At the end of a 30-question round, you’ve gotten 23 questions correct and only 7 wrong, giving you a total score of 94 points. your friend, on the other hand, got 16 questions correct and 14 wrong for a total score of 38 points. create a system of equations to represent this situation. let x represent the amount of points received for a correct answer and y represent the amount of points for an incorrect 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.

So, the equation formed is:

23x+7y=94

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)

23x+7y=94(1)

16x+14y=38(2)

Step-by-step explanation:

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
