Find f(-3) for f(x) = 4(2)^x.<br> ОА. 1/8<br> O B. -32<br> O C. -24<br> OD. 1/2
Ipatiy [6.2K]

Answer:

D

Step-by-step explanation:

using the rule of exponents

a^{-m} = \frac{1}{a^{m} }

substitute x = - 3 into f(x)

f(- 3) = 4((2)^{-3} = 4 × \frac{1}{2^{3} } = 4 × \frac{1}{8} = \frac{1}{2}

Paguei 74,00 por uma bolsa e uma sandália. A bolsa foi 23,00 mais barato q a sandália. Qual o preço da sandália?
alukav5142 [94]

Responda:

48,5

Explicação passo a passo:

Dado que:

Custo total de bolsa e sandália = 74,00

Deixei :

Custo da sandália = x

Custo da bolsa = x - 23

Preço da sandália:

x + (x - 23) = 74

x + x - 23 = 74

2x - 23 = 74

2x = 74 + 23

2x = 97

x = 97/2

x = 48,5

Portanto, custo da sandália, x = 48,5
