Answer: C) perpendicular</h3>
Explanation:
Each equation given to you is in y = mx+b form (aka slope intercept form).
The slope m is what we'll focus on.
The first equation has slope of 1, while the second equation has slope -1.
The two slopes multiply to -1. This is a property of any pair of perpendicular lines, as long as neither line is vertical nor horizontal.
Or you could note that -1 is the negative reciprocal of 1, or vice versa.
So there are a few options to see why the lines are perpendicular.
In this situation you would add 9 to the other side of the inequality 2/5x < 9/10+9
2/5x< 9.9

No is not the same
2/1 = 2
1/4 = .25
The answer:
58 degrees
Explaining:
You have a right triangle with and opposite side length of 67 and an adjacent side length of 41. You will use the inverse of tan in the equation because you are finding the angle measurement .
X=tan^-1(67/41)
X=58 degrees
