Answer: (4,3)


Step-by-step explanation:

1. In this method you must solve one of the equation for one of the variables and substitute it into the other equation to find the other variable. Then, substitute the value of that variable into one of the original equation to obtain the value of the other one.

2 You have that:

y=2+1/4x

3. Then, you can substitute it into the other equation and solve for x:

3x-5(2+1/4x)=-3\\3x-10-5/4x=-3\\7/4x=7\\x=4

4. Now you can obtain y:

y=2+1/4x

y=2+1/4(4)\\y=3

5. The answer is:

(4,3)

Ipatiy [6.2K]

Answer:

The probability is 10/121

Step-by-step explanation:

In this question, we are tasked with calculating probability.

The probability to be calculated is that we have an ordered selection of picking a red marble after which we pick a yellow marble.

Firstly let us know the total number of marbles we have. That will be 4 + 5 + 2 = 11 marbles

Probability of picking a red marble will be 5/11 while the probability of picking a yellow marble will be 2/11

Now, the probability of picking a red marble before a yellow marble will be mathematically equal to; P(r) * P(y) = 5/11 * 2/11 = 10/121
