Задание 3: Найдите значение выражения: 1. 5|х - 2|, при х = 3 2.5|r2|+ 1, при r = − 3 3. |x-5|-2|x + 1|, при х = 3 4. 10-|y+2|, при у = − 2

5 ⋅ |x - 2|, при x = 3

5 ⋅ |3 - 2| = 5 ⋅ |1| = 5 ⋅ 1 = 5

5 ⋅ |r - 2| + 1, при r = -3

5 ⋅ |-3 - 2| + 1 = 5 ⋅ |-5| + 1 = 5 ⋅ 5 + 1 = 25 + 1 = 26

|x - 5| - 2 ⋅ |x + 1|, при x = 3

|3 - 5| - 2 ⋅ |3 + 1| = |-2| - 2 ⋅ |4| = 2 - 2 ⋅ 4 = 2 - 8 = -6

10 - |y + 2|, при y = -2

10 - |-2 + 2| = 10 - |0| = 10 - 0 = 10
