Answer:
y=4/3
Step-by-step explanation:
I'm guessing, you substitute j with 12 and then you would have 12/4 and that would be 3
Answer:
3 students in blue and 12 in white
Step-by-step explanation:
set 1/6 and 2/3 of it and you need to find that of 18
so you take 2/3*18 and get 12 students
and 1/6*18 and get 3 students
first you need to find the slope of he current equation by changing it to y=mx+b
3x-2y=9 subtract 3x from both sides
-2y=-3x+9 divide both sides by -2
y+3/2x-9/2 Your slope of the existing is 3/2 or 1 1/2
a perpendicular line has the opposite reciprocal slope so 3/2 would be -2/3
-3 is your y intercept. now you can make your equation
y=-2/3x-3
