Answer:
a) ![f(x) = 45300 + 143x](https://tex.z-dn.net/?f=f%28x%29%20%3D%2045300%20%2B%20143x)
In which 45300 is the current number of miles driven and 143 is the amount of miles she drives each day.
b) 47,016 miles.
Step-by-step explanation:
Question a:
Every day when commuting to and from work, Stefanie drives her car a total of 143 miles for 2.5 hours. Her car already has 45,300 miles on it.
So, after x days of work, the amount of miles driven will be given by
![f(x) = 45300 + 143x](https://tex.z-dn.net/?f=f%28x%29%20%3D%2045300%20%2B%20143x)
In which 45300 is the current number of miles driven and 143 is the amount of miles she drives each day.
Question b:
After 4*3 = 12 days of work. So
![f(12) = 45300 + 143*12 = 47016](https://tex.z-dn.net/?f=f%2812%29%20%3D%2045300%20%2B%20143%2A12%20%3D%2047016)
47,016 miles.
Answer:
2 squads of five can be picked from 10 basketball players
Step-by-step explanation:
To solve this problem you have to divide 10 ÷ 2 which equals to 5.
For this case we have that the original vertex is given by:
P = (4, -5)
We apply the following transformation:
(x, y) (-x, y)
We have then:
(4, -5) (- (4), -5) (- 4, -5)
Therefore, we have a reflection on the y axis.
The point obtained is the vertice:
P '= (-4, -5)
Answer:
the line of reflection is:
the y-axis
-1.5(4-n)+2.8
multiply 4-n by -1.5
multiply to both the 4 and -n
-6+1.5n+2.8
add -6+2.8 since they are similar
-3.2+1.5n
1.5n-3.2
I believe this is the simplest form
