Answer:

Hence, the system of equations that is used to represent the situation is:

23x+7y=94-----(1)

16x+14y=38------(2)

Step-by-step explanation:

Let x represent the amount of points received for a correct answer and y represent the amount of points for an incorrect answer.

  • You’ve gotten 23 questions correct and only 7 wrong,giving you a total score of 94 points.

So, the equation formed is:

23x+7y=94

  • Your friend, on the other hand, got 16 questions correct and 14 wrong for a total score of 38 points.

So, the equation formed is:

16x+14y=38

Hence, the system of equations that is used to represent the situation is:

23x+7y=94-----(1)

16x+14y=38------(2)

Beyonce is solving a system of equations: 2x - 3y = - 2 and 4x + y = 24 She multiplies the second equation by 3 and then adds th
zmey [24]

Answer:

Yes, Beyonce will get the same solution.

Step-by-step explanation:

The given system is

2x - 3y = - 2

and

4x + y = 24

If she multiplies the first equation by -2 , she gets,

-4x+6y=4

4x + y = 24

Adding the two equations gives

7y=28

This means y=4

When we put y=4 into the bottom equation we get:

4x+4=24

4x=20

x=5

Therefore Beyonce will still get x=5, and y=4 as solution.
