If: 20x+5y = 15 Then: y = -4x+3
x+20x = 60000 21x = 60000 x = 60000/21 = 2857.'142857' recurring
x2 + 20x +0 =30 [(20/2)2 =100] x2 + 20x + 100 =30 +100 √(x+10)2=√130 x+10=√130 x= −10+√130 √ means square root
If: 20x+80y = 0 Then: 80y = -20x And: y = -0.25x So the slope is -0.25 and it has no y intercept
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
If: 20x = 3.65 Then: x = 0.1825

Standard form is y=ax2+bx+c50x2=20x-250x2-20x+2=02(25x2-10+1)=0Discriminant is b2-4ac(-10)2-4(25)(1) = 0Discriminant is 0 and the function has two real zeros.
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
2x + 20x = 111,45222x = 111,452x = 5,066

Improved Answer:-If: 20x+27 = 143Then: x = 5.8
If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)
10 - 20x = (10) (1 - 2x)
20x=130 x=130/20 x=6.5 or 13/2
