Find the y-intercepts of 16y squared equals 120x-225?
We are told: 16y2 = 120x - 225 The y-intercepts will happen where x equals zero, so we can say: 16y2 = 120(0) - 225 16y2 = -225 y2 = -225 / 16 y = √(-225 / 16) y = ±15i/4
How do you find how many x intercepts the parabola has using the discriminant?
If the discriminant is negative, there are 0 interceptsIf the discriminant is zero, there is 1 interceptIf the discriminant is positive, there are 2 intercepts
What is the least number of intercepts for a line?
Zero
How do you find the x and y intercepts of an equation?
Oh, finding the x and y intercepts is like finding little treasures in your painting. To find the x-intercept, you set y to zero and solve for x. To find the y-intercept, you set x to zero and solve for y. Remember, there are no mistakes in mathematics, just happy little accidents.
Why do you equate the equation to zero?
Not all equations are equated to zero, but usually we set a function equal to zero if we want to find its x intercepts, or where the graph of the function crosses the x axis.
How many x intercepts are in y equals 2x2 plus 4x plus 3?
None because the discriminant of this quadratic equation is less than zero.
Find the x-intercepts for the parabola defined as y equals -9 x to the second power-6x plus 9 answer as two ordered pairs?
The x intercepts are when y=0. Substitute the zero in for all y and then solve. Use quadratic formula and reduce. I got (-1+/- sqrt 10)3 about .72075922 and -1.387425887
What s the x and y intercepts for 9x-2y equals 27?
An easy way to find the intercepts is to substitue zero into the other variable. y-intercept is when x=0 -2y=27 y=-27/2 y=-13 1/2 is the y-intercept. 9x=27 x=3 is the x-intercept.
What is the least number of intercepts for a circle?
Zero
Why is the least number of intercepts for a circle zero?
4
What is the x-intercepts of f of x equals x plus four divided by x?
Find the x-intercepts of f(x)=(x+4)/x The instructions simply mean that you should set f(x) equal to 0. To get the answer, you must set the numerator equal to zero, so x+4=0. Then x=-4 is the answer.
How do you find the y intercept for x equals 2y2 plus 3y plus 1?
The y-intercept is the place (or places) where x=0 . So if 'x' is 2y2+3y+1 , then all you have to do is find places where 2y2+3y+1 is zero, and those are your y-intercepts.
