Hello there!
Simply find a common term that they all have!
So they can all be divided by 6, right? So let's take a 6 out.
6 (x^2-8x-20)
Now factor the terms in the parenthesis!
6 (x-10) (x-2)
^ This is NOT your answer!!
Tip: When looking at (x^2-8x-20), look at the middle term. (-8x). Since it's negative, either (x-10) or (x-2) can be negative.
Which one is negative? Well, is the 8 positive or negative? Since the 8 is negative, the parenthesis bigger number (x-10) will be negative!
So it'll be:
6 (x-10) (x+2)
ALWAYS double check your answer by foiling! :)
Hope this helped!

Answer:
The dollar bills d are the independent variable while the number of quarters q are the dependent variable
Step-by-step explanation:
Here, we want to state the variable that is dependent and the one that is independent
from the question, she has to put in dollars to get the quarters
so the number of quarters she gets is dependent on the number of dollars put into the machine
Thus, we can conclude that;
The dollar bills are the independent variable while the number of quarters q are the dependent variable
Answer:
f(x) = 
x
Step-by-step explanation:
The first thing we need to find is the slope of the line able to pass through the given two points. Right now we have <em>y = mx + b</em> (linear function equation) and we need to find <em>m</em>.
- Using the slope formula or
and plugging in the given points' x and y values:
= 
=
- The slope of the line is that for every 5 units the line goes upwards, it goes 2 units to the right.
Our equation is now <em>y = x + b</em>. If you were in need of it, <em>b </em>gives the line's y-intercept, the place where it hits the y-axis. In this case you do not need <em>b</em> because the only specified conditions in the problem are the units the line hits.
Our final equation is:
f(x) = x
