Find the value of a & b​

a = 23

b = 10

Step-by-step explanation:

The general formula is

y = 3x +  5

Just to check, let x = 2

y = 3*2 + 5

y = 6 + 5

y = 11

And a confirmation check

x = 3

y = 3*3 + 5

y = 9 + 5

y = 14

So for a

x = 6

y = 6*3 + 5

y = 18 + 5

y = 23

For b, you know y

35 = 3x + 5

- 5           -5              Subtract

30 = 3x                       Divide by 3

30/3 = 3x/3

x = 10

The values of the variables a and b are:

a = 23

b = 10

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
