Answer:
8
Step-by-step explanation:
This is because the expression is already in decimal form
Answer:
Option B. $900
Step-by-step explanation:
Let
y ----> the value of the car
x ----> the time in years
we know that
The linear function in slope intercept form is equal to

where
m is the slope or the depreciation rate
b is the y-intercept or initial value of the car
we have
The y-intercept or initial value is equal to


we have the ordered pair (5,500)
substitute the value of x and the value of y of the ordered pair in the linear equation and solve for m


Is negative because is a decreasing function
The linear equation is equal to

therefore
It would depreciate $900 each year.
Answer:
x=2 , y=6
Step-by-step explanation:
3 x + 2 y = 18
3 x + y = 12
(-) (-) (-)
-------------------------------------------
y = 6
3x+6=12
=>3x=12-6
=>3x=6
=>x=6/3
=>x=2
