Answer:

1) x = 4

2) a square root cannot be equal to a negative value

Step-by-step explanation:

1) add 1 to each side

2) square each side

(√2x + 1)² = 3²

2x + 1 = 9

2x = 8

x = 4

2) subtract 4 from each side

√2x + 1 ≠ -5

What is the equation of a parabola with vertex (0, 0) and directrix x = -3.

miv72 [106K]

Answer:

${y}^{2}= 12x$

Step-by-step explanation:

The standard equation of a parabola with vertex at the origin and and directix x=-p is of the form

${y}^{2} = 4{p}x$

Where p is simplify the distance from the origin to the directrix.

That is

$p = 3$

${y}^{2} = 4 \times 3x$

This simplifies to

${y}^{2}= 12x$
