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.

Complete question;

Evaluate each expression for the given values.

1. (a) x + 7 for x = 2

(b) y - 7 for y = 10​

(c )-2h - 7 for h =2.
