Answer:
The slope is 13.
The x intercept is
.
The y intercept is
.
Step-by-step explanation:
1. Finding the slope.
This is a linear equation, because <u>it's graph forms a line</u>. In a linear equation, the slope is always the value that multiplies x. In this case, x is being multiplied by 13, therefore, <u>the slope is 13</u>.
2. Finding the x intercept.
The x intercept is found when the value of y is 0. Let's replace the value of y for 0 in the equation and solve the x:
![13x-y + 12 = 0\\\\13x-(0) + 12 = 0\\\\13x+12 = 0\\\\13x= -12\\\\x=\frac{-12}{13}](https://tex.z-dn.net/?f=13x-y%20%2B%2012%20%3D%200%5C%5C%5C%5C13x-%280%29%20%2B%2012%20%3D%200%5C%5C%5C%5C13x%2B12%20%3D%200%5C%5C%5C%5C13x%3D%20-12%5C%5C%5C%5Cx%3D%5Cfrac%7B-12%7D%7B13%7D)
<u>The x intercept is </u>
<u>.</u>
3. Finding the y intercept.
The y intercept is found when the value of x is 0. Let's replace the value of x for 0 in the equation and solve the y:
![13x-y + 12 = 0\\\\13(0)-y + 12 = 0\\\\-y + 12 = 0\\\\-y=-12\\\\y=12](https://tex.z-dn.net/?f=13x-y%20%2B%2012%20%3D%200%5C%5C%5C%5C13%280%29-y%20%2B%2012%20%3D%200%5C%5C%5C%5C-y%20%2B%2012%20%3D%200%5C%5C%5C%5C-y%3D-12%5C%5C%5C%5Cy%3D12)
<u>The y intercept is </u>

Answer:
<u>The correct answer is that the average speed of Usain Bolt in 2009 was 10.42 meters per second.</u>
Step-by-step explanation:
<u>1. Let's check the information given to resolve the question:
</u>
World Record time of Usain Bolt = 9 seconds 3/5
Distance = 100 meters
Find his average speed in meters per second
<u>2. Let's find the average speed of Usain Bolt in 2009:</u>
World Record time of Usain Bolt = 9 seconds 3/5 = 9.6 seconds (3/5 = 0.6)
World Record time of Usain Bolt = Distance / World Record time
World Record time of Usain Bolt = 100 meters /9.6 seconds
World Record time of Usain Bolt = 10.416666 meters per second
World Record time of Usain Bolt = 10.42 meters per second (Rounding to two decimal places)
<u>The correct answer is that the average speed of Usain Bolt in 2009 was 10.42 meters per second.</u>
Answer:
Hi so you have the answer
Say you have 1.23 if the last digit is under 5 it would be 1.20
Now say you have 3.47 if the last digit is above 5 it would be 3.50
If it is something like 4.45 the 5 is the last digit so it would be 4.50
Step-by-step explanation:
um hope this helped :)
P(1) = 1/6 = 0.166666 = 16.7%
P(2) = 1/6 = 0.166666 = 16.7%
P(3) = 1/6 = 0.166666 = 16.7%
P(4) = 1/6 = 0.166666 = 16.7%
P(5) = the same as the 4 above.
P(6) = the same thing as those numbered P(1) to P(4)
You might wonder how I got the %
any decimal expressed as a percent means multiply the decimal by 100.
0.1666666 * 100 = 16.66666 % which I rounded to 16.7%
