Step-by-step explanation:
Answer: y=1,5x-8
Step-by-step explanation:
At first transform the equation
2x+3y=18
3y= 18-2x
y= 6 - (2/3)x
The linear function has general form, which looks like that:
y=mx+n
perpendicular means that m1*m2=-1
In our case m1= -(2/3) and m2 is unknown
(-2/3)*m2= -1
m2=3/2 so m2=1,5
The line has to go through the point (6,1)
so 1=6*1,5+n
1=9+n
n= -8
so the function looks like that y=1,5x-8
A. f(t)=9000-1000t; Since 9000 is the number we start on, that is written as the constant. And since the value decreases by $1000 each year, we can put the $9000 it costs currently and will decrease by $1000 per year (t), this can be written as the function f(t)=9000-1000t
B. $6000; Just plug 3 into the equation to find the answer.
f(t)=9000-1000(3)
f(t)=9000-3000
f(t)= 6000
It costs $6000 after three years
C. $3500; To solve this just subtract 500 from 9000 to get 8500, and plug this in as the constant in our function.
f(t)=8500-1000(5)
f(t)=8500-5000
f(t)=3500
The answer is $3500
