Answer:
y = 12x + 9
Step-by-step explanation:
you triple 4x and just add nine because the y intercept is zero

Answer:
7/19
Step-by-step explanation:
In order to find the probability that two events happen in a sequence you simply have to multiply the probability of each individual event together. Since the probability of the sequence is given to us as well as the probability of drawing the first green jelly bean, this means we need to divide the first probability by the probability of the sequence to get the probability of the second event. Basically, reversing the process. Dividing two fractions, we simply divide the numerators by each other and then the denominators by one another.

Therefore, the probability of picking the second green jelly bean is 7/19
Answer: Choice A) 9/45 and 8/40
------------------------
If you divide both top and bottom of 9/45 by the GCF 9, you get 1/5
If you divide top and bottom of 8/40 by the GCF 8, you also get 1/5
So the original fractions must be the same
------------------------
Another way to check is to use a calculator and see that 9/45 = 0.2 and 8/40 = 0.2, so 9/45 = 8/40
Or you can subtract the fractions and you should end up with 0, so, 9/45 - 8/40 = 0
-------------------------
You can also set up a proportion and cross multiply
9/45 = 8/40
9*40 = 45*8
360 = 360
The last equation is true, so the first equation must be true
