If: 20x = 3.65 Then: x = 0.1825
20x=130 x=130/20 x=6.5 or 13/2
5x2 + 20x = 5x (x + 4)
It is a parabola, which passes through the origin and is symmetric about the y axis.

Combine all lie term: x + x - 22x = -20x 2 + 1 = 3 So the answer is -20x +3 or 3 - 20x
If: 20x = 3.65 Then: x = 0.1825
symmetric about the y-axis symmetric about the x-axis symmetric about the line y=x symmetric about the line y+x=0
x2-20x+100 = (x-10)(x-10) when factored
20x=130 x=130/20 x=6.5 or 13/2
The graphs of the two equations will intersect when x² + 20x + 100 = y = x² - 20x + 100 Subtracting x² +100 from both sides you get 20x = -20x that will only be true when x = 0. At x = 0, y = 100 for both equations - so the point of contact would be (0,100)
5x2 + 20x = 5x (x + 4)
It is a parabola, which passes through the origin and is symmetric about the y axis.
x+20x = 60000 21x = 60000 x = 60000/21 = 2857.'142857' recurring
5x2 + 20x = 0 5x(x + 4) = 0 x = 0 and -4

50x squared equals 20x-2 equals zero is not possible, for 20x-2 = 0 --> x = 1/10 While 50x2 = 0 means that x should be zero. So either 50x2 =/ 20x-2 or 20x-2 =/ 0
