Answer:
the last one im p sure !!!
Answer:
They are parallel lines
Step-by-step explanation:
Firsr you have to put both of the equations in slope intercept form which is y=mx+b and line 1 that would be 4y=3x+12 then you divide the slope and the y-intercept by 4 to get ride of the 4 in front of the y and it would equal y=3/4x+3 and for line 2 you do the same and that put into slope intercept form would be 2y=1.5x-14 so you do the same and divide the slope and the y-intercept by 2 which would equal y=0.75x-7 and 3/4 in decimal form would be 0.75. since the slopes are the same the lines would be parallel
3/7 is equal to 9/21 because when you simplify 9/21 you can divide both 9 and 21 with 3 so you would get 3/7
hope this helps
So the probability she choses a blue marble on the first draw is 8/20 or 2/5 and since she replaces it so the second is 8/20 (2/5) again. Therefore, he chances of choosing 2 blue marbles is .16 or 16%.
