What us the value of the discriminant of the quadratic equation -2^2=-8x+8 and what does its value mean about the number of a re
svlad2 [7]

ANSWER

The discriminant is zero.

The given equation has one real root.

EXPLANATION

The given quadratic equation is:

- 2 {x}^{2}  =  - 8x + 8

We rewrite this in the form;

a {x}^{2}  + bx + c = 0

- 2 {x}^{2}  + 8x  - 8 = 0

This means that,

a=-2, b= 8, c=-8

The discriminant is given by;

D=b² - 4ac

That is:

D =  {8}^{2}  - 4( - 2)( - 8)

D =  64  - 64 = 0

Therefore the discriminant is zero.

This tells us that the quadratic equation has one real root.

In order words, the given quadratic equation has a repeated real root.

Is (1,2) the point of intersection of y=3x-1 and y=-x+3?​
Luden [163]

Answer:

yes

Step-by-step explanation:

Solving the 2 equations to find the point of intersection

y = 3x - 1 → (1)

y = - x + 3 → (2)

Since both equations express y in terms of x, equate the right sides

3x - 1 = - x + 3 ( add x to both sides )

4x - 1 = 3 ( add 1 to both sides )

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting x = 1 in (2)

y = - 1 + 3 = 2

Thus (1, 2) is the point of intersection
