Solve for z.z−7≥11 or z−16≤−7Write your answer as a compound inequality with integers.Choices:(A)z≥18 or z≤9(B)z > 18 or z < 9(C)z > 18 or z≤9(D)z≥18 or z < 9
Q. Solve for z.z−7≥11 or z−16≤−7Write your answer as a compound inequality with integers.Choices:(A)z≥18 or z≤9(B)z>18 or z<9(C)z>18 or z≤9(D)z≥18 or z<9
Addition to Isolate z: To solve the inequality z−7≥11, we need to isolate z by adding 7 to both sides of the inequality.Calculation: z−7+7≥11+7z≥18
Combine Compound Inequality: To solve the inequality z−16≤−7, we need to isolate z by adding 16 to both sides of the inequality.Calculation: z−16+16≤−7+16z≤9
Combine Compound Inequality: To solve the inequality z−16≤−7, we need to isolate z by adding 16 to both sides of the inequality.Calculation: z−16+16≤−7+16z≤9Now we combine both parts of the compound inequality using "or" because the original problem states "z−7≥11 or z−16≤−7".The combined compound inequality is z≥18 or z≤9.
