Answer:

x = -2

Step-by-step explanation:

a parabola is symmetric (has a mirror image)

a parabola has ONE vertex (a highest or lowest point).

thus a line that goes through the vertex is it's axis of symmetry.

x = 5 , x=99, x=102 are vertical lines that intersect the x axis no matter what the y value is....

your axis of symmetry is a line that looks like X= SOMETHING

the "something" is the X value of the vertex, which is (-2,3)

this the equation x = -2 is the answer ... see the image

This baseball season, Barry gets two hits for every 16 at bats. This statement represents his batting average.

Katen [24]

Answer:

A. 1/8 or 0.125

B. No

Step-by-step explanation:

A. The batting average formula is: (# of hits) ÷ (# of at-bats).

Here, we see that Barry has 2 hits and 16 at-bats, so plug these numbers into the formula:

(# of hits) ÷ (# of at-bats)

2 ÷ 16 = 1/8 = 0.125

B. Batting average is always rounded to the thousandths place; in other words, we only calculate the number up to the third decimal place.

Looking at our batting average calculated in part A, it's 0.125, which is already at the third decimal place, and we can see that there is clearly no 0 at the end. So, the answer is no.
