Given: A = {(0, 0), (2, 1), (3, 1.5),(4,2),...) Is A a function and why? A. No, each set of ordered pairs in this list has the same range element.

B. Yes, there is more than one ordered pair in this list.

C. Yes, no two ordered pairs in this list has a repeat of the domain element.

D. No, there is a limited number of ordered pairs in this list.

C. Yes, no two ordered pairs in this list has a repeat of the domain element.

Step-by-step explanation:

An equation that produces a set of ordered pairs defines a function, but it needs to be a proper function!

A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. Which means that answer C is correct.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
