Answer = 2x^3/3 + 3x^2/2 + 8x + CThis is an example of numerical integration from C1. To begin to answer this question, we can integrate each term at a time. To integrate this function, we raise the power...

7x < -2 + 2x5x < -2x< -2/5

In my opinion the easiest way of approaching simultaneous equations is to first number your equations. 5x+2y=82x+y=7This helps avoid confusion later in the working. Next choose the variable you want to s...

Step 1) Replace f(x) with y: y= 2x - 7
Step 2) Switch around the x and y values: x = 2y - 7
Step 3) Solve to find y by itself: x = 2y - 7 x ...
