Answer:
{x,y} = {1/3,1/9}
Step-by-step explanation:
Solution :
{x,y} = {1/3,1/9}
System of Linear Equations entered :
[1] 4x + 6y = 2
[2] -4x + 3y = -1
Graphic Representation of the Equations :
6y + 4x = 2 3y - 4x = -1
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 3y = 4x - 1
[2] y = 4x/3 - 1/3
// Plug this in for variable y in equation [1]
[1] 4x + 6•(4x/3-1/3) = 2
[1] 12x = 4
// Solve equation [1] for the variable x
[1] 12x = 4
[1] x = 1/3
// By now we know this much :
x = 1/3
y = 4x/3-1/3
// Use the x value to solve for y
y = (4/3)(1/3)-1/3 = 1/9
Solution :
{x,y} = {1/3,1/9}

<u>Step-1: Find the data.</u>
- 70's: 1
- 80's: 1
- 90's: 2
- 100's: 3
- 110's: 4
- 120's: 4
- 130's: 2
- 140's: 1
Data obtained (Smallest to biggest):
- 70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140
<u>Step-2: Count the number of digits.</u>
<u>Step-3: Use the formula "Total digits/2".</u>
The 9th digit in the data is the median.
<u>Step-4: Revise the data.</u>
- 70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140
The median value of the line plot is 110.
x<-3,or x>3
only A and B satisfy the given condition.
