-1/4k is greater than 18
i have no idea!!!!!
btw, i don't know if i should switch the sign (greater than or less than) or if it should be negative! thank you
I am not certain what the question is. Assuming it is to find k
-1/4k>18
multiply both sides by 4k
-1>72k
divide both sides by 72
-1/72>k or
k<-1/72 so k is negative, from -1/72 to - infinity.
i don't know what you mean by infinity?? thanks for the other help (:
-infinity is the most negative number you can comprehend, less one more.
To determine whether -1/4k is greater than 18, we can proceed as follows:
Step 1: Simplify the expression -1/4k.
The expression -1/4k indicates that we have the product of -1/4 and k. We cannot determine the value of k solely based on this expression.
Step 2: Set up the inequality.
We want to compare -1/4k with 18, so we set up an inequality as follows:
-1/4k > 18
Step 3: Solve the inequality.
To solve the inequality, we isolate the variable k.
Multiply both sides of the inequality by 4 to eliminate the denominator:
4 * (-1/4k) > 4 * 18
-1k > 72
Multiply both sides by -1 and reverse the inequality sign:
k < -72
Step 4: Interpret the result.
The inequality k < -72 indicates that for any value of k less than -72, the expression -1/4k will be greater than 18.
Therefore, -1/4k is greater than 18 if k is any value less than -72.
