First differentiate the function with respect to x, dy/dx=6x+5 this finds the gradient function now calculate the gradient at point A by inputing x=2 into the gradient function 6(2)+5=17. Now using y=mx+c...

A monopoly is a type of market structure where by the market is dominated by one company. Due to the lack of participants in the market, the monopoly has the ability of charging high prices with low quant...

2x² + 6x + 62(x² + 3x + 3) => Factor out 4 from each term so the x² term of the quadratic has 1 for a coefficient.2[(x + 3/2)² - d + 3] => Here, we've div...

Firstly group the like terms to make the expression (5a+4a^2) and then factor out 'a' as it is a common term.This makes the expression ( a(5+4a))

y - 2x = 3 x² + y² = 18Step 1- re-arrange the first formula to find y: y = 3 + 2x Step 2- Substitution: x² + ( 3 + 2x )² = 18 Step 3- Expand the brackets: ( 3 +...
