What is the difference between a rational and an irrational?
A rational number is one that can be represented as an integer or a fraction with an integer over an integer. An irrational number cannot be represented using integers. Examples of rational numbers: 2, 100, 1/2, 3/7, 22/7 Examples of irrational numbers: π, e, √2
What is the slope of the line represented by the equation y equals 7?
The graph of [ y = 7 ] is a straight horizontal line, passing through the point [ y = 7 ]on the y-axis. The slope of a horizontal line is zero.
What is 2 over 7 plus 1 over 2?
7 over 12
What is the multiplicative inverse of 2 over 7?
It is 7 over 2 or 3.5
How can you tell if a point will be on a graph by looking only at the equation?
Substitute the point into the equation, eg. if you have point (1,2) and equation y=3x+7 you get 2=3*1+7 =10 2 doesnt equal 10, so (1,2) isn't on the graph y=3x+7
What are the characteristics of a straight line graph?
Usually, the basic graphing formula is (y=mx+b). The fraction represented by the letter "m" must equal "1" (that is, 2/2 or 7/7). This way, the line moves in a straight line across the graph.
How do you graph y plus 2 equals 7?
The equation you have given, y + 2 = 7, does not describe a line, it describes the number 5. You would not graph a single number, there is nothing to graph.
Is 1 and 2 sevenths rational?
Yes a rational number is one which can be represented by one integer over another (possibly the same) integer which cannot be zero. 1 2/7 = (1×7+2)/7 = 9/7 (as an improper fraction) 9/7 is one integer over another integer, so it is a rational number.

What is the lagest decimal number that can be represented with 7 bits?
It is 127 = 2^7 - 1
What is 2 over 7 plus 3 over 7?
2 over 7 + 3 over 7= 5 over 7
What is 2 over 7 - 4 over 7?
negative 2 over 7
What is 4 over 7 subtracted from 2 over 7?
2/7 - 4/7 = -2/7
What is 9 over 7 as a mixed number?
Since 7 < 9 the fraction cannot be represented as a mixed number.
What is 21 over 6 in simplest form?
2 over 7 2/7
If one part of a circle graph is 5 over 7 and the other is 1 over 14 what is the final piece?
3 over 14
