Which problem? Which group?

If a line is vertical it only has one x value and it has an infinite amount of y values. The equation for a vertical line is X=b  So, take your x value from you x,y coordinate and plug it in for 'b'   So x=3

Points!!!!!!!   that question should be worth 3 points on a test.

The Mathematicians of the world agreed on a set way to preform the order of operations.  that is just the way it is. P Parentheses first E Exponents (ie Powers and Square Roots, etc.) MD Multiplication and Division (left-to-right) AS Addition and Subtraction...

It is always important to check your answers. For example you have the following problem: If you have x quarters, your mom has 25 quarters. The amount of quarters you have raised to the power of 2 is equal to the amount of quarters your mom has.  How many quarters do you have? the...

Pathagorean Theorem: a^2 +b^2 = c^2   The quadratic formula: ax^2 + bx + c=0

exponentiation is the process of raising a number (or variable) to a power:   ex: 2^2=4, 3^3=9,

3x^2+2x+2= so your goal is to get x by itself you will need to factor this tri-nominal   To learn an easy way to do this follow this method: http://www.youtube.com/watch?v=FxTiogyhwfc

Scientific notation is a useful way to write a large number in short hand. This is only useful when the number you are shortening a large number with several 0's at the end of the number ex: 100 or 10000000 or 4000   to write in scientific notation  you use the format  x*10^n,...

What you need to do is combine "like terms" or numbers with similar variables (letters) So combine all of the x's, y's, and numbers with out letters. an easy way to do this is combine the like terms in parentheses like this: (4x+18x) + (10y-14y) + (3-2) = (22x)...

Well start off with a coordinate grid.  then add the dots and see if it is an acute triangle, obtuse triangle or right triangle. A(0,-6) right 0 units and down 6 units B(3,-6) right 3 units and down 6 units C(3,-2) Right 3 units and down 2 units connect the dots starting with...

So the Matrices are A+2B=C then the first number in A + the first number in B times 2 should = C. So if you are trying to solve for x you need to note that x in in the top right section of the B matrix, so all of the numbers you are going to use will be in the top right section. ...
