Answer:
y - 8 = -2(x + 3)
General Formulas and Concepts:
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate
y₁ - y coordinate
m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = -2
Point (-3, 8)
<u>Step 2: Write equation</u>
y - 8 = -2(x + 3)

Answer:
85.714285714
Step-by-step explanation:
Section A
15 students has a mean score of 80
The Total score of the 15 students =
15 × 80
= 1200
Section B
20 students had a mean score of 90
Total score of the 20 students =
90 × 20
= 1800
Total number of students = 15 + 20
= 35 students
Total scores of the 35 students (Section + Section B) = 1200 + 1800
= 3000
Hence, overall, the approximate mean score for all of the students on the quiz is calculated as
Total score of the students ins section A and B/ Total number of students
= 3000/35
= 85.714285714
Therefore, the approximate mean score for all of the students on the quiz is 85.714285714
Answer: 3(x-3y)
Step-by-step explanation: first you have to take the 3x and split it up so it can make 3(x-3y) then you have to rewrite it to -9 as 3x3 and then factor out common term 3 which would be your final answer 3(x-3y)
