Question

Evaluate - 4 + 8 - 3f - 5k Use f = 3 and k = 6.

a) 0
b) -38
c) -41
d) 21

Answer 1

After substituting f = 3 and k = 6 into the expression - 4 + 8 - 3f - 5k and performing the arithmetic, the result is -35, which is not one of the provided answer choices.

Step-by-step explanation:

To evaluate - 4 + 8 - 3f - 5k using f = 3 and k = 6, you first substitute the values of f and k into the expression:

- 4 + 8 - 3(3) - 5(6) = - 4 + 8 - 9 - 30.

Next, you perform the arithmetic operations:

- 4 + 8 = 4,

4 - 9 = -5,

Finally, -5 - 30 gives us -35.

The evaluated expression is -35 which matches none of the provided options (a) 0, (b) -38, (c) -41, (d) 21.
