Answer:
4x-3y+12=0 is required eqn
Step-by-step explanation:
Let, 3,8 be x1,y1
9,16 be x2,y2
Now,
Eqn of st.line is y-y1 = y2-y2/x2-x1 * (x-x1)
y-8 = 16-8/9-3 * (x-3)
y-8 = 4/3*(x-3)
3y-24 = 4x-12
4x-3y+12=0 is required eqn
The polynomial is the same in standard form
Adjacent angles in parallelograms are supplementary angles thus :



So we know there are 5 red and 12 silver marbles, together making 16 marbles.
This would mean that there is a 5/17 chance of choosing a red marble.
When you do the math to convert 5/17 into a decimal, it turns into being a .29 chance.
Convert .29 into a decimal, and you know that you have a 29% chance of grabbing a red marble.
Hope this helped!
