Answer:
1,700
Step-by-step explanation:
The computation of the initial value of the computer is shown below:
Let us assume the value of a certain computer in the first year is X
In the second year, it is 
In the third year, it is 
In the fourth year, it is 
Now it is given that after 3 years, the value of the computer is = 425 i.e equal to

So, X = 1,700
Hence, the initial value of the computer is 1,700
What you do is you put three on top because a=3 and then you add 5 and 3 to get 8 for the bottom and you get a answer of 3/8 which you cannot simplify with whole numbers
Answer:
4x12= 48. So what option gives you 48?
Step-by-step explanation:
Give the options

So, there are (3)(4)(2)=24 positive factors.
Put them into y=mx+b
y=1/3x -1
y=2/3x-4
Graph them. Where they touch is your answer. No touch? No solution. Same line? Infinite solutions.
Second set: Same thing.
Solution to first set is (9,2)
