Does this set of ordered pairs represent a function? Why or why not ?

Answer:
C. Yes, because every x-value corresponds to exactly one y-value
Step-by-step explanation:
We are asked to find whether the given ordered pairs represent a function or not.
We know that a relation is a function, when each input of x value gives exactly one output of y-value.
In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.
We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.

Answer:
The area of the wall on the blueprint is 0.1764 ft²
Step-by-step explanation:
The scale is the relationship that exists between the magnitudes of a drawing and the actual dimensions.
The scale factor is the ratio of the dimensions in two similar figures. The term "similar figures" refers to figures that have the same shape but different sizes.
The ratio between areas is equal to the squared scale factor. This is, the scale factor for areas is the squared scale factor,
To solve scale problems in this case, then the following proportion must be proposed:
Being:
- representation area=?
- actual area=36 ft²
- scale factor=0.07
Replacing:
Solving:
representation area= 0.07²*36 ft²
representation area=0.1764 ft²
