Question

suppose that v(x) = 5x and w(x) = x + 2. which of the following is w(v(7))? a. 37 b. 44 c. 45 d. 35 and 9

Explanation:

Step1: Calcular \( v(7) \)

Dado \( v(x) = 5x \), sustituimos \( x = 7 \):
\( v(7) = 5 \times 7 = 35 \)

Step2: Calcular \( w(v(7)) \)

Ahora, \( w(x) = x + 2 \) y \( v(7) = 35 \), así que sustituimos \( x = 35 \) en \( w(x) \):
\( w(35) = 35 + 2 = 37 \)

Answer:

A. 37
