Question

select the values that make the inequality $-k > 8$ true. then write an equivalent inequality, in terms of $k$. (numbers written in order from least to greatest going across.) answer attempt 1 out of 2 -13 -9 -8.1 -8 -7.9 -7 -3 0 3 7 7.9 8 8.1 9 13 equivalent inequality: $k$ submit answer

Explanation:

Step1: Solve the inequality \(-k > 8\)

To solve for \(k\), we multiply both sides of the inequality by \(-1\). Remember that when we multiply or divide an inequality by a negative number, the direction of the inequality sign flips. So, multiplying both sides of \(-k > 8\) by \(-1\) gives us \(k < -8\).

Step2: Identify values less than \(-8\)

Now we check each value:

• \(-13\): \(-13 < -8\), so this is valid.
• \(-9\): \(-9 < -8\), so this is valid.
• \(-8.1\): \(-8.1 < -8\), so this is valid.
• \(-8\): \(-8\) is not less than \(-8\) (it's equal), so invalid.
• \(-7.9\): \(-7.9 > -8\), invalid.
• \(-7\): \(-7 > -8\), invalid.
• \(-3\): \(-3 > -8\), invalid.
• \(0\): \(0 > -8\), invalid.
• \(3\): \(3 > -8\), invalid.
• \(7\): \(7 > -8\), invalid.
• \(7.9\): \(7.9 > -8\), invalid.
• \(8\): \(8 > -8\), invalid.
• \(8.1\): \(8.1 > -8\), invalid.
• \(9\): \(9 > -8\), invalid.
• \(13\): \(13 > -8\), invalid.

Answer:

Values that make \(-k > 8\) true: \(-13\), \(-9\), \(-8.1\)

Equivalent Inequality: \(k < -8\)
