Determine the discriminant for the quadratic equation -3 = x^2+4x+1 . Based on the discriminant value, how many real number solu
djverab [1.8K]

Answer:

1 real

Step-by-step explanation:

The discriminant is:

b^2-4ac

which comes from the quadratic formula.

The rules are:

If the discriminant is > 0, there are 2 real solutions

If the discriminant is = 0, there is 1 real solution

If the discriminant is < 0, there are 2 imaginary solutions

(there are 2 other situations involving square roots, but these are the most basic ones in Algebra 2 books when you study quadratics)

First, we have to get that quadratic in standard form, which means getting everything on one side of the equals sign and setting it equal to 0:

x^2+4x+4 = 0

where a = 1, b = 4, c = 4

Filling in the discriminant:

4^2-4(1)(4)

gives us

16 - 16 = 0

Therefore, our quadratic has one real solution.  Factor it and see if you'd like, to prove that it is true.

Study the triangle what can you conclude about the angle measures
lyudmila [28]
If 30 60 90 right triangle then ratio of short leg : long leg : hypotenuse = a : a√3 : 2a

in this case

short leg = 4
long leg = 4√3 (short leg times √3)
and
hypotenuse = 8 (twice of short leg)

so answer is A.
The angle measures are 30, 60 and 90

Does anyone know which one it is ?
hammer [34]

Answer:

The slope of the line is undefined

Step-by-step explanation:

The given line is a vertical line.

The slope of any vertical line is undefined.

Let us see why by using the slope formula:

m =  \frac{y_2-y_1}{x_2-x_1}

We substitute the coordinates of the points to obtain:

m =  \frac{3 -  - 2}{1 - 1}  =  \frac{5}{0}

This is not defined.
