Answer:
the graph is attached
Step-by-step explanation:
This sort of equation makes it easy to find the x- and y-intercepts. Setting x to zero gives ...
y = -11 . . . . . the y-intercept
Setting y to zero gives ...
x = -11 . . . . . the x-intercept
You can plot these two points, then draw a line through them to complete the graph.
Every point on this line is a solution to the equation.
To check if two vectors are orthogonal(perpendicular), simply check their dot product, if their dot product is 0, then they're perpendicular, let's check.
to check if two vectors are parallel, simply check their slope by doing a b/a check, if the slopes are the same, then they're indeed parallel to each other, let's check.
well, there you have it, the slopes are the same.

Answer:
p = 30
angles 30°, 45°; exterior: 75°
Step-by-step explanation:
The exterior angle is equal to the sum of the remote interior angle:
3p -15 = p + (p +15)
p = 30 . . . . . . . . . . . . . add 15-2p
The interior angles are 30°, 45°; the exterior angle is 75°.
