A discriminant test is one that tells whether a formula has one, two or no solutions.
The equation represents a parabola because the discriminant of a parabola has either x or y squared and not the both.
<h3>What is a discriminant test?</h3>
A discriminant test is a test that tells whether there are one, two or no solutions for a formula.
The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac.
The discriminant of a quadratic equation is given as ax2 + bx + c = 0
A discriminant is said to be a parabola either x or y is squared and not both unlike that of an eclipse and a hyperbola.
With the given equation, x^2 − 4xy + 3x + 25y − 6 = 0, only x is squared and not both x and y.
Thus, the equation represents a parabola because the discriminant of a parabola has either x or y squared and not the both.

Answer:
B) 3.16 pounds
Step-by-step explanation:
Accuracy is how close a measured value is to the actual or true value. The balance is accurate to the nearest 1/100 pound; thus, the highest level of accuracy appropriate to the limitations of the balance.
The answer is as follows...i tried to post this on the other question you asked but it didnt attach so i apologise
