Answer:

choose B. 54 meters/second, it is closest to my calculation of 55 meters/sec

Step-by-step explanation:

To find average speed between 3 and 8 seconds, find the total distance traveled during that time.

650 meters at 3 seconds

to 375 meters at 8 seconds

then average speed = ( 650 - 375 ) / (8 - 3) = 275 /5 = 55 meters /sec

I need help with number 13

nikklg [1K]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

We have the point (0, 5). Therefore b = 5.

We have: y = mx + 5

Other point (3, 2). Substitute the coordinates of the point to the equation of the line:

$2=3m+5$ <em>subtract 5 from both sides</em>

$-3=3m$ <em>divide both sides by 3</em>

$-1=m\to m=-1$

<h3>Answer: f(x) = -1x + 5 = -x + 5</h3>
