Is this equation standard form of an ellipse or circle?-3x^2-3y^2-12x-12y+24=0
What's the center?

Answers

Answer 1
Answer: The standard form equation for a circle is

(h-x)^2+(k-y)^2=r^2

where (h, k) is the center and r is the radius.

The standard form equation for an ellipse is

((x-h)^2)/(a^2)} + ((y-k)^2)/(b^2) = 1

(center h, k and major and minor axes a and b)

This equation is standard form for neither, but might be general form for one.

-3x^2-3y^2-12x-12y+24=0 \n -3(x^2+y^2+4x+4y)=-24 \n x^2+4x+y^2+4y=8\ (complete\ the\ squares)\n (x^2+4x+4)+(y^2+4y+4)=8+4+4\n (x+2)^2+(y+2)^2=16 \n Circle\ with\ radius\ 4\ and\ center\ (2,\ 2)

Remmi wrote the equation of the line y=1/3(x+2) He solved for x and got x=3y-2 Which of the following is an equivalent equation for x?a. x=y-11/3
b. x=y+7/3
c. x=3(y-2/3)
d. x=3(y+2/3)

Answers

Answer:

Option c is correct

x = 3(x - (2)/(3))

Step-by-step explanation:

Remmi wrote the equation of the line :

y = (1)/(3)(x+2)

Multiply both sides by 3 we have;

3y = x+2

Subtract 2 from both sides we have;

3y-2 = x

or

x = 3y-2

We can write this as:

x = 3(x - (2)/(3))

Therefore,  the following is an equivalent equation for x is, x = 3(x - (2)/(3))

Just took the quiz.

The answer is x=3(y-2/3)
