Answer:
-7 and -10 are solutions, 5 and 0 aren't
Explanation:
For the inequality, -4 + 5y will have to be less than or equal to -39. So, y would have to be a negative number. That would remove 5 as a possible solution.
Next, we can calculate the solution for others. For 0, we can multiply it by 5 and get 0. Then, add it to -4 which would get us -4. This is greater than -39 so 0 isn't a solution.
If we solve for -7, we'll get: -4 + 5(-7) -> -4 - 35 -> -39. This is equal to -39 so it is a solution. If we solve for -10, we get: -4 + 5(-10) -> -4 - 50 -> -54. This is less than -39 so it is a solution.
