Answer: C) ![x\geq1\frac{1}{2}](https://tex.z-dn.net/?f=x%5Cgeq1%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
Let's solve your inequality step-by-step.
![4x-7\geq \frac{-12x+14}{4}](https://tex.z-dn.net/?f=4x-7%5Cgeq%20%5Cfrac%7B-12x%2B14%7D%7B4%7D)
Step 1: Simplify both sides of the inequality.
![4x-7\geq -3x +\frac{7}{2}](https://tex.z-dn.net/?f=4x-7%5Cgeq%20-3x%20%2B%5Cfrac%7B7%7D%7B2%7D)
Step 2: Add 3x to both sides.
![4x+3x-7\geq -3x+3x +\frac{7}{2}\\7x-7\geq\frac{7}{2}](https://tex.z-dn.net/?f=4x%2B3x-7%5Cgeq%20-3x%2B3x%20%2B%5Cfrac%7B7%7D%7B2%7D%5C%5C7x-7%5Cgeq%5Cfrac%7B7%7D%7B2%7D)
Step 3: Add 7 to both sides.
![7x-7+7\geq\frac{7}{2} +7\\7x\geq\frac{21}{2}](https://tex.z-dn.net/?f=7x-7%2B7%5Cgeq%5Cfrac%7B7%7D%7B2%7D%20%2B7%5C%5C7x%5Cgeq%5Cfrac%7B21%7D%7B2%7D)
Step 4: Multiply both sides by
.
![7x(\frac{1}{7}) \geq\frac{21}{2} (\frac{1}{7}) \\x\geq\frac{21}{14} \\x\geq 1\frac{1}{2}](https://tex.z-dn.net/?f=7x%28%5Cfrac%7B1%7D%7B7%7D%29%20%5Cgeq%5Cfrac%7B21%7D%7B2%7D%20%28%5Cfrac%7B1%7D%7B7%7D%29%20%5C%5Cx%5Cgeq%5Cfrac%7B21%7D%7B14%7D%20%5C%5Cx%5Cgeq%201%5Cfrac%7B1%7D%7B2%7D)
i^2 = -1
Replace i^2 with -1 and simplify:
(5(-1) - 3) * (6i*2^6) =
(-5 - 3) * (6i * 64) =
-8 * 384i =
-3072i
