Answer:
Step-by-step explanation:
8x-1+6x+13=180 degree(being co interior angle)
14x=180-12
x=168/14
x=12
Answer:
False
Step-by-step explanation:
It is infinitely many solutions
If the equations are not equal, that's when there are no solutions
Infinitely many solutions means that the 2 lines are scalar multiples of each other. They are basically over lapping lines, one of the line just has larger coefficients
EX: x + y = 2
2x + 2x = 4
*These two lines are just scalar multiples of each other. The second equation is just the first equation multiplied by 2. They are the same line.
So any point (x, y) that is on one line is also on the other (these are solutions to the system). There are an infinite amount of points on the line that satisfy the system, so there are infinitely many solutions
Solving this using elimination....
-2x - 2y = -4 (multiply the first equation by -2)
2x + 2y = 4
Now add them....
0 = 0

Answer:
the slope is 3 because everytime the line goes up 3 it moves to the right 1
Answer:
He paid 80 at the start, so his starting must have been 80
Step-by-step explanation:
80+40=120...
so either 0, or 80 because he owed nothing, or he owed the 80, then the 40 for medication
I hope this helps!
