As we have two equations of x for y we can make these equal to each other. This gives the following:2x2 - 7x + 4 = 4x - 1As with any quadratic we want to make it equal to 0. This gives the foll...
X can be found by using the quadratic equation. x = -b plus or minus (b2-4ac)1/2/2a. We find that x=-5/2 plus or minus (53)1/2/2.
We are given the second term both as a number and an equation, so we can saya + 6b = 8We can then estimate the fifth term by continuing the pattern of adding 4b to each term in the sequence, which gives:T...
Let:x = number of boysy = number of girlstherefore 2(x+5) = (y+8)2x + 10 = y - 8y = 2x + 2
When using Pythagoras' theorem, the hypotenuse squared should equal the square of the other two sides added together, so (a2=b2+c2). We also know that for Pythagoras' theo...
