24x2 - 47x + 20 has roots of 4/3 and 5/8 IE factorises as (3x - 4)(8x - 5)
Check: 24 x 16/9 - 47 x 4/3 = 42 and 2/3 - 62 and 2/3 = -20
and 24 x 25/64 - 47 x 5/8 = 9.375 - 29.375 = -20

What is the factored form of 15x plus 32x -28?
15x + 32x - 28 = 47x - 28 = (√47x)2 - (√28)2 = (√47x)2 - (2√7)2 = (√47x - 2√7)(√47x + 2√7)

How do you solve this by using the quadratic formula 28x2-47x equals 15?
28x^2 - 47x = 15 28x^2 - 47x - 15 = 0 ax^2 + bx +c = 0, so: a = 28 b = -47 c = -15 quadratic formula: [-b^2 + sqrt(4*a*c)] / 2*a AND [-b^2 - sqrt(4*a*c)] / 2*a [47^2 + sqrt(4*28*-15)] / 2*28 AND [47^2 - sqrt(4*28*-15)] / 2*28 then just do the math

Straight line mx equals 5y plus 4 has same gradient as line 7x plus 6y plus 5 Find value of m?
mx = 5y + 47x + 6y + 5 = 0If they have the same slope, then we know that Δy/Δx in the first line is equal to Δy/Δx in the second one. Let's solve the second equation for y then:y = (5 + 7x) / -6∴y = (-7/6)x - 5/6So we know it's slope is -7/6. Now let's rearrange our other line appropriately:y = (m/5)x - 4/5So the slope of our second line is m/5, which we know is the same as the slope of our other line, -7/6. We can say then that:m/5 = -7/6∴m = -35/6 = -55/6 ≈ -5.8333...
