This is asking you to rewrite the equation so that Y is alone on one side.
First, move the 4x to the other side:
4x - 5y - 4x = 9 - 4x -->
-5y = 9 - 4x
Divide both sides by -5 to get the Y alone:
-5y/-5 = (9-4x)/(-5) -->
y = (9-4x)/(-5)
You could stop there, but some people like to make the right side look a little simpler. dividing by a negative number looks a little messy, so we rewrite the equation in a few steps. All the below are all the same thing, just written in a different way.
y = -(9-4x) / 5 -->
y = (-9+4x) / 5 -->
y = (4x - 9) / 5
The numbers can be arranged in 720 ways.
There are 6 people possible for the first position; 5 for the second; 4 for the third; etc. This gives us 6! = 720.
Answer:
the length is 9 in. and the width is 7 in.
Step-by-step explanation:
this is hard to explain but i promise that this is the correct answer.
Answer:
I believe C, or the answer you have chosen, is correct.
Step-by-step explanation:
In this question, we add like, AKA similar, terms.
There is nothing to match x^2, so we leave it alone and put it at the head of equation since it has the highest power:
x^2
There is nothing to match -x, so we also leave it alone and put it next to x^2, keeping its sign:
x^2 - x
We can add 1 and 5 to get 6, so we put 6 next to the -x to get our final equation:
x^2 - x + 6.
See how easy that was? :) Hope this helps you and you get a good grade on your test!!
