User: Which of the following equations is of an ellipse with x-intercepts of (3, 0) and (-3, 0) and y-intercepts at (0, 1) and (0, -1)?

Weegy: no slope means m = 0 in y = mx + b line through (- 3, 0) is y - 0 = 0(x + 3) Or y = 0

User: The volume of a box(V) varies directly with its length(l). If a box in the group has a length of 30 inches and k = 24, what is its volume?

Weegy: 3) Complete the following item based on the given information. [ The volume of a box(V) varies directly with its length(l). V = kl If one of the boxes has a volume of 325 cubic inches and a length of 13 inches, what is the constant of proportionality for the group of boxes? k = 325/13 = 25 ]

User: The volume of a box(V) varies directly with its length(l). If a box in the group has a length of 30 inches, and the girth of 20 inches (perimeter of the side formed by the width and height), what is its height? Use k = 24. (Hint: Volume = length width height. Solve for length, and substitute into the equation for constant of proportionality.)

Weegy: D. 3.75.

The equation of an ellipse with x-intercepts of (3, 0) and (-3, 0) and y-intercepts at (0, 1) and (0, -1) is x^2/3^2 + y^2/1^2 = 1 or x^2 + 9y^2 = 9.

The correct conic section to fit the equation 49x^2 - 16y^2 = 784 is Hyperbola.
49x^2 - 16y^2 = 784
divided by 784 on both sides the result is:
x^2/16 - y^2/49 = 1
x^2/4^2 - y^2/7^2 = 1 which is the equation for hyperbola.

x^2 - y = 3
x - y = -3
The first equation - the second equation the result is:
x^2 - x = 6
x^2 - x - 6 = 0
(x - 3)(x + 2) = 0
x = 3 or x = -2
when x = 3,
3 - y = -3, y = 3 + 3 = 6;
when x = -2,
-2 - y = -3, y = -2 + 3 = 1.
The solution for the equation system x^2 - y = 3, x - y = -3 is {3, 6}, {-2, 1}
