Elimination method 2x -3y=7 3x-2y=13
strojnjashka [21]

Answer:

x = 5 and y = 1 or (5, 1)

Step-by-step explanation:

2x -3y=7

3x-2y=13

Multiply (1st) equation by 3 and (2nd) equation by 2

6x -9y=21

6x-4y=26

----------------subtract

-5y = - 5

y = 1

Substitute y = 1 into 2x -3y=7

2x -3(1)=7

2x - 3 = 7

2x = 10

x = 5

Answer

x = 5 and y = 1 or (5, 1)

How many factors does the following term have? <br><br> 2xy
egoroff_w [7]

<u>Answer:</u>

  • 4 factors.

<u>Explanation:</u>

<em>Factors are numbers that if they are divided, then they would be divisible. We can see that the term is multiplied with 3 terms. Hence, they are definitely factors of that term. However, there is one more factor that is divisible by 2xy. The number 1 is divisible by 2xy. Hence, the factors of this term is 2, x, y, and 1.</em>

Hoped this helped.

Does anyone know how to do these? I don't understand it at all and need help! It is solving systems of equations by graphing
alexira [117]

Step-by-step explanation: graph both equations where they intersect is the answer write it like this (x,y) the x and the y should be replaced with the numbers you'll get when they intersect. So if they intersected the point where they did if the y is 1 and x is 2 then the answer is (2,1). If they don't intersect at all and are parallel then it is no solution. If your only graphing one line which you aren't in this case but if you were it would be infinitely many.
