Yes, the equation specifies a function with independent variable x.
Equation: 6x + 19y = 7
This can be put in y = mx + b form,
6x + 19y = 7
19y = -6x + 7
y = -
x + 
Since the equation can be put in the form of a linear function, the domain is all read numbers (-∞,∞) or -∞ < x < ∞ .
Sorry I have to go to baseball bye
1000*(1.06)^8. I'm lazy and don't want to type this into a calculator, but what you get out is the answer.
1 year = 3.6 % depreciation
100-3.6=96.4
so you do 35,865 ×0.964 = 34,573.86
so the price after a year is £34,573.86
to find out what the price is after 10 years you do 34,573.86 (0.964) to the power of 10
which equals £23961.73
I hope that was helpful :)
