حل السؤال 18، 4MA1/2FR يناير 2021: إيجاد المناطق من المتباينات المتعددة

1. 1The horizontal line passing through y = 1 forms the lower boundary of R, so y must be greater than or equal to 1: y ≥ 1
2. 2The vertical line passing through x = 3 forms the right boundary of R, so x must be less than or equal to 3: x ≤ 3
3. 3The line y = 3x − 2 forms the upper boundary of R, and since R is below this line, y must be less than or equal to 3x − 2: y ≤ 3x − 2

Answery ≥ 1, x ≤ 3, y ≤ 3x − 2
