The general equation for a circle is as follows:(x-a)^2+(y-b)^2=r^2where (a,b) are the coordinates of the centre of the circle and r is the radius of the circle.x^2+y^2-4x-8y+11=0In this case, group all x...

To differentiate an equation, the first step is multiplying the coefficients of the variables (the coefficient is the number a variable is already being multiplied by, for example in 6x the coefficient of...

First of all I would find 1% by dividing 1546 by 100:1546/100 = 15.46Then I would multiply this by 24 to find 24%:15.46x24 = 371.04 So 24% of 1546 is 371.04

X 2.87 or -0.87y-0.87 or 2.87

Begin by expanding brackets using FOIL (first, outer, inner, last) method (demonstrated on whiteboard to make clear). Multiplying the first term of each bracket gives 3x², multiplying outer ter...
