Question

Which two expressions are equivalent to f (4 + 5)? Select all that apply.

a. 2
b. 20f
c. 44+ 5
d. 97 + 4f + 5f

Answer 1

To find the equivalent expressions to f(4 + 5), substitute 4 + 5 into the function f. The equivalent expressions are 44 + 5, which simplifies to 49.

Step-by-step explanation:

To find the equivalent expressions to f(4 + 5), we can substitute the expression 4 + 5 into the function f. This gives us:

f(4 + 5) = f(9)

Therefore, the equivalent expressions are:

1. a. 2: This expression is not equivalent to f(4 + 5).
2. b. 20f: This expression is not equivalent to f(4 + 5) as it includes the variable f.
3. c. 44 + 5: This expression is equivalent to f(4 + 5) as it simplifies to 49.
4. d. 97 + 4f + 5f: This expression is not equivalent to f(4 + 5) as it includes the variables f.
