Answer:
This is a many-to-one function as the value of y = -1 corresponds to two values of x:

Step-by-step explanation:
<u>Function</u>
A special relationship where each input (x-value) has a single output (y-value).
A function is <u>one-to-one</u> if each value in the range (y-values) corresponds to exactly one value in the domain (x-values).
A function is <u>many-to-one</u> if some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).
This is a many-to-one function as the value of y = -1 corresponds to two values of x:

This is not a function as the value of x = -5 corresponds to two values of y:

This is not a function as the value of x = -2 corresponds to two values of y:

This is not a function as the value of x = -4 corresponds to two values of y:

Answer: my but
Step-by-step explanation:
1+1
Add, -11.5x and move it over to 8.5x
Then, subtract them together and you get 20x + 51.86 = 51.76
And you move (subtract) 51. 86 over to 51.76, subtract that and you get 20x = -0.1
Divide, and your answer is -200
