75% of students = 18
Divide by 3 to find 25% of students.
25% of students = 6
Add the two together or multiply the 25% of students by 4 to get the total number of students.
25% + 75% = 6 + 18 = 24 students
or
25%*4 = 6*4 = 24 students
It is the equation in the simplest form
Answer: The answer is -80
Step-by-step explanation:
2(2^2)+(3)(2)(−4)−4(−4)^2
2(2^2)+(3)(2)(−4)−4(−4)^2
=−80
Answer:
See explanation.
Step-by-step explanation:
Graph the quadrilateral. By inspection, you can tell where the midpoint is. (see attachment 1)
Now, I'll draw a line through it. (see attachment 2)
To reflect across a line, think about the points traveling across the line the same number of spaces the point is from the line. For example, point A is three away from the line. So, A' will be 3 away from the other side. The coordinates will be at (-3,2). (see attachment 3).
Do the same for the other points, and you'll have your image.
Given function:

The minimum value of the function can be found by setting the first derivative of the function to zero.


Solving for x:


Substituting the value of x into the original function:

Hence, the minimum value in the given range is (-1, -0.368)
