The correct answer is (b) disadvantages. This is because air pollution would be considered a negative aspect of city life, a.k.a. a disadvantage.

### Subject:Algebra

Question:

Determine whether each of the following numbers are solutions to the given equation. (a) (x=6) in x^2 - 36 = 0 (b) (z= -2) in 3(z + 1) = 4z - 5

(a) We first plug the proposed solution into the equation: (6)^2 - 36 = 0 36 - 36 = 0 0 = 0 THIS WORKS So, what we are asking here is does the right side equal the left side after we plug in the proposed solution - because the left and right sides match, we can say that x = 6 satisfies this equation. (b) In this case, we do essentially the same thing that we did in the previous example - plug in the number given, and see if it satisfies the equation. 3 ( (-2) + 1) = 4(-2) - 5 3 (-1) = (-8) - 5 -3 = -13 THIS DOES NOT WORK Because the left side (-3) is not the same as the right side (-13), this equation is not satisfied and therefore, z = -2 is NOT a solution.
