A: A number raised to a negative exponent produces the reciprocal of that number. Recall that a reciprocal is just 1 divided by the number. It is very useful to memorize these identities: ______________________________________________________________ Q: How do I evaluate a zero exponent? A: Any number raised . . . → Read More: Negative and Zero Exponents Q: What is an arithmetic sequence? A: An arithmetic sequence is a sequence of numbers in which the difference between successive numbers is constant. The nth term of an arithmetic sequence is given by: where a is the first term and d is the common difference. Q: How do I add radicals like this: ? A: = = Note that this is analogous to 2x + 4x = 6x, where the terms act similar to the variable x. Let’s look at some more examples: = = Q: What if I have to add radicals, but the radicals are different? I am trying to add . A: You can’t add those, or simplify any further without a calculator. You just have to leave it as it is, because the square roots are different (3 and 5). = Let’s look at . . . → Read More: Adding Unlike Radicals Q: How do I subtract radicals like this: ? A: Subtracting radicals is very similar to adding radicals. = = Q: What is the equation of a line? A: The equation of a line is y=mx+b, where m = slope b = yintercept Q: What is slope? A: The slope of a line is a measure of how steep the line is. A larger slope means that the line is steeper, while a smaller . . . → Read More: Equation of a Line Q: The equation of a line is y=2x 7. What is the yintercept? A: It is easy enough to simply compare the equation to the standard form, y=mx+b, and see that b = 7. However, the general way to find the yintercept is to set x=0, and solve for y. y = 2(0) – . . . → Read More: Finding the yintercept Q: Can you show me how to find the slope of a line with the equation (y+3)=5(x2)? A: First, turn the equation into slopeintercept form, y=mx+b. Do this by isolating for y in the equation. y + 3 = 5x – 10 y = 5x – 10 – 3 y = 5x – 13 . . . → Read More: Finding the Slope Q: What is the slope of a line that contains the two points (0,3) and (4,5) ? A: Recall that the equation for slope is: You have two points, (0,3) and (4,5), so you have (x1,y1) and (x2,y2). Put them into the formula: m = (53) / (40) m = 2 / 4 . . . → Read More: Finding the slope between two points
