4x +3y=36
Step-by-step explanation:
Equation of line is (y-y1) = m(x-x1)
(y+4) = (-4/3)(x-12)
3(y+4) = (-4)(x-12)
3y +12 = -4x + 48
4x+3y = 36
Answer:
New avaerage if 2 students (15 year old) left = 13
Step-by-step explanation:
Given:
Average age of 20 students = 13.2
Find:
New avaerage if 2 students (15 year old) left

New avaerage if 2 students (15 year old) left = 234 / 18
New avaerage if 2 students (15 year old) left = 13
