Is (1,-1) a solution of y=3x+2

Mathematics
1 answer:
viva [34]4 years ago

In order to check a solution, just plug in the coordinates.  The 1 is x, and the -1 is the y.  Just plug the numbers in and see if it works out:

y = 3x + 2
(-1) = 3(1) + 2
-1 = 5

-1 is NOT equal to 5, so (1, -1) is NOT a solution of y = 3x + 2.

Answer:

5x^4 -7x^3-5x^2+5x+1

Step-by-step explanation:

Hey!

You would just add all the numbers up, and by making sure that you combine all like terms. In this case it is just 1-0 = 1 and so the solution would be the same as your question but with a 1 and you would get rid of the -0.

Hope this helps!
