If n is 2, you substitute 2 for n and multiply 5(2)+8= 10 +8 = 18
Answer:
The correct option is C.
Step-by-step explanation:
From the given figure it is noticed that the coordinates of B are (-5,-7).
If ABC is reflected across x = 1, then
![(x,y)\rightarrow(1-(x-1),y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%281-%28x-1%29%2Cy%29)
![(x,y)\rightarrow(2-x,y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%282-x%2Cy%29)
![(-5,-7)\rightarrow(2+5,-7)](https://tex.z-dn.net/?f=%28-5%2C-7%29%5Crightarrow%282%2B5%2C-7%29)
![(-5,-7)\rightarrow(7,-7)](https://tex.z-dn.net/?f=%28-5%2C-7%29%5Crightarrow%287%2C-7%29)
If ABC is reflected across y =-3.
![(x,y)\rightarrow(x,-3-(y-(-3)))](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%28x%2C-3-%28y-%28-3%29%29%29)
![(x,y)\rightarrow(x,-6-y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%28x%2C-6-y%29)
![(7,-7)\rightarrow(7,-6-(-7))](https://tex.z-dn.net/?f=%287%2C-7%29%5Crightarrow%287%2C-6-%28-7%29%29)
![(7,-7)\rightarrow(7,1)](https://tex.z-dn.net/?f=%287%2C-7%29%5Crightarrow%287%2C1%29)
Therefore option C is correct.
Answer:
Step-by-step explanation:
Given that Of 450 college students, 110 are enrolled in math, 205 are enrolled in English, and 50 are enrolled in both. If a student is selected at random
the probability
(a) The student is enrolled in mathematics=![\frac{110}{450} =0.244\\](https://tex.z-dn.net/?f=%5Cfrac%7B110%7D%7B450%7D%20%3D0.244%5C%5C)
(b) The student is enrolled in English.=![\frac{205}{450} =0.456\\](https://tex.z-dn.net/?f=%5Cfrac%7B205%7D%7B450%7D%20%3D0.456%5C%5C)
(c) The student is enrolled in both.=![\frac{50}{450} =0.111\\](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B450%7D%20%3D0.111%5C%5C)
(d) The student is enrolled in mathematics or English.=![\frac{110+205-50}{450} =0.589\\](https://tex.z-dn.net/?f=%5Cfrac%7B110%2B205-50%7D%7B450%7D%20%3D0.589%5C%5C)
(e) The student is enrolled in English but not in mathematics.
=![\frac{205-50}{450} =0.344\\](https://tex.z-dn.net/?f=%5Cfrac%7B205-50%7D%7B450%7D%20%3D0.344%5C%5C)
(f) The student is not enrolled in English or is enrolled in mathematics.
=![\frac{450-205+110}{450} =0.7889\\](https://tex.z-dn.net/?f=%5Cfrac%7B450-205%2B110%7D%7B450%7D%20%3D0.7889%5C%5C)
I believe that it would be the first one. They are looking for the distance from the y-axis, so the x value doesnt matter. 6 is 6 units away from the y-axis, and -6 is also 6 units away from the y-axis. Hope I helped!
