Answer:
Neither
Step-by-step explanation:
equation 1 is a negative slope, equation 2 is a positive slope, but with a different slope.
I would say that the "n"th term of the sequence is 41, as the pattern increases by 10 every term.
The order of operations is a system for simplifying expressions that ensures that there is only one right answer.
Answer:
Given lines are PERPENDICULAR to each other.
Step-by-step explanation:
We have the equations,
and 
The slope-intercept form of a straight line is 'y=mx+b', where m is the slope and b is the y-intercept.
So, accordingly we get that,
The given equations have slopes
and
.
As we see that, 
Thus, the product of the slopes of the given lines is -1.
Hence, the given lines are PERPENDICULAR to each other.
Answer:
$75
Step-by-step explanation:
If their bill is $55 and they leave a $20 tip that's pretty much adding 20 +55
so $20 + $55 dollars is $75.
I hope that helped.
