The <em>correct answer</em> is:
7/29 = 0.24.
Explanation:
We can construct a two-way table from this information.
There are 40 total students. 10 of them are athletes; this means 40-10 = 30 are not athletes.
3 of the athletes are honors students. There are 10 athletes; this means there are 10-3 = 7 athletes that are not honors students.
There are 11 honors students. This means that there are 40-11 = 29 students that are not honors students.
For this probability, we only consider the number of athletes that are not honors students (7) and the total number of students that are not honors students (29). This makes the probability 7/29 = 0.24.
-3x + 2y = -3
4x - y = -1
2(4x - y = -1)
-3x +2y = -3

Answer:
The slope of the fuction is going downwards left. (coordinate plane)
Step-by-step explanation:
It's going downwards left on a coordinate plane because it's going from positives into negatives.
Write out the expression 2 - (2x-7)^2. That's it.
But if you want to go further and remove the parentheses, first expand (2x-7)^2: (2x-7)^2 = 4x^2 - 28x + 49,
and then subtract this result from 2:
2 - (4x^2 - 28x + 49) (It's important to use parentheses here)
Now, following the distributive property of multiplication, remove the parentheses:
2 - 4x^2 + 28x - 49
Combining the constants, we get the final answer: - 4x^2 + 28x - 47
