Answer:
B
Step-by-step explanation:
X = 29 by the alternate interior angles
y = 49 by the triangle sum theorem
z = 102 because the opposite sides of a parallelogram are congruent
What that person said ^^^^
This is true. IDK if there is a question behind it.
Answer:
D) Quadratic
Step-by-step explanation:
A function is graphed on a coordinate grid.
- As the domain values approach infinity, the range values approach infinity.
Domain: If
then
Range:
- As the domain values negative infinity, the range values approach infinity.
Domain: If
then
Range:
We need to choose correct option which follows given domain and range.
Only quadratic function will follow the rule because it has even degree polynomial.
Quadratic function:
Degree = 2 and leading coefficient is positive.
Domain: 
Range: 
Hence, D is correct option.
3cot²x - 5cotx = -2
Lets pretend cotx = t
3t² - 5t = -2
3t² - 5t + 2 = 0
factor polynomial
(3t-2)(t-1) = 0
3t-2 = 0
t-1 = 0
then "t" which is also cotx is equal to 1 or 2/3
