We evaluate Separately.

Let x = 5

f(5) = 2(5) + 3

f(5) = 10 + 3

f(5) = 13

Now let x = -3.

f(-3) = 2(-3) + 3

f(-3) = -6 + 3

f(-3) = -3

Answer: Choice C

Answer:

C. f(5) = 13 and f(-3) = -3

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 2x + 3

x = 5

x = -3

<u>Step 2: Evaluate</u>

x = 5

  1. Substitute:                    f(5) = 2(5) + 3
  2. Multiply:                        f(5) = 10 + 3
  3. Add:                              f(5) = 13

x = -3

  1. Substitute:                    f(-3) = 2(-3) + 3
  2. Multiply:                        f(-3) = -6 + 3
  3. Add:                              f(-3) = -3

Answer:

The conclusion "T" logically follows from the premises given and the argument is valid

Step-by-step explanation:

Let us use notations to represent the steps

P: I take a bus

Q: I take the subway

R: I will be late for my appointment

S: I take a taxi

T: I will be broke

The given statement in symbolic form can be written as,

(P V Q) → R

S → (¬R ∧ T)

(¬Q ∧ ¬P) → S

¬R

___________________

∴ T

PROOF:

1. (¬Q ∧ ¬P) → S                Premise

2. S → (¬R ∧ T)                  Premise

3. (¬Q ∧ ¬P) → (¬R ∧ T)    (1), (2), Chain Rule

4. ¬(P ∨ Q) → (¬R ∧ T)      (3), DeMorgan's law

5. (P ∨ Q) → R                   Premise

6. ¬R                                 Premise

7. ¬(P ∨ Q)                        (5), (6), Modus Tollen's rule

8. ¬R ∧ T                          (4), (7), Modus Ponen's rule

9. T                                   (8), Rule of Conjunction

Therefore the conclusion "T" logically follows from the given premises and the argument is valid.

Answer:

d^2 = 30^2 + 12^2

e^2 = d^2 + 8^2

e^2 = 30^2 + 12^2 + 8^2

e = √(30^2 + 12^2 + 8^2) = 33.3 ft
