Answer:

No solution

Step-by-step explanation:

12q + 40 = 12q - 54

There is no solution because the two equations aren't equal and each equation has the same slope bu didn't y intercept values. Therefore having no solution.

Answer:

Step-by-step explanation:

To solve 4(3q+10)=6(2q-9)

Open the brackets

12q+40=12q-54

Collect like terms

12q-12q=-54-40

0=-94

Express the moment of the couple acting on the rod in cartesian vector form. What is the magnitude of the couple moment?
mash [69]
We are given with the vectors
-F = 4i - 3j + 4k
and
F = -4i + 3j - 4k
To get the moment, we determine the cross product between the two vectors
-F x F = 0i + 0j + 0k
The magnitude is 0 but this is if the pivot is the origin. In the couple, the magnitude is 4.

Identify the conic section represented by the equation:<br> x2 + 2x + 2y2 – 12y + 11 = 0<br> 2
wlad13 [49]

Answer:

Equation of the Ellipse

 \frac{(x+1)^{2} }{8} + \frac{(y-3)^{2} }{4} = 1

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the equation

                 x² + 2 x + 2y² - 12 y +11 = 0

      ⇒       x² + 2 x + 1 - 1 + 2(y² - 6 y )+ 11 = 0

                 x² + 2 x + 1 - 1 + 2(y² - 2(3) y+9-9 )+ 11 = 0

     ⇒        x² + 2 x + 1 - 1 + 2(y² - 2(3 y ) +  3²- 3² ) + 11 = 0

By using (a +b)² = a² + 2 a b + b²

               (a -b)² = a² - 2 a b + b²

<u><em>Step(ii):-</em></u>

          x² + 2 x + 1 - 1 + 2(y² - 2(3 y ) +  3²- 3² ) + 11 = 0

    ⇒  ( x+1)² +2( y-3 )² - 1 - 2(9) +11 =0

   ⇒   ( x+1)² +2( y-3 )² - 8 =0

           ( x+1)² +2( y-3 )² = 8

Dividing '8' on both sides , we get

         \frac{(x+1)^{2} }{8} + \frac{2(y-3)^{2} }{8} = 1

      \frac{(x+1)^{2} }{8} + \frac{(y-3)^{2} }{4} = 1

This equation represents the Ellipse
