An elliptical equation is in the form
Ax^2+Bx+Cy^2+Dy+E=0
the equation is a Hyperbola. When x and y are both squared, and exactly one of the coefficients is negative and exactly one of the coefficients is positive.
1-49x^2-98x-64y^2+256y-2831=0
2-4x^2+32x-25y^2-250y+589=0
3-81x^2+512x-64y^2-324y-3836=0

Answer: The required equations of hyperbolas would be

49x^2-98x-64y^2+256y-2831=0\\\\4x^2+32x-25y^2-250y+589=0\\\\81x^2+512x-64y^2-324y-3836=0

Step-by-step explanation:

Since we know that

The general equation for a conic section:

Ax^2+Bxy+Cy^2+Dx+Ey+F=0

In case of hyperbola, we get that

Discriminant=B^2-4AC>0

According to this, both x and y are squared.

And one of the coefficient of x and y must be positive and one of the coefficient of x and y must be negative.

So, the required equations of hyperbolas would be

49x^2-98x-64y^2+256y-2831=0\\\\4x^2+32x-25y^2-250y+589=0\\\\81x^2+512x-64y^2-324y-3836=0

Solve for x. 1/2x + 3 = 2/3x + 1
makvit [3.9K]

Answer:

x = 12

Step-by-step explanation:

\frac{1}{2} x + 3 = \frac{2}{3} x + 1

multiply through by 6 ( the LCM of 2 and 3 ) to clear the fractions

3x + 18 = 4x + 6 ( subtract 3x from both sides )

18 = x + 6 ( subtract 6 from both sides )

12 = x

How do i write 5,972,000,000,000,000,000,000,000kg in Scientific Notation
never [62]
In order to write this in scientific notation, we must move the decimal from the beginning all the way to between the 5 and the 9
Note: you can move the decimal anywhere you want but typically scientific notation will have the decimal in between the first and second digit.

Since we move the decimal 24 digits to the right, our answer will be

5.972 * 10^24
or
5.972E24

Hope this helps!!
