Answer:
Tiff, hon, just measure a window, your wasting your time
Step-by-step explanation:
![f(x)=2x^2-4x+1](https://tex.z-dn.net/?f=f%28x%29%3D2x%5E2-4x%2B1)
Substitute the values of x to the equation of the function f:
![x=-1\to f(-1)=2(-1)^2-4(-1)+1=2(1)+4+1=7\\\\x=2\to f(2)=2(2^2)-4(2)+1=2(4)-8+1=1](https://tex.z-dn.net/?f=x%3D-1%5Cto%20f%28-1%29%3D2%28-1%29%5E2-4%28-1%29%2B1%3D2%281%29%2B4%2B1%3D7%5C%5C%5C%5Cx%3D2%5Cto%20f%282%29%3D2%282%5E2%29-4%282%29%2B1%3D2%284%29-8%2B1%3D1)
Therefore we have two points (-1, 7) and (2, 1).
We can calculate the slope of line l.
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Substitute:
![m=\dfrac{1-7}{2-(-1)}=\dfrac{-6}{3}=-2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B1-7%7D%7B2-%28-1%29%7D%3D%5Cdfrac%7B-6%7D%7B3%7D%3D-2)
<h3>Answer: A) -2.</h3>
Answer:
The total number of students in a survey is 300.
Let the number of junior male(JM) be x and the number of senior males(SM) be y.
Let the number of junior female(JF) be p and the number of senior males(SF) be q.
It is given that there are 160 males, 80 junior females, 130 seniors.
Since number of males are 160. So the number of females are,
![300-160=140](https://tex.z-dn.net/?f=300-160%3D140)
Since number of junior females is 80.
![JF+SF=140\\80+SF=140\\SF=60](https://tex.z-dn.net/?f=JF%2BSF%3D140%5C%5C80%2BSF%3D140%5C%5CSF%3D60)
Since number of seniors are 130.
![SM+SF=130\\SM+60=130\\SM=70](https://tex.z-dn.net/?f=SM%2BSF%3D130%5C%5CSM%2B60%3D130%5C%5CSM%3D70)
Since number of males is 160.
![JM+SM=160\\JM+70=160\\JM=90](https://tex.z-dn.net/?f=JM%2BSM%3D160%5C%5CJM%2B70%3D160%5C%5CJM%3D90)
Therefore, the table and venn diagram is shown below.
Answer:3/7
Step-by-step explanation:
3 * 1/7 is
3 * 1 = 3
Divided by 7 = 3/7
There’s nothing to simply, as that fraction cannot be reduced
Answer:
1. c
2. a
3. d
4. b
Step-by-step explanation:
For 1, use parchment paper for rotating it around the origin.
For 2, just make the y value positive.
For 3, add 13 to the y value.
For 4, use process of elimination with the answer choices.
(I know right, horrible explanation but you wanted the answers right?)
