F(x) = 2/3x + 1
This is in the slope-intercept form of an equation for a line.
Which is written as this: (Note f(x)= is the same as saying y= in this case)
y = mx + b
M is our slope. Slope is the RISE over the RUN
In other words it is y/x
For this graph y represents distance, and x represents time. (Life Tip: TIME is almost ALWAYS the X value)
In this case M = 2/3
So her speed is:
2 units/3 units
B is the y-intercept. The y-intercept is where the X-value equals 0. So, (0,y). Because the y-intercept is distance she should have a y-intercept of 0. (The origin) because that would mean at the start of the race she had no distance (aka she was at the starting line).
Because her y-intercept (b) = 1 she did have a head start.
Here are both the answers at once to make it easier for you:
Speed (Replace Units with whatever units you were given. Distance Units go on top. Time units on bottom. Example: Meters/Second))
2 units/3 units
Did she have a head start? (Unit being whatever distance unit you were given)
Yes, 1 unit.
The answer is B because the LCM of 8 and 9 is 72, which changes 4 5/8 to 4 45/72 and 2 2/9 to 2 16/72. 45/72+16/72 is 61/72 and then add the whole numbers.
Answer:
an out-of-order sequence can't result in any player prematurely gaining information that would reasonably affect decisions later in that sequence.
