Question

solve the inequality and exp solution set on the real num 9x + 9 > 9(x + 7) (-∞, ∞) (0, ∞) (-∞, 0)

Explanation:

Step1: Expand the right-hand side

$9x + 9 > 9x + 63$

Step2: Subtract $9x$ from both sides

$9 > 63$

Answer:

There is no real number solution (the inequality is never true, so no option provided is correct; the statement $9>63$ is false, meaning no $x$ satisfies the original inequality).
