Mathematics
1 answer:
klemol [59]4 years ago
6 0

Answer:

1.

y = -3x -3 (the graph is a straight line)

m = -3

b = -3

y = 2x + 2

m = 2

b = 2

2.

2x - y = 6

x + y = 6

_______

3x = 12

3x/3 = 12/3

x = 4

Plug x into the equation to solve for y.

2(4) - y = 6

8 - y = 6

- y = 6 - 8

- y = -2

y = 2

Your solution is ( 4, 2).

3. No the solution is ( 10 , -11/2)

- 2x - 4y = 2

3x + 4y = 8

__________

x = 10

- 2 (10) - 4y = 2

- 20 - 4y = 2

- 4y = 22

- 4y/ 4 = 22/4

y = -11/2

Bonus:

4x + 3 ( 1787 - x) = 5792

4x + 5361 - 3x = 5792

x + 5361 = 5792

x = 431 (reserved seat tickets)

Minus 1787 with 431 which is 1,356 general admission tickets.

Answer: 431 reserved seat tickets and 1,356 general admission tickets!

Hope this helps!
