Answer:
The top lines in the middle of the envelope are 45 degree angles, and the rest are 180 degrees, and 90 degrees.
Step-by-step explanation:
Answer:
Check the attached graph
Step-by-step explanation:
Given equation is
.
Now we need to graph the given equation
..
Clearly it is not linear as equation is not of the form
. So we need to find some points on given equation
. by plugging some random values of x like -5,-3,1,... etc.
for x=-5, we get:

.
Hence first point is at (-5,-2). Similarly we can find more points and graph those points.
x can't be 0 as division by 0 is not defined so it will have vertical asymptote at x=0.
Since degree of numerator is less than degree of denominator so y=0 will be horizontal asymptote.
Now join those points by a curved line to get final graph.

Answer:
x = 17
y = 8
QPR = 35º
QRP = 60º
Step-by-step explanation:
2x + 1 = x + 18
Subtract x from both sides
x + 1 = 18
Subtract 1 from both sides
x = 17
QPR = 2x + 1
QPR = 2(17) + 1
QPR = 35º
-------------------------------
8y - 4 = 4y + 28
Subtract 4y from both sides
4y - 4 = 28
Add 4 to both sides
4y = 32
Divide both sides by 4
y = 8
QPR = 8y - 4
QRP = 8(8) - 4
QRP = 60º
