Answer:
none are perpendicular
Step-by-step explanation:
thye are parallel
D: {1,2,3,4}
R: {1,2,3,4}
Function? Yes, the relation is a function.
Answer:

Step-by-step explanation:
1. Value of x
The diagonals of a rectangle are equal, so
PR = QS

2. Length of each diagonal
PR = 11x - 20 = 11×18 - 20 = 198 - 20 = 178
QS = x + 160 = 18 + 160 = 178
The length of each diagonal is 178.
Answer:
Quadrant 3
Step-by-step explanation:
Here we have to graph the function y = x/(x^2 + 2x + 1)
The denominator can be factored.
x^2 + 2x + 1 = (x + 1)(x + 1)
y = x/(x + 1)(x + 1)
Now we have to graph this function and see in which quadrant the function's both branches passes through.
Herewith I have attached the graph.
Here we can see both branches pass through Quadrant 3.
I hope this will helpful.
Thank you.
the formula for slope is

so just replace y and x for the proper values
