A=1/2h (b+c) solve for b

1 answer:

8 0

A=1/2h(b+c)
times both sides by 2/1
2A=h(b+c)
divide both sides by h
$\frac{2A}{h}$ =b+c
minus c from both sides
$\frac{2A}{h}$ -c=b

Step-by-step explanation:

9$ x 71 hours (rewritten) 9x 71 = 639

plus the commission

10% x 1,901$ (rewritten) .1 x 1,901 = 190.1

639 + 190.1 = 829.1

If m(x) =x+5/x-1 and n(x) =x-3 which function has the same domain as (m.n)(x)

Travka [436]

Answer:

Step-by-step explanation:

m (x) = (x+ 5) / (x -1) and n(x) = x - 3.

$m(x) = \dfrac{x+5}{x-1}$

Hence

$m(n) = \dfrac{n+5}{n-1}$

but n is a function and n = x-3. Now, replace value of n on m (n)

$(m(n))= \dfrac{(x-3)+5}{(x-3)-1}$

simplify it

$(m\bullet n)(x) =\dfrac{x+2}{x-4}\\$

since (m . n) (x) is a fraction function, its domain will be all x such that the denominator is NOT 0. That is

$x-4\ne 0\rightarrow x\ne 4$

among options, only C has the same denominator with $(m\bullet n)(x)$

Hence their domains are the same.
