They are at: x = -2.5 and x = 4
The x-intercept is 4 and the y-intercept is 5. All you have to do is use the zerofactor and then divide. 20/5 20/4.
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
y = 2x2 - 3x - 20 ∴ y = 2x2 - 8x + 5x - 20 ∴ y = 2x(x - 4) + 5(x - 4) ∴ y = (2x + 5)(x - 4) The x intercepts occur when y = 0, which happens when either of the two factors on the left side of the equation equal zero. This means that they are at the points (-5/2, 0) and (4, 0).
99/9 + 9 = 20
x=20 y=-3
x^2+8x=20 x^2+8x-20=0 (x+10)(x-2)=0 x=-10 and x=2 are the roots (intercepts) (-10,0) and (2,0) are the x-intercepts.

y = 0 gives 0 = - x - 20 so that x = -20 So the intercept is (-20, 0)
They are at: x = -2.5 and x = 4
for the equation:5x + 10y = 20, the two intercepts are:x = 0 , y = 2 or (0,2)y = 0 , x = 4 or (4,0)The graph is a straight line passing through the two intercepts (0,2) and (4,0)
The x-intercept is 4 and the y-intercept is 5. All you have to do is use the zerofactor and then divide. 20/5 20/4.
2x+5y=20 Solve for y -2x -2x 5y=20-2x 5 5 5 y=4-2x 5
If you mean: 4x+5y=-20 then the y intercept is (0, -4) and x intercept is (-5, 0)
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
x-intercept | -10 y-intercept | 4 slope | 2/5 = 0.4
