What is 4x-2y=8 and y=2x+1 using substitution

Mathematics

8 0

Answer:

No Solution

Step-by-step explanation:

4x-2y=8

y=2x+1

Make the first equation into where it says y=.

-2y=-4x+8

y=2x-4

Substitute either equation into the other as y=.

2x+1=2x-4 or 2x-4=2x+1

Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.

2x-2x=-1-4 or 2x-2x=4+1

0=-5 0=5

Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.

What is the difference of the polynomials (5x^3+4x^2)-(6x^2-2x-9)

Alik [6]

So start by putting the negative sign into the second polynomial.
-(6x^2-2x-9)
-6x^2+2x+9
then combine like terms with the first polynomial
5x^3+4x^2-6x^2-2x+9
and you will get
5x^3-2x^2+2x+9
Hope this helps you.

USPshnik [31]

5 and 3/4 and 3 and 1/2

5 and 3/4 to 3 and 1/2 is the answer
if y ou want to convert it to whole numbers then

5 and 3/4:3 and 1/2
convert mixed numbers to improper fractions
5 and 3/4=23/4
3 and 1/2=7/2
23/4:7/2
multiply both sides by 4 to clear fractions
23:14
answer is the ratio is 23:14
