Question

Two less than the product of a number and three Evaluate when f = 4.5.

Answer 1

Complete question :

two less than the product of a number and three Evaluate when f = 4.5.

Evaluating an Algebraic Expression Write and evaluate the expression shown on the left. Then, check all that apply. Write the expression as 2 – 3f. Write the expression as 3f – 2. Write the expression as 2f – 3. The value when f = 4.5 is 6.75. The value when f = 4.5 is 6. The value when f = 4.5 is 11.5.

Answer:

3f - 2

The value when f = 4.5 is 11.5.

Explanation:

2 less than the product of a number and 3

Let the number = f

Product of number and 3 = f * 3 = 3f

2 less than the product :

3f - 2

If the value of f = 4.5

Then, substituting f = 4.5 in the expression :

We have :

3(4.5) - 2

13.5 - 2

= 11.5
