What is a multi-step equation that equals 31?
2n+4=66
What is the solution for the equation -x plus y equals 4 and the equation 2x plus y equals 4?
x = 0 and y = 4
What are the zeros of 0 equals 9x to the second power - 12x plus 4?
Presumably this is a quadratic equation question in the form of: 9x2-12x+4 = 0 When factored: (3x-2)(3x-2) = 0 Solution: x = 2/3 and also x = 2/3 (they both have equal roots)
What is a 4 step equation that equals 8?
Full
Is 8t plus 4 equals 76 an equation?
Yes, a linear equation in t.
Solve the quadratic equation using factoring 9x2 - 16 equals 0?
(3x+4)(3x-4)=0 x=±4/3
What is the solution set for 9x2 equals 36x?

What is the range of the linear equation if y equals 3x-5 and the Domain equals 0 1 2 or 3?
The range is {-5, -2, 1, 4}
What is the discriminent of 9x2 plus 12x equals 2?
It is: 122-4*(9*-2) = 216
What is the range of y equals -4x?
This is the equation of a line with slope -4 and y intercept at 0. The domain is all real numbers as is the range.
What are the intercepts of 9x2 plus 4y equals 36?
9x2 + 4y = 36∴ 4y = 36 - 9x2∴ y = 9 - 9x2/4also:∴ 9x2 = 36 - 4y∴ x2 = 4 - 4y/9∴ x = (4 - 4y/9)1/2This equation represents a parabolic curve, so we know it will intercept the y-axis at one point, and the x-axis at either zero or two points. Let's start with the x-axis:y = 9 - 9x2/4Let y = 0:∴ 0 = 9 - 9x2/4∴ 0 = 36 - 9x2∴ 9x2 = 36∴ x2 = 4∴ x = +/- 2So the curve intercepts the x axis at the points -2, 0 and 2, 0As for the y axis:x = (4 - 4y/9)1/2Let x = 0:∴ 0 = (4 - 4y/9)1/2∴ 0 = 4 - 4y/9∴ 0 = 45 - 4y∴ 4y = 45∴ y = 45/4 = 11 1/4So the curve intercepts the y axis at the point 0, 11.25
What is the discriminant of the equation 9x2-12x plus 4 equals 0?
9x2 - 12x + 4 = 0 is of the form ax2 + bx + c = 0 where the discriminant, D, can be found by D = b2 - 4ac First, you find the values of a, b and c: a = 9 b = -12 c = 4 Now you can find D: D = (-12)2 - (4)(9) = 144 - 36 = 108 D = 108
