Answer:

7/12

Step-by-step explanation:

To find the probability of drawing a blue marble you need to find how many marbles there are in total.

So you have to add 3 red marbles, 7 blue marbles, and 2 green marbles to get the total.

So 3 + 7 + 2 = 12

There are 12 marbles in total so now you have to find how many blue marbles there are.

There are 7 blue marbles out of 12 marbles.

Now you have to put this as a fraction to see if it can be simplified.

7/12 cant be simplified, so the probability of drawing a blue marble is 7/12.

Help me pls

I think you can find it graphically by points through a table you create like:

let x = 0, and find the value of y

for example for the first equation when we let x = 0 you find y = 6 and be in the form of (0,6) then draw them or you can let x = -2 or -3 , etc as you like

to be more accurate you can find 3 pionts and start graphing them

these two equations are straight lines and they will intersect in a point
