Which statements are true for the equation x2 = −4y? check all that apply. the axis of symmetry is x = 0. the focus is at (0, –1). the parabola opens up. the parabola opens right. the value of p = −1. the equation for the directrix is y = 0.

1, 2 and 5 options are correct.

Step-by-step explanation:

Given:

It is a equation of parabola.

It is open downward because coefficient of y is negative.

Vertex: (0,0)

Axis of symmetry, x=0 ( x-coordinate of vertex )

4p=-4

p=-1

Thus, Focus: (0,-1)

Equation of directirx: y=1

Hence, The correct options are

The axis of symmetry is x = 0.

The axis of symmetry is x = 0.

The value of p = −1.

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial
