Answer:
3 feets
Step-by-step explanation:
Given that :
Entire walkway uses 6 feets of brick
Width of walkway = x
Width of walkway is the same along both sides ;
SINCE, the number of sides of the walkway = 2 and each side is the same
Hence,
x + x = 6 feets
2x = 6 feets
x = 6 feets / 2
x = 3 feets
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:

45 is the answerrrrrrrrrrrrrr!!!!
