2x^2 + 9x + 4 = 0

x^2 + 9/2*x + 2 = 0

x = - 9/4 +- √(81/16 - 32/16) = - 9/4 +- 7/4

x1 = - 1/2

x2 = - 4

Help me someone:((!!!!!
LiRa [457]

Answer:

Hope this helps!

Step-by-step explanation:

2L + 3S = 83

 

4L + 8S = 197

 

Multiplies the top equation by -2.

-4L + -6S = -166

 

4l  + 8S = 197

 

 

Adding them together...

 

2S = 31

 

S = 31/2 = 15.5

 

Plugging into the first equation:

 

 2L + 3S = 83

 

 2L + 3(15.5) = 83

 

2L + 46.5 = 83

 

2L = 83 - 46.5

 

2L = 36.5

 

L = 36.5/2 = 18.25

 

check:

 

2L + 3S = 2(18.25) + 3(15.5) = 36.5 + 46.5 = 83

 

4L + 8S = 4(18.25) + 8(15.5) = 73 + 124 = 197

 

The Large box weighs 18.25

The small box weighs 15.5

The line segment formed by joining points A (-1,y) B (0,0), and the line segment joined by forming points C (6,3) D (8,9) share
Airida [17]

Answer:

<h3>-3</h3>

Step-by-step explanation:

For two parallel lines. their slope are equal

Find the slope of each of the lines

For line A;

m = 0 -y/0+1

mA = -y/1

For line B;

mB = 9 - 3/8 - 6

mB = 6/2

mB = 3

since their slope are equal hence mA = mB

-y/1 = 3

-y = 3

y = -3

Hence the value of y is -3

Given the graph of y=f(x), shown as a red dashed curve, drag the movable blue point to obtain the graph of y=f(x−4)+3.
Sergeeva-Olga [200]

Answer:

See graph in attachment.

Step-by-step explanation:

The graph of y=f(x) is a parabola that has its vertex at the origin.

The equation of the transformed graph is

y=f(x-4)+3

The vertex of this transformed function is

(4,3)

Drag the blue graph up so that the vertex will now be at (4,3).

See graph in attachment.

Find the value of x. x, 50, and 70
Rama09 [41]
X = 60°

To work this out, you would do 50°+70° to get 120°. You would then subtract this from 180° (the total for any triangle) to get the final answer of 60°.
