### What is an example of a solution set?

A solution set is the set of all variables that makes the equation true. The solution set of 2y + 6 = 14 is {4}, because 2(4) + 6 = 14. The solution set of y2 + 6 = 5y is {2, 3} because 22 + 6 = 5(2) and 32 + 6 = 5(3).

**What is an example of one solution?**

This is the normal case, as in our example where the equation 2x + 3 = 7 had exactly one solution, namely x = 2. The other two cases, no solution and an infinite number of solutions, are the oddball cases that you don’t expect to run into very often.

**What is the symbol for no solution?**

symbol Ø

## What is an example of no solution?

When a problem has no solution you’ll end up with a statement that’s false. For example: 0=1 This is false because we know zero can’t equal one. Therefore we can conclude that the problem has no solution. You can solve this as you would any other equation.

### Is 0 0 infinite or no solution?

For an answer to have an infinite solution, the two equations when you solve will equal 0=0 . If you solve this your answer would be 0=0 this means the problem has an infinite number of solutions. For an answer to have no solution both answers would not equal each other.

**What does Z * mean?**

z* means the critical value of z to provide region of rejection if confidence level is 99%, z* = 2.576 if confidence level is 95%, z* = 1.960 if confidence level is 90%, z* = 1.645.

**What does R mean for domain?**

real numbers

## How do you identify real numbers?

The Real Number Line is like a geometric line. A point is chosen on the line to be the “origin”. Points to the right are positive, and points to the left are negative….Any point on the line is a Real Number:The numbers could be whole (like 7)or rational (like 20/9)or irrational (like π)

### What are not real numbers?

Non-real numbers are numbers that contain a square root of a negative number. Typically, the square root of -1 is denoted as “i”, and imaginary numbers are expressed as a multiple of i. Real numbers are all rational and irrational numbers which include whole numbers, repeating decimals and non-repeating decimals.
