If the discriminant if a qudratic equation is 4, which statement describes the roots?
pochemuha

Answer:

see explanation

Step-by-step explanation:

The value of the discriminant determines the nature of the roots

• If b² - 4ac > 0 then roots are real and distinct

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 then roots are not real

Here b² - 4ac = 4 > 0

Hence roots are real and distinct

grandymaker [24]

Answer:

1. 11.2

2. -1.4

3. 12

Step-by-step explanation:

The equation of the line that passes through the points A(8,0) and B(3,7) is

\dfrac{x-8}{3-8}=\dfrac{y-0}{7-0},\\ \\y=-\dfrac{7}{5}(x-8).

To find the y-intercept, plug into this equation x=0:

y=-\dfrac{7}{5}(0-8)=\dfrac{56}{5}=11.2.

Two parallel lines have the same slope, so the equation of the line CD is

y=-\dfrac{7}{5}x+b.

This line passes through the point D(5,5), thus

5=-\dfrac{7}{5}\cdot 5+b\Rightarrow b=5+7=12.

Hence, the equation of CD is

y=-\dfrac{7}{5}x+12.

What are the solutions of the quadratic equation below?
Ksenya-84 [330]

Use the quadratic formula -b +/-√(b^2-4(ac)) / 2a

In the given formula a = 7, b = 23 and c = -10

Replace the letters with their values:

-23 +/-√(23^2 -4*(7*-10)) / 2*7

Simplify to get:

x = -23 + √809 / 14 or x = -23 - √809 / 14

Kazeer [188]

Answer:

3 {x}^{2}  + 12x + 5

Step-by-step explanation:

(x^2 + 3x)  +  (2x^2 + 9x + 5) \\  \\  = x^2 + 3x  +  2x^2 + 9x + 5 \\  \\  =  {x}^{2}  + 2 {x}^{2}  + 3x + 9x + 5 \\  \\  = 3 {x}^{2}  + 12x + 5
