40 points!! need help asap
Mekhanik [1.2K]

#1.

[4x = -12y + 16 and x + 3y = 4]

One answer


#2.

Here, y = 4x + 3

y - 4x = 3

Multiply by 2,

2y - 8x = 6

Compare with second equation,

6 ≠ 3

In short, System of Equation does not have any solution. [ Option D ]

#3.

2y=6

3x-6y=18

Divide first equation by 2: y=3

Substitute y=3 into second equation: 3x-6(3)=18

Solve for x: 3x=36 x=12

Therefore there is only one solution: x=12 y=3


#4.

y - 7x = -14

7y - 49x = -2

Rewrite the first equation as "y =" so that it can be substituted into the second equation and solve for x.

y = 7x - 14

7(7x - 14) - 49x = -2

49x - 98 - 49x = -2

-98 = -2

Since the variables cancel and the equation is not true there is no solution.

The lines are parallel and will not intersect.

A wine maker has 2 wine barrels labeled A and B. There is more wine in barrel A than in barrel B. The wine maker wants the 2 bar
Rudiy27

Answer:

Step-by-step explanation:

Gonna take this nice and slow.  First, at the end it says together both barrels have 48 pints when equal, which means added together they have 96.  This stays even as we  pout from one to the other.  So A+B = 96.  Keep that in mind.  Also I hope you're good with your systems of equations.

One step at a time.  We start with A and B

First, he doubles what is in B, which means he takes that much out of A.

A turns to A-B and B turns to 2B, hopefully you understand that.

Second A is doubled, which means that much is taken out of B.

A-B turns to 2(A-B) or 2A - 2B and 2B turns to 2B - (A - B) or 3B - A

Third and finally B is doubled again

2A - 2B turns to 2A - 2B - (3B - A) or 3A - 5B and 3B - A turns to 2(3B - A) or 6B - 2A

Now we have our system.

A + B = 96

3A - 5B = 6B - 2A or to make it a little nicer 5A = 11B

Let me know if you need help witht he system solving, but you wind up with

A = 66

B = 30

Again, let me know if you don't understand some part.
