Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes the discriminant and the number of zeros? The equation has one zero because the discriminant is 1. The equation has one zero because the discriminant is a perfect square. The equation has two zeros because the discriminant is greater than 0. The equation has no zeros because the discriminant is not a perfect square.

Answers

Answer 1

Answer: The correct option is: The equation has two zeros because the discriminant is greater than 0.

Explanation:

First, remember the following conditions:
1. If the discriminant is less than zero, there will be no zeros.
2. If the discriminant is equal to zero, there will be one zero.
3. If the discriminant is greater than zero, there will be two zeros.

For the general equation of the form $ax^2 + bx + c = 0$ , the discriminant is $b^2 - 4ac$ .

Let's find the discriminant and then compare it with the conditions mentioned above.

Given Equation:
$3x^2 -7x + 4 =0$

a = 3, b = -7, c = 4

Now find the discriminant:

$b^2 - 4ac$
$(-7)^2 - 4(3)(4)$
Discriminant = 1

As the discriminant is greater than 0 (which in this case is 1), the equation has two zeros (as mentioned in the above conditions).

Answers

If you would like to know how many rows of flags will Noah have in his display, you can calculate this using the following steps:

72 flags / 6 flags = 12 rows

The correct result would be 12 rows.

12

A system of equations is shown below: 6x - 5y = 5, 3x + 5y = 4. The x-coordinate of the solution to this system of equation is what?Thank you to however can help me with this. I've been having a lot of trouble with this math concept. :)

Answers

6x - 5y = 5
3x + 5y = 4

If the left sides are equal to the right sides then if we add left side of first equation to left side of the second one and right side of the first euation to right side of the second one they still would be equal

   6x - 5y = 5
   3x + 5y = 4
   9x +0y = 9
   9x = 9
   x = 1
