what value of x is in the solution set of the inequality -5x - 15 > 10 + 20x?\n-2\n-1\n0\n1
Answer
Explanation:
Step1: Move like - terms together
Add (5x) to both sides and subtract (10) from both sides of the inequality (-5x - 15>10 + 20x). We get (-5x-20x>10 + 15).
Step2: Simplify both sides
Combining like - terms, (-25x>25).
Step3: Solve for (x)
Divide both sides of the inequality by (-25). When dividing an inequality by a negative number, the direction of the inequality sign changes. So (x<-1).
Answer:
A. (-2)
