It is 2x2 - 7x + 9
x = -4/3
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
The discriminant is 0.
18x-3 18x-3
It is 2x2 - 7x + 9
-x=-2
x = 1/3
x = -4/3
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
For this, you need the Pythagorean theorem. Let A equal x + 9 Let C equal 26 A^2 + B^2 = C^2 (x + 9)^2 + B^2 = 26^2 x^2 + 18x + 81 + B^2 = 676 x^2 + 18x + B^2 = 595 This doesn't help you find x, but I hope this did something!
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
The discriminant is 0.
18x + 12y = 72 to get x-int. put y=0 18x + (12)(0) = 72 18x = 72 x = 4 your x-intercept is 4. this is the place where the line goes through the x-axis.
x2=18x-80 (im guessing you are trying to find x) x2-18x+80=0 (x-10)(x-8)=0 Therefore: x = 10, 8
y=-18x+17. Since this is already in Slope-Intercept form, we can determine that the slope is negative 18.
