H:F F:B7:4 8:550 bungalows, so bungalows have been multiplied by 10 to get from 5 to 50. So now we have to do the same process to the flats so we multiply 8 by 10 to get 80 flats. Now we need to get to 80...

y=e^x+2 , we want to make x the subject, x+2=ln(y), x=ln(y)-2, now that x is the subject, the inverse of the function can be found by swapping the x and the y. Therefore the inverse function ...

X=1/2X=3

x²-4x-3 First factorise into squared form and expand.(x-2)²=x²-4x+4Balance the equations.x²-4x+4 needs to be x²-4x-3This leads to(x-2)²-4-...

Y = x + 4y = x² + 4x(as both are equal to y, they can be equated)So: x² + 4x = x + 4(Rearrange to make the equation equal 0 - subtract x and 4)x² + 3x - 4 = 0(factorise)(x...
