The nature of the roots can be determined by the determinant of the equation. The determinant is:
b² - 4ac
If this is positive, there are two roots
If this is 0, there is only one root
If this is negative, there are complex roots
Answer: y-intercept
Explanation: A point is classified as (x, y) and in order for this ordered pair to be a y-intercept, we need to have the x-coordinate be 0.
Since the x-coordinate is 0, this is a y-intercept.
Answer:
They are both negative
Step-by-step explanation:
the given coordinate is in quadrant IV and when reflected over the y axis, quadrant IV becomes quadrant III which is (-,-)
X² - 10x = 46
10/2 = 5; 5²+ 25 add 25 to both sides
x² - 10x + 25 = 46 + 25
so the number you have to add to complete the square is 25.
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
