5x+6y=3 2x-3y=12 6y=3-5x 2x=12+3y 3y=2x-12 Therefore, 6y=2(2x-12)=4x-24 4x-24=3-5x 9x=27 x=3

The chain rule is a method that allows you to differentiate a function of a function, which can be of the form y = f[g(x)]. That is, g is a function of x and f is a function of g, which in turn is a funct...

Given 924 x 438 = 404712, we must consider the changes made to THIS question that leads to 9.24 x 43.8 924 => 9.24: we divide 924 by 100 to get 9.24
438 => 43.8: we divide 438 by 10 to get 43....

Find the values of y such that log₂(11y-3)-log₂3-2log₂y = 1

Power law: 2log₂y = log₂y²

Product law: log₂(11y-3) -...

In differentaition, it is all about multiplying and taking away. Look at the first integer and the number that it is in the power off. You have to simply times the integer with the power of number and the...
