Identify the graph of 3x^2+y^2=9 for T(-1,3) and write an equation of the translated or rotated graph in general form.

Archy [21]

ANSWER

D. Ellipse;

$3{x}^{2} +{y}^{2} + 6x - 6y + 3= 0$

EXPLANATION

The given equation is

$3 {x}^{2} + {y}^{2} = 9$

Dividing through by 9 gives

$\frac{ {x}^{2} }{ 3} + \frac{ {y}^{2} }{9} = 1$

This is the equation of an ellipse centered at the origin.

If this ellipse has been translated, so that its center is now at (-1,3), then the equation of the translated ellipse becomes

$\frac{ {(x + 1) }^{2} }{ 3} + \frac{ {(y - 3)}^{2} }{9} = 1$

We multiply through by 9 to get,

$3 {(x + 1)}^{2} + {(y - 3)}^{2} = 9$

Expand to obtain;

$3( {x}^{2} + 2x + 1) + {y}^{2} - 6y + 9 = 9$

Expand to obtain;

$3{x}^{2} + 6x + 3+ {y}^{2} - 6y + 9 = 9$

Regroup and equate to zero to obtain;

$3{x}^{2} +{y}^{2} + 6x - 6y + 3= 0$

I need help with #6 Can u also show work ?

Anit [1.1K]

Answer:

the answer is a when you do the math while b and c and d all keep going bit a stops and can no loneger be changed

Step-by-step explanation:

1. distribute 2 to what is in the parentheses ( you should get x over 3 +10)

2. combine both x over 3

cancel out the x and get 6

your answer wpuld be 6 = 10

Given a right triangle with sides a = 3 , b = 4, and c = 5. Find the missing side c of another right triangle with a = 6 and b =

horsena [70]

c = 10

Step-by-step explanation:

We can find out the missing side of a right triangle by using the Pythagorean theorem.

The Pythagorean theorem is...

$a^2+b^2=c^2$

We can even double check the first problem by plugging in everything into the theorem and solving, everything will come out correct. We can plug in the numbers from the second problem into the theorem and find c, also please note that the hypotenuse of a triangle will always be c. It doesn't matter which you put in for a or b, but since the problem gives us which one is a and which one is b, I'll just be plugging it in like that.

$6^2+8^2=c^2$

$36+64=c^2$

$100=c^2$

A lot of people will stop here and think that the answer is 100, but you need to find the square root of 100, since c is squared. The square root of 100 is 10, so...

c = 10
