The value of the expression (x + 7) when (x = 2) is 9.
The value of the expression (y - 7) when (y = 10) is 3.
The value of the expression (-2h - 7) when (h = 2) is -11.
To evaluate the given expressions for the given values, we can substitute the given values into the expressions.
a) For the expression (x + 7) when (x = 2), we substitute (x = 2) into the expression:
[2 + 7 = 9]
Therefore, the value of the expression (x + 7) when (x = 2) is 9.
b) For the expression (y - 7) when (y = 10), we substitute (y = 10) into the expression:
[10 - 7 = 3]
Therefore, the value of the expression (y - 7) when (y = 10) is 3.
c) For the expression (-2h - 7) when (h = 2), we substitute (h = 2) into the expression:
[-2(2) - 7 = -4 - 7 = -11]
Therefore, the value of the expression (-2h - 7) when (h = 2) is -11.
