Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting
Deffense [45]

Point F is on line a, so it does represent Josiah's distance at a certain time. Also, point F is below line b, so it represents a distance that is less than Chana's distance. This is a distance-time graph problem.

<h3>What is the proof for the above?</h3>

Recall that Josiah had a head start of 10 meters and he skates at 2 meters per second.

Since Y is the function that represents the distance in meters from the finished line, by observation, it is clear to see that all the factors that are related to his race are adequately represented in:

y = 10 + 2x

Where 10 is the head start in meters

2 is the rate at which he skates per second; and

x is the unknown amount of time in seconds.

Given that the point F sits over 25 seconds,

that is F(y) = 10 + 2 * 25

= 60 meters.

Hence, Point F is on line a, so it does represent Josiah's distance at exactly 25 seconds.

(x+9)(x+2) expand and simplify
klio [65]

We are given the following expression and want to expand it and simplify it.

(x+9)(x+2)

Use the FOIL method for expanding

=x^2+9x+2x+(9\times2)

Simplify

=x^2+11x+18

Let me know if you have any questions or need clarifications, thanks!
