Using the rule y = 3x + 4, find the value of y when x is 2. a) 9 b) 10 c) 11 d) 12 using the rule y = 8x + 5, find the value of y when x is 6. a) 19 b) 43 c) 50 d) 53 if y = 3x + 5, what is the value of y when x = 12? a) 17 b) 20 c) 31 d) 41 use substitution to determine whether the value for x is a solution for the equation. 3x + 10 = 25 x = 5 5x − 10 = 25 x = 6 6x − 18 = 6 x = 4 4x + 12 = 40 x = 7 8x + 12 = 28 x = 3

option B

option D

option D

Correct

incorrect

correct

correct

incorrect

Step-by-step explanation:

1) y = 3x + 4    with  x = 2

y = 3(2) + 4= 10   option B

2) y = 8x + 5    with  x = 6

y = 8(6) + 5= 53   option D

3) y = 3x + 5    with  x = 12

y = 3(12) + 5= 41   option D

Use substitution to determine whether the value for x is a solution for the equation

3x + 10 = 25    With x = 5

3(5) + 10 = 25      it is correct

5x − 10 = 25    With x = 6

5(6) − 10 = 25     it is not correct

6x − 18 = 6     With x = 4

6(4) − 18 = 6     it is correct

4x + 12 = 40     With x = 7

4(7) + 12 = 40    it is correct

8x + 12 = 28     With x = 3

8(3) + 12 = 28   it is not correct

answer: 140
