Given Situation: What is the percent increase from the 20 students to the 30 students.
Solution:
=> Let’s find how many percent did it increase.
Let’s have 20 as the first total number of the students in the first counts.
=> Then it became 30 students, let’s find out how many students added.
=> 30 – 20 = 10, there are 10 students added
10 is 50% of 20, thus, 50% added to the number of students. And that makes it 30 as the total count.
X = 0 or x = -1
You can solve this by using the second equation, which is already solved for y and subbing that in for y in the first equation.
14x + (3x^2 - 11x - 4) = -4
14x + 3x^2 - 11x = 0
3x^2 + 3x = 0
Then you can solve by pulling out the greatest common factor
3x(x + 1) = 0
Then set each part equal to 0
3x = 0
x = 0
x + 1 = 0
x = -1
