1. (x - 2)/ 4 - (3x + 5)/7 = - 3, x = ?

Reika [66]

Answer:

x = 10
B. 3/7

Step-by-step explanation:

1. (x - 2)/ 4 - (3x + 5)/7 = - 3

7(x -2) -4(3x +5) = -84 . . . . . . . multiply by 28

7x -14 -12x -20 = -84 . . . . . . . . eliminate parentheses

-5x -34 = -84 . . . . . . . . . . . . . . collect terms

-5x = -50 . . . . . . . . add 34

x = 10 . . . . . . . . . . . divide by -5

2. 1/(1 + 1/(1 - 1/x)) = 4

1 = 4(1 +1/(1 -1/x)) . . . . multiply by the denominator

-3 = 4/(1 -1/x) . . . . . . . eliminate outer parentheses, subtract 4

-3(1 -1/x) = 4 . . . . . . . multiply by the denominator

-3 +3/x = 4 . . . . . . . . eliminate parentheses

3/x = 7 . . . . . . . . . . . add 3

x = 3/7 . . . . . . . . . . . multiply by x/7

Find the perimeter of quadrilateral ABCD. Round to the nearest tenth.

Olegator [25]

Answer:

14.6 units

Step-by-step explanation:

AB = $\sqrt{(1-3)^2+(3-5)^2}$

AB = $\sqrt{8}$

BC = $\sqrt{(3-1)^2+(-1-3)^2}=\sqrt{20}$

CD = $\sqrt{(5-3)^2+(3-(-1))} = \sqrt{20}$

DA = $\sqrt{(5-3)^2+(3-5)^2} = \sqrt{8}$

Primeter = $\sqrt{8} + \sqrt{20} + \sqrt{20} +\sqrt{8} = 14.6$

A hyperbola is given by the equation x^2+2xy−y^2+x = 2. Use implicit differentiation

Mekhanik [1.2K]

$\bf x^2+2xy-y^2+x=2\qquad 
\begin{array}{llll}
(1&,&2)\\
x_1&&y_1
\end{array}\\\\
-------------------------------\\\\
2x+2\left( 1\cdot y+x\frac{dy}{dx} \right)-2y\frac{dy}{dx}+1=0
\\\\\\
2x+2y+2x\frac{dy}{dx}-2y\frac{dy}{dx}+1=0
\\\\\\
\cfrac{dy}{dx}(2x-2y)=-1-2x-2y\implies \cfrac{dy}{dx}=\cfrac{-1-2x-2y}{2x-2y}
\\\\\\
\left. \cfrac{dy}{dx}=\cfrac{2x+2y+1}{2y-2x} \right|_{1,2}\implies \cfrac{2+4+1}{4-2}\implies \cfrac{7}{2}\\\\
-------------------------------\\\\
$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-2=\cfrac{7}{2}(x-1)\implies y-2=\cfrac{7}{2}x-\cfrac{7}{2}
\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}
\\\\\\
\boxed{y=\cfrac{7}{2}x-\cfrac{3}{2}}$
