Find the LCM (least common multiple) of the denominators, and use that as the denominator for the two fractions.

Ex.

$\frac{3}{4} +\frac{2}{3}$

LCM (3, 4) is 12

$\frac{9}{12} +\frac{8}{12}$

= $\frac{17}{12}$

Answer:

2.f(x)=2^4x

Step-by-step explanation:

16^x

We can rewrite 16 as 2^4

2^4^x

We know that a^b^c is equal to a^ (b*c)

so 2^(4*x)

2^(4x)

What is the inverse of the function H(x)=3/4x+12

Mrac [35]

Answer:

$h^{-1}$ (x) = $\frac{4x-48}{3}$

Step-by-step explanation:

let y = h(x) and rearrange making x the subject, that is

y = $\frac{3}{4}$ x + 12 ( multiply through by 4 to clear the fraction )

4y = 3x + 48 ( subtract 48 from both sides )

4y - 48 = 3x ( divide both sides by 3 )

$\frac{4y-48}{3}$ = x

Change y back into terms of x, thus

$h^{-1}$ (x) = $\frac{4x-48}{3}$
