Determine if the solution set for the system of equations shown is the empty set, contains one point or is infinite. 3x + 2y = 6
Elanso [62]

The solution set for the system of equations contains one point

The system of the equations has one solution

Step-by-step explanation:

The system of the linear equations has:

  • 1 solution if the 2 lines that represent the equations intersect each other in one point
  • No solution "{}" if the 2 lines that represent the equations are parallel
  • Infinite solutions if the 2 lines that represent the equations are coincide (same line)

→ Intersected lines have different slopes

→ Parallel lines have same slopes and different y-intercepts

→ Coincide lines have same slopes and same y-intercepts

Let us put each equation in the form y = m x + c, where m is the slope

and c is the y-intercept

∵ 3x + 2y = 6

- Subtract 3 x from each side

∴ 2y = 6 - 3 x

- Divide both sides by 2

∴ y = 3 - 1.5 x

∴ y = -1.5 x + 3

∵ y = m x + c

∴ m = -1.5 and c = 3

∵ x - y = 2

- Subtract x from both sides

∴ -y = 2 - x

- Divide both sides by -1

∴ y = -2 + x

∴ y = x - 2

∵ y = m x + c

∴ m = 1 and c = -2

∵ The two equations have different slopes

∴ The two line are intersected in a point

∴ The system of the equations has one solution

The solution set for the system of equations contains one point

The system of the equations has one solution

A track coach records the number of miles that he ran per day over the month. The stem-and-leaf plot below summarizes this data.
Alenkinab [10]

Answer:

Mean = 6.70

Step-by-step explanation:

Given

See attachment for plot

Required

The mean of the plot

Mean is calculated as:

Mean = \frac{\sum x}{n}

Where

n = 20

Using the given key to read, the plot;

We have:

Mean = \frac{3.00+3.25+4.25+5.00+..........+8.75+9.50}{20}

Mean = \frac{134.00}{20}

Mean = 6.70
