Question 1079823: Use the fact that f(x)=sqrt (x) is increasing on its domain to solve the inequalities:
8−5x≥x+7
Answer by rapture(86) (Show Source): You can put this solution on YOUR website!
8 − 5x ≥ x + 7
Solve it like you would a linear equation.
-5x - x ≥ 7 - 8
-6x ≥ - 1
We now divide both sides by -6. Since we are to divide by a negative number,
reverse the inequality sign to less than or equal to.
x ≤ -1/-6
x ≤ 1/6
