2=25 and b^2=4 thus a= 5 b=2 Second Part Therefore b^(-a) ...
7x+3y-4 > 5y-19x
Adding 19x to both sides:
26x+3y-4 > 5y
Subtracting 3y from both sides:
26x-4 > 2y
Divide both sides by 2 to put the expression in its simplest...
The best way to remember derivatives is to use algebra, and the general function is y = axn -> dy/dx = anxn-1
So for this equation dy/dx = (3x3)x3-1 + (2x1)xGAAnswered by George A. • Maths tutor2820 Views
