Answer:

The third X is 6. The fourth Y is 4.5

Step-by-step explanation:

The Rule : X is twice as large as Y. Y is half the size of X.

You can get this piece of information by looking at the different values.

For example, y=1 is x=2. This follows the rule. x=4 is y=2.

We have confirmed the rule is true, now we just need to carry the information into the other blocks!

Best of luck on the quiz! Please give brainliest if I helped you out!

Find the equation of the line of symmetry of y= (x+2)(x-8).

Daniel [21]

Answer:

line of symmetry , x = 3

Step-by-step explanation:

Standard form of quadratic equation is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.

$y = (x+ 2)(x-8)\\\\y = (x^2 -8x + 2x -16)\\\\y = x^2 -6x -16$

a = 1, b = -6, c = -16

Line of symmetry is ,

$x = -\frac{b}{2a} = -\frac{-6}{2} = 3$
