x + 3y = 7 x - 3y = 1 Solve the system of equations. A) x = 4, y = 1 B) x = 1, y = 4 C) x = - 2 3 , y = 3 D) x = 3, y = - 2 3

Answers

x+3y=7
x-3y=1
add them together

x+3y=7
x-3y=1 +
2x+0y=8

x+3y=7
4+3y=7
subtract 4
3y=3
divid 3
y=1

x=4
y=1

answer is A

X + 3y = 7
x - 3y = 1

x + 3y = 7
- 3y -3y

x = 7 - 3y

x - 3y = 1
7 - 3y - 3y = 1
7 -6y = 1
-7 -7

-6y = -6
y = 1

Now solve for x

X + 3y = 7
x + 3 = 7
x = 4

Now we have our values:-
x = 4 and y = 1

Answer: A) x = 4, y = 1

Answer: W= -4/3=-1.33333

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

w*(-3)-(-3+7)=0

Pull out like factors : -3w - 4 = -1 • (3w + 4)

Solve : -3w-4 = 0

Add 4 to both sides of the equation :

-3w = 4

Multiply both sides of the equation by (-1) : 3w = -4

w = -4/3 = -1.333

Calculate the difference (home-away) in winning percentage. A) Need more information B) Positive C) Negative D) Zero

Answers

To calculate the difference in winning percentage (home - away), we do need more information. We would need the winning percentages for both home games and away games to determine whether the difference is positive, negative, or zero.

So, the correct answer is A) Need more information.
