These steps may help you out!

8 1/2 = 17/2

4 1/2 = 9/2

To get this you do⬆8(2) =16 + 1 = 17/2 ; 4(2) = 8 + 1 = 9/2

Change the problem to:

17/2 (9/2)

17(9)/2(2) = ?

So, 17(9) / 2(2) = 153 / 4

153 / 4 as a mixed fraction/number: 38 1/4

If fx = 3x over 5 +3 which of the following is the inverse

Alborosie

Answer:

f^(-1)(x) = -3x/(3x-3)

Step-by-step explanation:

1) replace f(x) by y

● y = 3x/(5x+3)

2) exchange x and y

● y = 3x/(5x+3)

● x = 3y / (3y +3)

3) solve for y

● x = 3y / (3y +3)

● x (3y +3) = 3y

● 3xy + 3x = 3y

● 3xy - 3y = -3x

● y (3x - 3) = -3x

● y = -3x /(3x-3)

4) replace y with f^(-1)(x)

● y = -3x/(3x-3)

● f^(-1)(x) = -3x/(3x-3)

Use the formula . Find t for r = 33.2 m/h and d = 375.16 m.

Butoxors [25]

$\boxed{t=11.3h}$

<h2>Explanation:</h2><h2></h2>

In this problem we have the following data:

$r:speed \\ \\ d:distance \\ \\ t:time \\ \\ \\ r=33.2m/h \\ \\ d=375.16m \\ \\ \\ So \ our \ goal \ is \ to \ find \ t$

Speed, time and distance are related with the following formula:

$r=\frac{d}{t} \\ \\ \\ Solving \ for \ t: \\ \\ t=\frac{d}{r} \\ \\ t=\frac{375.16}{33.2} \\ \\ \boxed{t=11.3h}$
