\frac{x}{2}≥-4

Pretend the greater than or equal to sign is an equal sign, we will substitute it back in later.

x/2 = -4
Multiply both sides by 2 to get x alone
x = -8
Substitute the greater than or equal to sign back in and voila!
x≥-8

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>

a store sign reads take 75% off the original price when you take an additional 15% off the sale price which is 60% off the regul
Lelu [443]
I you take 75% off the original price, 25% remains.

If you take 60% off the original price, 40% remains. Taking 15% off that means you take off an additional 0.15*40% = 6% of the original price, so end up with
  40% -6% = 34%
of the original price. This is considerably more than 25% of the original price.

The store sign is not accurate, because the "additional 15%" is of the sale price, not the original price.
