B is the correct answer



\frac{x}{100}  =  \frac{53}{106}  \\ x =  \frac{53 \times 100}{106}  =  \frac{5300}{106}  = 50




good luck

4. Determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Ierofanga [76]

Answer:

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Step-by-step explanation:

Given

Given that the function f(x) and g(x) are inverse functions.

f\left(x\right)\:=\:\frac{1}{3}x\:+\:5

g(x) = 3x - 15

To determine

Let us determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

<u>Determining the inverse function of f(x) </u>

A function g is the inverse function of f if for y = f(x), x = g(y)

y=\frac{1}{3}x+5

Replace x with y

x=\frac{1}{3}y+5

Solve for y

y=3x-15

Therefore,

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Berto has $12 to put gas in his car. If gas costs $3.75 per gallon, which ordered pair relating number of gallons of gas, x, to
Nastasia [14]
Berto can purchase 12/3.75 gallons, this is 3.2 gallons of gas. So the coordinate on this line would be (3.2, 12).
Good Luck! :D

5/6 – 6/12<br><br>I am lost bc I'm not a math person so pls help me?
vovangra [49]

First, we must find the common denominator (12)            ✵

10/12-6/12            ✵                 ✵                              ✵                              ✵

Now, why 10?                                     ✵                   ✵                      ✵

Because we CAN'T just take the denominator and change it; we must change both the denominator AND the numerator:

✵                                      •          -                                      ○          

4/12                  ✧                             ✩                                  ✶            ✺         ✱  

We can simplify, or reduce, this fraction:                  ✱  ✱

1/3              ✩                              ✦                                        ✤

I hope it helps!
