When solved for x, what is the sum when the roots of the quadratic equation are added?

Anna35 [415]

Answer:

Step-by-step explanation:

x² + 10x + 24 = 0

Here, a = 1, b = 10, c = 24. Factoring using the AC method:

ac = 1×24 = 24

Factors of 24 that add up to 10 are +4 and +6.

Therefore:

(x + 4) (x + 6) = 0

x + 4 = 0, x + 6 = 0

x = -4, x = -6

The roots are -4 and -6. Added together:

-4 + -6 = -10

Answer A.

What is the Inequality for this graph?

mote1985 [20]

Given:

The graph of an inequality.

To find:

The inequality for the given graph.

Solution:

From the given graph it is clear that the boundary line passes through the points (6,0) and (0,-4). So, the equation of the line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-0=\dfrac{-4-0}{0-6}(x-6)$

$y=\dfrac{-4}{-6}(x-6)$

$y=\dfrac{2}{3}(x-6)$

$y=\dfrac{2}{3}x-4$

The area under the boundary line is shaded and boundary line is a dotted line it means the points on the line are not included in the solution set. So, the inequality sing must be <.

$y$

Therefore, the required inequality for the given graph is $y$ .

Answer:

1) Variables = 11a , 4a

Constants = 0

Coefficients = 11 , 4

2) Variables = 3x , 7x

Constants = 6 , -4

Coefficients = 3 , 7 , 6 , -4

3) Variables = -12m , +4m

Constants = -3 , 16

Coefficients = -12 , 4 , -3 , 16

4) Variables = 6k , k

Constants = -4 , -2

Coefficients = 6 , 1 , -4 , -2

5) Variables = -5p , -2p

Constants = 3 , 13

Coefficients = -5 , -2 , 3 , 13

6) Variables = -10r , -r , -6r

Constants = 11

Coefficients = -10 , -1 , -6 , 11

7) Variables = -5n

Constants = 19 , -8 , 14

Coefficients = -5 , 19 , -8 , 14

8) Variables = 13y , -2y

Constants = 18 , -5

Coefficients = 13 , -2 , 18 , -5

9) Variables = 8a , 3a , -7b , -2b

Constants = 1

Coefficients = 8 , 3 , -7 , -2 , 1

10) Variables = 11x , 2x , -4y

Constants = 8

Coefficients = 11 , 2 , -4 , 8
