Multiple choice
1. 2(y + 1) for y = 2 (1 point)
A. 6
B. 5
C. 7
D.8
Just replace y by 2.
2 • ( 2 + 1 ) = 2 • 3 = 6
To find the value of 2(y + 1) for y = 2, substitute y = 2 into the expression:
2(2 + 1) = 2(3) = 6
Therefore, the answer is A. 6.
To solve this problem, we need to substitute the value of y given in the equation 2(y + 1) for y. For y = 2, the equation becomes:
2(2 + 1)
To simplify, we perform the operation inside the parentheses first by adding 2 and 1:
2(3)
Next, we multiply 2 by 3:
6
Therefore, the answer is A. 6.
