If they are all in a line then we can find the equation of their line using: y = mx + b
First find m using points (2,5) and (3,3)
m = (5-3)/(2-3) = 2/-1 = -2
Now using (3,3) and m= -2 to solve for b:
3 = -2(3) + b
3 = -6 + b
9 = b
So our equation is y = -2x + 9
That is the solution for question b)
Now to find the mystery point, solve:
1 = -2x + 9
-8 = -2x
4 = x
So our mystery point is (4,1)
So for part a) the answer is k = 4
Answer:
Step-by-step explanation:
Sum
132 + 8 = 140
Divide
140 ÷ 36 = 3.8
Round to integers

Answer:
The cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
Step-by-step explanation:
Let us assume this is a simple interest scenario.
Let D be the cost of desktop
Let L be the cost of laptop
Given- the laptop cost $150 more than the desktop.
So,
The total finance charge for 1 year is given by :

Substituting the value of L here, we get;

=>
=> 
=> 
=> 
D = $1750
As
So, 
L = $1900
We can check this :

=> 
=> 
So, the cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
