Solve:
3y - 9x = 24
Let's solve for x.
3y − 9x = 24
Step 1: Add -3y to both sides.
−9x + 3y + −3y = 24 + −3y
−9x = −3y + 24
Step 2: Divide both sides by -9.
−9x / - 9 = -3y + 24 / -9
x = 1 / 3y + -8 / 3
Answer: =======> x = 1 / 3y + -8 / 3
Graph: 3y - 9x = 24 ==========> y = 3x + 8
Interception points of: 3x + 8
x intercepts: ======> ( -8/3, 0 )
y intercepts: =======> ( 0, 8 )
Answer: =======> x = 1 / 3y + -8 / 3
Hope that helps!!!! : )
I think the answer would be
20, the LCM
(least common multiple) :)
A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator
opposites are also called additive inverse and have the sum of zero.
Answer:
Part A: 20 students
Part B: 4 hours
Step-by-step explanation:
Part A:
To find the number of students surveyed, we count the number of x there are in the graph.
students = 1 + 2 + 3 + 5 + 1 + 1 + 3 + 2 + 2 = 20
Part B:
To find the mean, we need to find the total number of hours volunteered first.
hours = 1x0 + 2x1 + 3x3 + 5x3 + 1x4 + 1x5 + 3x6 + 2x7 + 2x8 = 80
Now, we can find the mean. We divide the total number of hours volunteered by the number of students.
Mean = 80 ÷ 20 = 4
