Answer:
- 4 < x ≤ 7
Step-by-step explanation:
Given
- 10 ≤ - 5x + 25 < 45 ( subtract 25 from all 3 intervals )
- 35 ≤ - 5x < 20
Divide all 3 intervals by - 5, reversing the inequality signs as a consequence.
7 ≥ x > - 4
Hence - 4 < x ≤ 7
Any unknown number in an equation you represent with a variable
To fully answer this question you would have to list the plynomials or provide a picture of the question, but the answer you're looking for will have the highest exponent be 2 an example of a plynomial like this would be 94x^2 - 54y + 17x - 49
It would be D , please tell me if I’m correct
