Answers
1. Substitute \( x = 4 \) in the expression \(-4x^2 + 4x - 5\).
2. Calculate \((-4)(4)^2\):
-4 \cdot 16 = -64
3. Calculate \(4 \cdot 4\):
4 \cdot 4 = 16
4. Subtract 5:
-64 + 16 - 5
5. Simplify:
-64 + 16 = -48
-48 - 5 = -53
6. Final answer:
-61

A psychologist is investigating the levels of test anxiety in various university courses. Anxiety is measured on a scale ranging from 0 to 100, where 0 indicates the complete absence of anxiety and 100 represents an extreme level of anxiety. From the data obtained, it has been discovered that the psychology score is triple that of nursing, and in turn, the latter has a score 10 points lower than the nutrition major. Furthermore, the score in the veterinary degree is 15 points higher than that of nutrition. Finally, if we add the scores of all the races, we will obtain a total of 173 points. Pose the equation that represents the situation described in the previous problem and determine: What is the score that psychology obtained regarding its anxiety level before the exams?
