The first step is to find the y coordinate at the point on the curve where x = e. To do this we subsitute x = e into the equation of the curve, so y = 2ln(2e - x) becomes y = 2ln(2e - e). Simplifying t...
SInce the question requires simplified surd form, it makes sense to use the quadratic formula immediately for this question.
This would give us
x = 6 [+-] squareroot(36-(4x1...
According to the rules of logarithms, when you take a log of something to the power of something, you multiply the log of the base by the power, so in this case, taking logs of both sides would give us...
First we need to multiply out the bracket
7k-21=3k-5
Then we must make sure our variable is only on one side so we need to deduct 3k from both sides
4k-21=-5
First think how you would solve this if it was simply an '=' sign instead of a >
Deduct 5 from both sides
This would give us 6y>3
