First, you have to make sure that two fractions have the same denominator. he best way to do that is:
For Example: 4 7 8 7
---- + ----- = ----- + -----
10 20 20 20
Then, just add or subtract the numerators and you got your answer.
Boom.
A system of equations with infinitely many solutions is a system where the two equations are identical. The lines coincide. Anything that is equal to
![3y=2x-9](https://tex.z-dn.net/?f=3y%3D2x-9)
will work. You could try multiply the entire equation by some number, or moving terms around, or adding terms to both sides, or any combination of operations that you apply to the entire equation.
You could multiply the whole thing by 4.5 to get
![13.5y=9x-40.5](https://tex.z-dn.net/?f=13.5y%3D9x-40.5)
. If you want, you could mix things up and write it in slope-intercept form:
![y= \frac{2}{3}x-3](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B2%7D%7B3%7Dx-3)
. The point is, anything that is equivalent to the original equation will give infinitely many solutions x and y. You can test this by plugging in values x and y and seeing the answers!
The attached graph shows that four different equations are really the same.
This is how you do it: you put mile 96 over 3 and if u wanna know how many it will run in 1 hour. You cross multiply so you multiply 96 times1 and you get 96 but now you have to divide it by 3. If you do that you'll get the answer which is 32. There are other ways to do it but I just think it's way easier this way
The set operations are Union, Intersection and Complementation.
Subtraction, Multiplication and Division are not set operations.
Answer:
![5^2x^3y](https://tex.z-dn.net/?f=%205%5E2x%5E3y%20)
Step-by-step explanation:
There are 2 factors of 5, so you have 5^2
There are 3 factors of x, so you have x^3
There is a single y, so you have y
Answer: ![5^2x^3y](https://tex.z-dn.net/?f=%205%5E2x%5E3y%20)
