The set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.
<h3>When does a relation represents a function?</h3>
A set, or a relation, represents a function when <u>each value of x is mapped to only one value of y</u>.
In this problem, we have that option A represents a function, as:
- In option B, x = 2 and x = -2 are mapped to two values.
- In option C, x = 4 is mapped to four values.
- In option D, both x = 1 and x = 2 are mapped to two values.
Hence the set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.

Answer:
Step-by-step explanation:
Let
x ----> the length of Zach's car
y ----> the length of Ginny's car
we know that
The sum of the lengths of both cars is 30 inches
so
----> equation A
Ginny's car is 2 more than 3 times the length of Zach's car
so
----> equation B
substitute equation B in equation A
Its A.
because if the base is 13 and 13 and the sides are 10 cm multiply and get A.
X= -3
2/3x-10=12
Step 1: Add 10 to both sides.
2/3x=-2
Step 2: Multiply both sides by 3/2.
x= -3
