The correct answer is: x ≥1
The median is going to be 75 since it is in the middle of the box.
Answer:
![\huge\boxed{y=-\frac{1}{7}x+ 10}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7By%3D-%5Cfrac%7B1%7D%7B7%7Dx%2B%2010%7D)
Step-by-step explanation:
In order to find the equation of this line, we need to note two things.
- A) The slope of two lines that are perpendicular will be opposite reciprocals (that is, multiplying them gets us -1.)
- B) We can substitute a point inside an incomplete equation to try and find a missing value.
So first, let's find the opposite reciprocal of 7 which will be the slope to this equation.
- <u>Reciprocal of 7:</u>
- <u>Opposite of </u>
:
So the slope of this line will be
. The y-intercept will change, and we can substitute what we know into the equation
.
![y = -\frac{1}{7}x+b](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B1%7D%7B7%7Dx%2Bb)
Now, we can substitute a point on the graph (14, 8) into this equation to find b.
Now that we know the y-intercept, we can finish off our equation by plugging that in.
![y = -\frac{1}{7}x + 10](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B1%7D%7B7%7Dx%20%2B%2010)
Hope this helped!
okay lets foces on question 20. 3/20
all you need to do is times the dinominator into 100 so 20x5=100 and now you have to multipy the same number that you multiplyed the first one by so 3x5=15 so the anwer would be 15/100 and to put that in a decimal you need to see the number on top witch is 15 so your real ANWSER IS .15
