Answer:
1
Step-by-step explanation:
There can be 0, 1 or infinitely many solutions. 0 if they are parallel and are different lines, 1 if the slopes are different, and infinitely many if they are the same line.
2x - 4y = 8
x + y = 7
Change to y = mx + b
y = (1/2)x - 2
y = -x + 7
The slopes are different so there is 1 solution.

Answer:7.25 feet
Step-by-step explanation:
6.25+6.5=12.75
20-12.75=7.25
Answer:
The answer will be listed below.
Step-by-step explanation:
First of all, you want x to by itself, so distribute the three to both x and negative 4 so you'll get 3x-12=2x+6.
Now, subtract 2x from both sides and add 12 to both sides and you'll get an answer of x=19. From that, you are able conclude that this equation has one solution.
Cross-multiplying and rearranging, we get:
or written without using latex:
k^2 = h^2 - 3mq
