The point A = (x', y') lies on the line y = 2x² - 8x +2. And we are given that y' = -4.Therefore we have tha...

First, calculate the gradient of the line (m) using the equation using dy / dx.m = dy / dx = (y_2 - y_1) / (x_2 - x_1) = (12 - 4) / (8 - 4) = 8 / 4 = 2.As you now know the gradient of the line and points ...

If you having trouble visualising it, try drawing a diagram. Start with SohCahToa. As A is opposite side BC=9, Opposite =9 As AB=12 is adjacent to A, Adjacent=12 Both opp...

To find the midpoint we add both x coordinates together and divide by 2. 2+8= 10, 10÷2 = 5 We then add both of the y coordinates together and divide by 2. 12+2 = 14, 14÷2 = 7Then we are given the coord...

To solve a simulatious equation, you should place the contents of each bracket equal to 0.
so (2x+3)=0 and (4x-2)=0
Lets start with the equation on the left.
2x+3=0
Minus...
