Example: 
We can see that there is more than one number with the variable x, therefore, we say they're ''like terms'' and because of that they can be summed. We do this with all of the other numbers with similar variables. If no numbers with similar variables are left, like 4a, you don't do anything but write them as they are. You can also see that 8 and 9 can also be summed because neither of them has a variable, therefore they're similar.
In this step, you just do the operation with the numbers and keep the same variable.


since there are not more numbers similar in variables, this operation is done.

It is not straight and does not always pass through 0,0
so A, C, and D are incorrect.
Look up nonlinear function, and it shows a curved line.
The answer is B. It can be curved.
I'm assuming that you meant 4x+1=3x?
Subtracting 4x, we get 1=-x. Multiplying by -1, we get x=-1 as the solution.
Answer:
B) ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
Step-by-step explanation:
The given expression is 
It is 4th root. because 1/4 represents the 4th root.
So, ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
Therefore, the answer is B) ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
Hi there!
The answer is B.
the cost of the game.
We need to know the cost of the game in order to find out how many weeks John has to save money. If we don't know this price, we'll never know whether John has saved enough money.
We can find out the total amount of money John can save in 1 week (so A. is not the answer). The amount of money John earns per hour doesn't matter to answer the question (so C. is wrong).
