five-year-old students at an elementary school were given a 30-yard head start in a race. the graph shows how far the average student ran in 30 seconds.

which statement best describes the domain of the function represented in the graph?

a. 5 ≤ x ≤ 60, or x is from 5 to 60
b. 5 ≤ x ≤ 30, or x is from 5 to 30
c. 30 ≤ x ≤ 60, or x is from 30 to 60
d. 0 ≤ x ≤ 30, or x is from 0 to 30

The domain is the x value of a function/ graph.

The horizontal line would be the X value. The line starts at 30 and ends at 60,

So the answer would be:

C. 30 ≤ x ≤ 60, or x is from 30 to 60

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
