Rearrange equation into the form: y = mx + c
m = gradient
3x + 5y = 7
5y = -3x + 7
y = (-3/5)x + (7/5)
gradient = (-3/5)
1) 2x + 3y = 6
2) 3x + 2y = 5
We can either use substitution or elimination.
Using elimination:
Multiply equation 1) by 3 and multiply equation 2...
6x+4y=16, 6x+15y=-6
11y=-22
y=-2
3x=8+4=12 x=4
x=4, y=-2
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...
