Many statements can be true about those parabolas, so you need to include the list of choices.

This is the list of answer choices that I found for this same question:

<span>A. The second parabola opens downward.
B. The second parabola opens upward.
C. The points of intersection are on the x-axis.
D. The points of intersection are of equal distance from the y-axis.

While A, B or C may be or may not be true, D has to be true.

D. has to be true because the symetry axis of both parabolas is x = 0, so the intersection points will  be necesarily to the same distance of the x-axis and the y-axis.

Answer: </span>
<span>The points of intersection are of equal distance from the y-axis. </span>

What is the value of the discriminant, b2 − 4ac, for the quadratic equation 0 = x2 − 4x + 5, and what does it mean about the num
sleet_krkn [62]

Answer:

The discriminant is −4, so the equation has no real solutions.

Step-by-step explanation:

In the equation 0 = x² - 4x + 5, a is 1, b is -4, and c is 5.

Plug in these values into b² - 4ac, and simplify:

b² - 4ac

(-4)² - 4(1)(5)

16 - 20

= -4

So, the discriminant is -4. This means that the equation has no real solutions, because the discriminant is a negative number.

The correct answer is that The discriminant is −4, so the equation has no real solutions.

kupik [55]

Answer:

6/5m

or

1 1/5m

Step-by-step explanation:

5 - 3 4/5 = x

5/1 - 19/5 = x

5/1(5/5) - 19/5 = x

25/5 - 19/5 = x

25/5 - 19/5 = 6/5

x = 6/5 or 1 1/5
