Question

solve using the multiplication principle. give the answer in set-builder notation.
-4/5 15 years ago

Answer 1

We have:

\[-\frac{4}{5} \leq -6x \]

We can divide by -6 on either side, but remember that dividing by a negative flips the inequality; so we have:

\[-\frac{4}{-5\cdot 6} \geq x\]
\[-\frac{4}{30} \geq x\]
Can you simplify that fraction and write it the inequality set-builder notation?

Answer 2

So shadowfend, would the answer be x > greater than or equal to -2/15

Answer 3

Not quite, I made a sign error up there. The negatives cancel. And you said greather than or equal to whereas that should be less than or equal to. So:

\[x \leq \frac{2}{15}\]

Do you know how to put that in set-builder notation?
