Which of the following relations is a function?
a. (11, 5), (3, -8), (7, 0), (11, -6)
b. (0, 11), (-8, 3), (0, 7), (-8, -6)
c. (5, 11), (-8, 3), (0, 7), (0, -6)
d. (5, 11), (-8, 3), (0, 7), (-6, 11)

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
