A store manager is marking down chess boards from $25 to $14. What percentage is the discount?
Alborosie
Remember: when calculating percent it will always be over 100. With the given numbers 14 is your part out of the total (25). It should be written as part/whole.

As previously said, the percent is always over 100. (x/100)

In this problem you are given the part (14) and the whole (25). So it would be 14/25. The percent in this problem would be x/100. Now to find percent with the given part/whole, you would multiply 14 with 100. Then simply divide by 25.

2(x-3)^2+10=82 solve by isolating x
Leviafan [203]
We have the following equation:
 2 (x-3) ^ 2 + 10 = 82
 We must clear x.
 We pass the constant terms to one side of the equation:
 2 (x-3) ^ 2 = 82 - 10
 2 (x-3) ^ 2 = 72
 (x-3) ^ 2 = 72/2
 (x-3) ^ 2 = 36
 Square root to both members:
 x-3 = +/- root (36)
 x-3 = +/- 6
 The solutions are:
 x1 = 6 + 3 = 9
 x2 = -6 + 3 = -3
 Answer:
 
x1 = 9
 
x2 = -3

What affect does "h" have on the parent function y = 1/x ?
pochemuha
If h moves the graph left or right, y= \frac{1}{x+h} (moves left)
y= \frac{1}{x-h} (moves right)

If a vertical stretch by a factor of |h|, then y =  \frac{h}{x}

If h moves the graph up or down, y= \frac{1}{x} +h (moves up)
y= \frac{1}{x} -h (moves down)

y= \frac{1}{-hx} and h = 1
