By now, either you are able to correctly answer enough questions, or you are not.  No last-minute cramming will change that significantly.  Better to concentrate and put your energy into what you can control:  staying clean and sober, being in healthy physical condition, being...

Looks like a "trick problem" to me... I'll take a wild stab here... :-)    If we make the vertical (y) axis be h (time in hours), and the horizontal (x) axis be d (distance in miles), then the h-intercept of 800 would be when d=0, presumably J's initial distance from Woods...

Eyes + glasses means that he watches over everything that goes on around in the valley.  His glasses have yellow rims which symbolize being corrupt, in two different ways:  all he sees is corruptness, and he sees through the eyes of someone who is corrupt.

Another way to see why this is true: try dividing by a very small number. For example: 2/0.001 = 2000. Now make that denominator even smaller: 2/0.0001 = 20,000. And smaller: 2/0.0000001 = 20,000,000. As you can probably tell by now, as the denominator gets smaller and shrinks towards zero,...

Hi Nunii,  First let's look at the similar-looking equation y=2x-1.  This is in the y=mx+b form, and we know we have a straight line with a slope (m) = +2, and when x=0, the line crosses the y axis at -1, just below the x-axis.  By trying a few other values for x, we can...

Associative, because it doesn't matter which comes first.  If we let (m+n) = x, then we'd have x*p = p*x, where the order obviously doesn't matter. After you multiply p times m+n, we have mp + np = pm + pn, which is called Distributive, because we are "distributing"...

Hi Kasey!  Just think something like, "I need to collect all the terms that look similar all together."  In this case, 40r and 63r both look similar, because they both have the letter r, and the other terms don't.  And since the other two terms, -22 and -91 (don't forget...

13x-3=4x-4 (answer)

There's really only one way to solve this: 13x - 3 = 4x - 4 13x - 4x - 3 = 4x - 4x -4  (subtract 4x from both sides to get all x's on the same side) 9x -3 = -4 9x -3 +3 = -4 +3   (add 3 to both sides, to get x's alone) 9x = -1 9x/9 = -1/9  (divide both...

Hi Jessi... The whole idea of using the two columns is to help you think of each step to use when "proving" why something is true (or not). As a simple example:  if we draw two intersecting lines, like a large X, we form 4 angles around the intersection (where the lines meet)...

By definition, in statistics, survey methodology studies sampling individuals from a population to make statistical inferences about the population using the sample, so the answer is survey.

v^2-6v=-91 (answer)

To complete the square:  we put the equation into the form ax2+bx+c = 0, or ax2+bx=-c, which is what we have with v2-6v=-91.  the "a" in this case = 1, the "b" = -6, and c = 91.  We can divide b by 2 (b/2) and add that to both sides of the equation...

Factor our what's common to all (both terms):  x (x2 - 36).  x * x = x2.  Now what times what = 36, or what is the √36?  6 x 6 = 36, and +6 x -6 = -36.   So now we have x (x+6) (x-6)

Rizul is correct - here's what it looks like: (4.2 * 1.5) (103 * 106) = 6.3 * 109.  Exponents simply add when you multiply Example:  22 = 4 (2*2), and 23 = 8 (2*2*2) 4 * 8 = 32;  so does 22 * 23      (2*2)(2*2*2) = 32 If you have an exponent raised...

You may recognize this form of equation:  y=mx+b is the standard slope-intercept form, where m = the slope, or tilt, of the line when graphed, and b = the y-intercept - the value of y when that graphed line crosses the y (vertical) axis (when x = 0). Just like any other equation, we...
