Answer:

The answer you get is x=-3, and y=5 or (-3,5)

Step-by-step explanation:

3x+y=-4 and 5x-2y = -25.

Firstly,  to solve the equation let's use the multiplication method.

5x-2y=-25 (Multiply by 1)

3x+y=-4     (Multiply by 2)

=

5x-2y=-25

+6x+2y=-8

=

11x=-33

x=-3

We know that x=-3, now we can find y by substituting this value into other equations.

5(-3)-2y=-25

-15-2y=-25

+15      +15

-2y=-10

y=5

The answer you get is x=-3, and y=5 or (-3,5)

A parabola is defined by the equation x2 = 3/4 y. In which direction will the parabola open?
TEA [102]
The equation of parabola is x^2=\dfrac{3}{4}y. 
The canonical equation of parabola is y^2=2p x and this parabola has branches that go in positive direction of x-axis.

Since in your equation x is changed to y and y to x, then the <span>branches of the parabola go in positive y-axis direction, the vertex is placed at the origin.
