Need help factoring ..need positive exponents
2x(6x-1)^1/2 + 3^2(6x-1)^-1/2
This is what I have
(6x-1)^-1/2x[2(6x-1)+3x]
(6x-1)^-1/2x[12x-2+3x]
(6x-1)^-1/2x(15x-2)
My question says use the slope formula to calculate the slope of the line that passes through the points (4,7) and (6,2). How do you do that?
