Answer:
Step-by-step explanation:
f(x)/g(x)=(6x+2)/(x-7)
The only restriction upon the domain, possible values of x, is division by zero is undefined. So x cannot equal 7.
So the domain is all real numbers except 7. In interval notation the domain is
x=(-oo, 7),(7, +oo)
Ten percent of 640 is 64.
640/100=6.4
6.4*10=64.
There are many other ways to find this but that is the way I have always used :)
Hope this helps!

The original price minus the sale
You would use the distributive property to solve the equation to remove exponets then to get your final equation.
D
500(x-2)=200x
500x-1000=200x
300x=1000
x=3.333330 or 3 and 1/3
Propeller distance: 3 and 1/3 * 200 = 666.666667 or 666 and 2/3 miles
