Answer:

x = -11/9

Step-by-step explanation:

7(x+3)=-2(x-5)

Distribute

7x+21 = -2x+10

Add 2x to each side

7x+21 +2x = -2x+10+2x

9x +21 = 10

Subtract 21 from each side

9x +21-21 = 10-21

9x = -11

Divide each side by 9

9x/9 = -11/9

x = -11/9

What is the equation of the parabola, in vertex form, with vertex at (-2,-4) and

Arlecino [84]

Answer:

Step-by-step explanation:

The distance between the vertex and the directrix is 4 units, that means that p = 4 in the equation

$(y-k)^2=4p(x-h)$ and h and k are the coordinates of the vertex. Filling in:

$(y+4)^2=4(4)(x+2)$ which simplifies to

$(y+4)^2=16(x+2)$ choice C
