Question

If -3y > 21 which inequality gives the range of values of Y A by < - 7 B y > - 7 C y > 7 D y < 7

Answer 1

To solve the inequality \(-3y > 21\), we can divide both sides by -3. Remember that when dividing or multiplying both sides of an inequality by a negative number, the direction of the inequality sign changes.

So, we divide:

\[
-3y > 21
\]

Dividing both sides by -3, we get:

\[
y < \frac{21}{-3}
\]

\[
y < -7
\]

Thus, the correct answer is:

**D. y < -7**.
