Answer:
5\beta ???
Step-by-step explanation:
please recheck the question ..
It would be choice "D". When you change all these equations into slope-intercept form (Y=mx+b or Y equals the slope times "X" plus the y-intercept), choice "D" is the only one with the same slope which is the the value of "m" in slope-intercept form. In this case, when both equations in choice "D" is changed to slope-intercept form, both equations' slopes become -2. When slopes of two equations are the same, the lines are parallel to each other when graphed.
Answer:
p is perpendicular to n. Proved.
Step-by-step explanation:
See the diagram attached.
Let us assume that mm' and nn' are two straight lines parallel to each other and pp' is a transversal.
It is given that pp' is perpendicular to mm' i.e. ∠po'm = 90°
Now, since mm'║nn' and pp' is a transversal, so, ∠pon = ∠po'm = 90° {Those are corresponding angles}
So, pp' is also perpendicular to nn'. {Proved}
