Question

If f(x) = 7 + 4x and g(x)=1/2x, what is the value of (f/g)(5)
?

Answer 1

hyyy ur answer is here......

Answer 2

$Given \: f(x) = 7 + 4x \: and \: g(x) = \frac{1}{2x}$

$\Big( \frac{f}{g} \Big)(x) \\= \frac{f(x)}{g(x)} \\= \frac{7+4x}{\frac{1}{2x}} \\= 2x(7+4x) \: --(1)$

$The \: value \: of \: \Big(\frac{f}{g}\Big) (5) \\=2\times 5 ( 7 + 4 \times 5 ) \\= 10( 7 + 20) \\= 10 \times 27 \\= 270$

Therefore.,

$\red{The \: value \: of \: \Big(\frac{f}{g} \Big)(5)}\green {= 270}$
