Answer:

x = 5

Step-by-step explanation:

1. Expand

    8x - 5x + 5 = 20

2. Simplify

    3x + 5 = 20

3. Subtract 5 from both sides

    3x = 20 - 5

4. Simplify

    3x = 15

5. Divide both sides by 3

    x = 15/3

6. Simplify

    x = 5

Morgarella [4.7K]

Step-by-step explanation:

Show Solution. Start by writing the equation of the parabola in standard form. The standard form that applies to the given equation is (x−h)2=4p(y−k) ( x − h ) 2 = 4 p ( y − k ) . Thus, the axis of symmetry is parallel to the y-axis.
