GREYUIT [131]3 years ago
5 0

Answer:

I believe the answer would be 4.2

Step-by-step explanation:

Reason for this is because I divided 12.6 by 3 and got 4.2, then I added 4.2 + 4.2 and got 8.4, so then I added 4.2 to 8.4 and got 12.6. Hope this helps :)

Find the equation of a line passing through the point (6,−5) and parallel to the line y = 7x + 1. answers : y = 7x − 47 y = −17x
Elan Coil [88]

Answer:

<h2>y = 7x-47</h2>

Step-by-step explanation:

y = 7x + 1.\\(6,-5)\\m= 7\\x1= 6\\y1 = -5\\y-y1=m(x-x1)\\y-(-5) = 7(x-6)\\y+5=7x-42\\y=7x-42-5\\y = 7x-47

Graph the following inequality and then select the correct graph below x + 2 &gt; 1
posledela

Answer:

The graph is attached below.

Step-by-step explanation:

First, we want to isolate the "x" term from the equation. We do this by subtracting "2" from both sides.

This gives us x is greater than -1. So, we can graph:

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>
