The first answer and the last one
Plug in each number into their designated spots.
Example with (0,5)
0 goes into x and 5 goes into the y variable and this is the equation now:
2*0 +4*5=20
0 times 2 = 0 and 4*5=20
So that is one of the correct answers.
Repeat the process and you find that the last option is also correct.
Well let's say x = -1000
That's what I would do
Alright, let's do this! If $25 is one fifth of how much the game system cost then, multiply 25 times 5. And you should get your answer.
I hope this helps.
The greatest common factor of 645 and 570 would be <u>35</u>.
The error is that both sides of the equation have a variable. So if you were to combine your like terms, then you'd leave one side without a number and if your teacher is saying there is a left over number then it will be 0
