Answer:
Total number of students receiving A grade = 75
Step-by-step explanation:
Total number of students enrolled in elementary algebra this year =300
Percentage of students receiving a grade of A = 25%
To find number of students that will receive a grade of A.
Solution:
In order to find the number of students that will receive a grade of A, we will find the percentage students receiving A grade of the total number of the student.
Number of students receiving A grade = 
⇒ 
Writing 25% as fraction and multiplying.
⇒ 
⇒ 
⇒ 
∴ Total number of students receiving A grade = 75 (Answer)
Answer:
(-1, 1), (-1, 4), and (1, 4) are the vertices of a right triangle.
Step-by-step explanation:
If you were to graph these three points on a coordinate plane, you'll notice that two of the sides form a right angle together, which means this triangle will be a right triangle. If you're looking for something more specific, it would be a right scalene triangle, where all sides are different in a right triangle.
1. C) 40k + 40l (Multiply 40 by each of the factors in the parentheses and show as an addition expression.)
2. C) -4 (Divide the two numbers.)
3.D) -3
The slopes must be the same. From a table you can calculate the slope of a line segment connecting any two of the given points. Note that this slope must be consistent throughout.
From a graph, you can find the exact slope of the line, or estimate it closely.
If the slopes are the same in both graphs, the two lines are parallel to one another.
