First one: y - y1 = m(x - x1).
Second one: Choose whichever point to use for (x1,y1); see previous equation in #1.
Third one: (0,7)(-6,-6) (2,-2) ????????? Does not form a line.
Most common ways are:
Crossing out similar terms: Ex. 5x^2/x^2...the x^2's can be crossed out leaving us with 5.
Collecting like terms: Ex. 4x + 9x + 5 --> 13x + 5.
Distributing and then collecting like terms: Ex. 4(x+1) + x --> 4x + 4 + x --> 5x + 4.
Exponents: Ex. 5x^-2 --> 5/x^2.
Think of .352 as 352. How would you go from .352 to 352? 352/1000.
Now, you just need to keep on dividing by 2's or choose a larger number until you reduce it all the way.
Divide both sides by 8:
$$x \le -4.$$
All you have to do is cross multiply:
If you need n/25 = 26...do the same process except you have 26 instead of 25.
What is 60% of 800? Is it less than 553? Then, no, it is not unusual.
This doesn't make sense.
