Anderson could provide 0.5x2 + 4x + 8 = 0 has exactly one real root if the discriminant is 0,
<h3>What is quadratic equation?</h3>
Any equation that can be rewritten in standard form as where x represents an unknown, a, b, and c represent known numbers, and where a 0 is true is a quadratic equation. As there is no ax2 term when a = 0, the equation is linear rather than quadratic.
<h3>What is discriminant?</h3>
A polynomial's discriminant is a quantity that depends on the coefficients and enables for some root attributes to be inferred without actually computing them. It is actually a polynomial function of the original polynomial's coefficients.
<h3>According to the given information:</h3>
0.5x^2 + 4x + 8 = 0
The discriminant is computed utilizing:
d = b^2 - 4ac
Thus, we have:
d = 4^2 - 4 * 0.5 * 8
Evaluate
d = 0
The equation has only one real root since the discriminant is 0,

Answer:
the answer is B i think
Step-by-step explanation:
Answer: The answer is (B) They show direct variation because y=x+2 and 10-5=12-7.
Step-by-step explanation: We are given two points (5 7) and (10, 12) and we are to select the correct statement about the two given points.
Since we have
7 = 5 + 2 and 12 = 10 + 2, so we can directly say that the equation of the line passing through the two points will be
y = x + 2.
Since we can directly find the relation between x and y, so we can say that they show direct variation because y=x+2 and 10-5=12-7.
Thus, the correct option is (B).
