Answer:
380
Step-by-step explanation:
171:45=3,8
3,8*100=380
Step-by-step explanation:
You can write an equation of a line conveniently by point-slope form. It's in the form of
where
is the coordinates of a point that's on the line and
is the slope of the line.
Now choose a point (It doesn't really matter which one) and plug that in the equation. I'll choose
where
and ![b = -3](https://tex.z-dn.net/?f=b%20%3D%20-3)
![y -a = m(x -b) \\ y -7 = m(x -(-3)) \\ y -7 = m(x +3)](https://tex.z-dn.net/?f=y%20-a%20%3D%20m%28x%20-b%29%20%5C%5C%20y%20-7%20%3D%20m%28x%20-%28-3%29%29%20%5C%5C%20y%20-7%20%3D%20m%28x%20%2B3%29)
The next thing we have to do now is finding the slope,
, where it's equal to
. I'll make
point 1 and
point 2.
![m = \frac{3 - 7}{3 -(-3)} \\ m = \frac{3 - 7}{3 +3} \\ m = \frac{-4}{6} \\ m = -\frac{2}{3}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B3%20-%207%7D%7B3%20-%28-3%29%7D%20%5C%5C%20m%20%3D%20%5Cfrac%7B3%20-%207%7D%7B3%20%2B3%7D%20%5C%5C%20m%20%3D%20%5Cfrac%7B-4%7D%7B6%7D%20%5C%5C%20m%20%3D%20-%5Cfrac%7B2%7D%7B3%7D)
Now let's plug that to our equation.
![y -7 = m(x +3) \\ y -7 = -\frac{2}{3}(x +3)](https://tex.z-dn.net/?f=y%20-7%20%3D%20m%28x%20%2B3%29%20%5C%5C%20y%20-7%20%3D%20-%5Cfrac%7B2%7D%7B3%7D%28x%20%2B3%29)
Now we have the equation but out of all the choices it seemed that all of them are in slope-intercept form all you have to do now is make our equation rewrite it in slope-intercept form.
![y -7 = -\frac{2}{3}(x +3)\\ y -7 = -\frac{2}{3}x -\frac{2}{3}(3) \\ y - 7 = -\frac{2}{3}x -2\\ y = -\frac{2}{3}x +5](https://tex.z-dn.net/?f=y%20-7%20%3D%20-%5Cfrac%7B2%7D%7B3%7D%28x%20%2B3%29%5C%5C%20y%20-7%20%3D%20-%5Cfrac%7B2%7D%7B3%7Dx%20-%5Cfrac%7B2%7D%7B3%7D%283%29%20%5C%5C%20y%20-%207%20%3D%20-%5Cfrac%7B2%7D%7B3%7Dx%20-2%5C%5C%20y%20%3D%20-%5Cfrac%7B2%7D%7B3%7Dx%20%2B5)
<h3>Answer:</h3>
is your equation.
Answer: y=-2/5x+2
Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2
Answer:
Number of games won by Steelers = 40
Number of games lost by steelers = 8
Step-by-step explanation:
Ratio of wins to losses the Steelers have over the Bengals = 5:1
Total number of games the have played each other in past 15 years = 48
Let number of games won by Steelers be = ![5x](https://tex.z-dn.net/?f=5x)
Let number of games lost by Steelers be = ![x](https://tex.z-dn.net/?f=x)
Total number of games played = ![5x+x=6x](https://tex.z-dn.net/?f=5x%2Bx%3D6x)
So, we have
[Total number of games played]
Dividing both sides by 6.
∴
Number of games won by Steelers = ![5\times 8 = 40](https://tex.z-dn.net/?f=5%5Ctimes%208%20%3D%2040)
Number of games lost by steelers = 8
