y=x(x−1)y= x^2-xdy/dx= 2x-1
Atoms of the same element with different numbers of neutrons
The movement of molecules against their concentration gradient (low concentration to high concentration), across a membrane using energy.
Example solve the following, equation 1: x2+2y=9 equation 2: y=x+3In this example we have to use substitution, therefore we sub in equation 2 into 1 to get the following x2+2(x+3)=9 ...
2^6 = 64 (2x2x2x2x2x2)6^2= 36 (6x6) 64+36= 100Square root of 100= 10 (10x10=100)
