Which of the following are possible equations of a parabola that has no real solutions and opens downward?

y > = -(x + 4)^2- 2
y > = -(x + 4)^2 + 2
y > = -x^2 - 2
y > = (x - 4)^2 + 2
y > = -(x - 4)^2- 2

Step-by-step explanation:

A vertex form equation of a parabola is of the form

with vertex at (h,k).

If a parabola opens downwards, then a<0.

If the vertex of such parabola is below the x-axis, then it has no real solution, because it will not intersect the x-axis.

has vertex at (-4,-2), which is below x-axis.

has vertex at (-4,2)--->above x-axis

vertex at (4,-2) ---> below x-axis

(0,-2)----> below x-axis

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
