If f (x) = 2 x + 5 and three-halves are inverse functions of each other and f (x) = 2x + 5, what is
marusya05 [52]

Answer:

See explanation

Step-by-step explanation:

The question has conflicting details

f(x) = 2x + 5

f(x) = 2x + 5 and three halves doesn't sound correct.

So, I will take f(x) as

f(x) = 2x + 5

Next, solve for the inverse function

Replace f(x) with y

y = 2x + 5

Swap x and y

x = 2y + 5

Make 2y the subject

2y = x-5

Make y the subject

y = \frac{x-5}{2}

Replace y with the inverse sign

f^{-1}(x) = \frac{x-5}{2}

So, now we can calculate any value from the original function and from the inverse function.

For instance:

f^{-1}(7) = \frac{7-5}{2} = \frac{2}{2} = 1

f(1) = 2*1 + 5 = 2+5=7

I just need you to answer A for me, I have no clue what the equivalent expression is, please help!
Vladimir [108]
Okay here it is. <span>Part A: </span>
6m + 12 + 42m
48m + 12

<span>Part B: </span>
6m + 12 + 42m  . used distributive property

Part C: Show that your other expression from Part A is equivalent to the given expression by substituting a number for m. (3 points)
6*0 + 12 + 42*0 = 12
<span>48*0 + 12 = 12</span>

Please help me find x thank you so much :)
lesya692 [45]

Answer:

x= 27

Step-by-step explanation:

a triangle always has 180 degrees, therefore:

(3x-17)+(x+40)+(2x-5)= 180

6x+18=180

6x=162

x=162/6

x=27

The population of bacteria in a culture doubles every 14 hours. How long will it take for
Snezhnost [94]

Answer:  22 hours 11 minutes

<u>Step-by-step explanation:</u>

P=P_o\cdot e^{(kt)}\\\\\text{Since the initial population is doubled in 14 hours, then:}\\2P_o=P_o\cdot e^{k\cdot 14}\\2=e^{14k}\\ln\ 2=ln\ e^{14k}\\ln\ 2=14k\\\\\dfrac{ln\ 2}{14}=k\\\\0.0495=k\\\\\\\text{Now that the k-value has been determined, we can find the time when the}\\\text{population is tripled:}\\3P_o=P_o\cdot e^{0.0495t}\\3=e^{0.0495t}\\ln\ 3=ln\ e^{0.0495t}\\ln\ 3=0.0495t\\\\\dfrac{ln\ 3}{0.0495}=5\\\\22.19=t\\\\22\ hrs +0.19\ hrs

22\ hours + \bigg[\dfrac{19}{100}=\dfrac{x}{60}\bigg]\\\\22\ hours + 11\ minutes
