How many points of intersection are there between the graphs of the hyperbola and ellipse?
N76 [4]

The point of intersection is the point where two or more functions meet.

The graphs of the hyperbola and ellipse have 0 point of intersection

The given parameters are:

\mathbf{3x^2 - 4y^2 + 4x - 8y + 4 = 0}

\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 0}

To determine the points of intersection, we simply equate both equations.

So, we have:

\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 3x^2 - 4y^2 + 4x - 8y + 4 }

Cancel out the common terms

\mathbf{y^2 - 3y = - 4y^2 - 8y  }

Collect like terms

\mathbf{y^2 +4y^2= 3y   - 8y  }

\mathbf{5y^2= - 5y  }

Divide through by 5

\mathbf{y^2= - y}

Divide through by y

\mathbf{y= -1}

<em>The system of equation does not give room to calculate the x-coordinate at the x-axis.</em>

<em />

Hence, the graphs of the hyperbola and ellipse have <em>0 point of intersection</em>

2(x+3)=x-4<br> please help me &lt;3
vovikov84 [41]
2(x + 3) = x - 4

distribute

2x + 6 = x - 4

either subtract 6 from both sides or add 4. i will be subtracting 6.

2x = x - 10

subtract x from both sides

x = -10
