For all values of x,<br> x² + 6x - 2 = (x+p)² + q<br> Find the value of p and the value of q.
Vlad [161]

Step-by-step explanation:

{x}^{2}  + 6x - 2 =  {x}^{2}  + 2px +  {p}^{2}  + q

2p = 6

{p}^{2}  + q =   - 2

p = 3

{3}^{2}  + q =  - 2

q =  - 11

p=3, q=-11

Show that x + y : x - y= 3 : 2
insens350 [35]

Answer:

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore,  x + y : x - y= 3 : 2 is proved.

Step-by-step explanation:

Given

x + y : x - y = 3 : 2

As

x + y = 3

x - y = 2

Solving to find x and y

\begin{bmatrix}x+y=3\\ x-y=2\end{bmatrix}

x-y=2

-

\underline{x+y=3}

-2y=-1

\begin{bmatrix}x+y=3\\ -2y=-1\end{bmatrix}

solve for y

-2y=-1

Divide both sides by 2

\frac{-2y}{-2}=\frac{-1}{-2}

y=\frac{1}{2}

\mathrm{For\:}x+y=3\mathrm{\:plug\:in\:}y=\frac{1}{2}

x+\frac{1}{2}=3

x+\frac{1}{2}-\frac{1}{2}=3-\frac{1}{2}

x=\frac{5}{2}

so

x=\frac{5}{2},\:y=\frac{1}{2}

Thus,

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore,  x + y : x - y= 3 : 2 is proved.

What is the length of side BC? Round your answer to the nearest tenth.
Inessa [10]

Answer:

D = 2.0 units

Step-by-step explanation:

<u><em>We'll find the length using Distance Formula:</em></u>

Distance Formula = \sqrt{(x2-x1)^2+(y2-y1)^2}

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

D = \sqrt{(-2)^2+(0)^2}

D = \sqrt{4}

D = 2.0 units <em><u>(to nearest tenth)</u></em>
