-4x-2y=-12<br> 4x+8y=-24
lutik1710 [3]

Answer:

x = 6, y = -6

Step-by-step explanation:

-4x - 2y = -12

4x + 8y = -24   +

-----------------------

6y = -36

y = -36/6

y = -6

4x + 8y = -24

4x + 8*(-6) = -24

4x = -24 + 48

4x = 24

x = 6

PLEASEE Can someone help me with this and show the work
Orlov [11]

Answer:

The vertex form is: y =  3(x-2)^2 + 7 . The vertex is (2, 7)

Step-by-step explanation:

Write the function: y = 3x^2 - 12x + 11 in vertex form

The vertex form of a quadratic equation is:

y = m(x - a)^2 + b where (a,b) is the vertex

For y = 3x^2 - 12x + 11

Solve for m

y = 3(x^2 - 4x) + 11

Complete the Square:

y = 3(x^2 - 4x + 4) + 11 - 4

y = 3(x - 2)^2 + 7

The vertex then is (2, 7)

Sitting on a park bench, you see a swing that is 100 feet away and a slide that is 80 feet away. The angle between them is 30 de
leva [86]

We are given : Distance of the swing = 100 feet.

Distance of slide = 80 feet.

Angle between swing and slide = 30 degrees.

We need to find the distance between the swing and the slide.

Distance of swing, distance of slide and distance between the swing and the slide form a triangle.

We can apply cosine law to find the distance between the swing and the slide.

c^2 = a^2 +b^2  - 2ab cos C

c^2 = 100^2 +80^2 - 2(100)(80) cos 30°

c^2 = 10000 + 6400 -2* 8000 (\frac{\sqrt{3}} 2)}

c^2 = 16400 - 8000\sqrt{3}

c^2 = 16400 - 13856

c^2 = 2544

c =\sqrt{2544}

c= 50.44

c = 50 feet approximately.

<h3>Therefore, the approximate distance between the swing and the slide is 50 feet.</h3>

What is the following quotient? 1 divided by 1+ square root 3
ollegr [7]

Answer:

4th option

Step-by-step explanation:

The given expression is:

\frac{1}{1+\sqrt{3}}

In order to simplify this expression we have to multiply and divide it with the conjugate of the denominator i.e multiply and divide the entire expression with 1-\sqrt{3}, as shown below:

\frac{1}{1+\sqrt{3}}\\=\frac{1}{1+\sqrt{3}} \times \frac{1-\sqrt{3}}{1-\sqrt{3}}\\=\frac{1-\sqrt{3}}{(1)^{2}-(\sqrt{3})^{2}}\\\\ =\frac{1-\sqrt{3}}{1-3}\\\\ =\frac{1-\sqrt{3}}{-2}\\\\ =\frac{-1(1-\sqrt{3})}{2}\\\\ =\frac{-1+\sqrt{3}}{2}

Thus, 4th option gives the correct answer.
