15 <_ -k/4 -9
I am confused how to solve this problem. Thanks
My answer is 96 <_ -k
I re did the problem and got
-d>_ 20
15 <= -k/4 + 9
6 <= -k/4
-24 >= k
or,
k <= -24
Just work it like an equation, remembering to switch directions whenever multiplying by a negative value.
To solve the inequality 15 < -k/4 - 9, we can follow these steps:
1. Start by isolating the variable "k". We can do this by moving the constant terms to the other side of the inequality:
15 + 9 < -k/4
2. Simplify the equation:
24 < -k/4
3. Multiply both sides of the inequality by -4 to eliminate the fraction:
-4 * 24 > k
4. Simplify the equation:
-96 > k
5. Finally, reverse the inequality sign since we multiplied by a negative number:
k < -96
Therefore, the solution to the inequality is k < -96. This means that any value of k which is less than -96 will satisfy the inequality.
