Answer:
The expression -2a + 1 remains as is for cases 2 and 3, while for case 1, the simplified expression is -3.
Step-by-step explanation:
To evaluate the expression -2a + 1 for the given conditions, let's consider each case:
1) When a ≥ 2:
In this case, the expression -2a + 1 can be simplified by substituting the value of a:
-2(2) + 1 = -4 + 1 = -3
2) When a < 1:
Substituting the value of a into the expression, we get:
-2(a) + 1 = -2(a) + 1 = -2a + 1
Since a is less than 1, we cannot simplify the expression further without knowing the specific value of a.
3) When -1 ≤ a < 2:
Similar to the previous case, we can substitute the value of a into the expression:
-2(a) + 1 = -2(a) + 1 = -2a + 1
Again, without knowing the specific value of a within the given range, we cannot simplify the expression further.
Therefore, the expression -2a + 1 remains as is for cases 2 and 3, while for case 1, the simplified expression is -3.
I hope this clarifies the evaluation of the expression for the given conditions. Let me know if you have any further questions.
