The unknown number will be 5 if we add two to twice a number, the result is twelve.
Let the unknown number be x.
Then the twice of the known number be 2x.
According to the given question.
If we add two to twice a unknown number, the result is twelve.
So, from the given scenario we can say that
2 + 2x = 12
Now we have a linear equation in one variable 2 + 2x = 12 and we have to solve it for x which gives us the unknown number.
Therefore,
2 + 2x = 12
⇒ 2x = 12 - 2 (subtracting 2 from both the sides)
⇒ 2x = 10
⇒ x = 10/2
⇒ x = 5
Hence, the unknown number will be 5 if we add two to twice a number, the result is twelve.

Answer: 2 4/5, 3 2/3, 5 2/3, 2 1/2, 3 1/3 part2; 9/2, 49/5,
Step-by-step explanation:
Find the value off(5) for each function
f(h) = - h/10
f(m)=1-4(m/2)
f(m)=2(m-3)
The value of f(5) for each function provided in the reference picture attached hereby with the question statement are as follows:
13. f(5) = 21
14. f(5) = -12
15. f(5) = 20
16. f(5) = (-1/2)
17. f(5) = (-9)
18. f(5) = 4
As per the reference picture attached hereby with the question statement, we are provided with 6 functions.
We are required to find the value of f(5) for each function.
To solve this question, we simply have to replace the the variable of individual functions with 5 and then, perform the operations as per the function to obtain our desired answer.
Starting with [tex][f(x)=6+3x][/tex], substituting (x = 5) in the equation, we will get,
[tex]f(5)=6+(3*5)\\or, f(5)=6+15\\or,f(5)=21[/tex]
Substituting (x = 5) in the second function [tex][f(x)=-2(x+1)][/tex], we get,
[tex]f(5)=-2(5+1)\\or, f(5)=-2(6)\\or,f(5)=-(2*6)\\or, (5)=-12[/tex]
Substituting (x = 5) in the third function [tex]f(a)=[3(a+2)-1][/tex], we get,
[tex]f(5)=[3(5+2)-1]\\or, f(5)=[(3*7)-1]\\or,f(5)=(21-1)\\or,f(5)=20[/tex]
Substituting (x = 5) in the fourth function [tex][f(h)=(\frac{-h}{10})][/tex], we get,
[tex]f(5)=(\frac{-5}{10})\\ or,f(5)=\frac{-1}{2}[/tex]
Substituting (x = 5) in the fifth function [tex]f(m)=[1-4(\frac{m}{10})][/tex], we get,
[tex]f(5)=[1-4(\frac{5}{2})]\\ or,f(5)=[1-(\frac{4*5}{2})]\\ or, f(5)=[1-(2*5)]\\or,f(5)=(1-10)\\or,f(5)=(-9)[/tex]
Finally substituting (x = 5) in the last function [tex]f(m)=[2(m-3)][/tex], we get,
[tex]f(5)=[2(5-3)]\\or,f(5)=(2*2)\\or,f(5)=4[/tex]

(gof) (4) = 9
Hence, option A is true.
Step-by-step explanation:
f(x)=-x³
g(x)=|1/8x -1|
(gof) (4) = g{f(4)}
First wee need to determine f(4)
f(4)=-(4)³
= -64
so
(gof) (4) = g{f(4)} = g(-64)
= [tex]\left|\frac{1}{8}\left(-64\right)-1\right|[/tex]
[tex]=\left|-\frac{1}{8}\cdot \:64-1\right|[/tex]
[tex]=\left|-8-1\right|[/tex]
[tex]=\left|-9\right|[/tex]
[tex]\mathrm{Apply\:absolute\:rule}:\quad \left|-a\right|=a[/tex]

Thus,

A fishing shop charges $8 to rent fishing gear and $35 per hour to rent a boat Write a function to model the cost, y, to rent fishing gear and a boat for x hours.
Answer:
y= 35x + 8
Step-by-step explanation:
the $35 is an hourly charge so it goes with x and the $8 is a one time charge so it just gets added on
The required function is y = 35x + 8 to model the cost, y, to rent fishing gear and a boat for x hours.
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
We have been given that a fishing shop charges $8 to rent fishing gear and $35 per hour to rent a boat.
According to the given situation, we can write the function as:
⇒ y = 35x + 8
Here the $35 is an hourly rate, so it corresponds to x, and the $8 is a one-time charge, so it is simply put on.
Therefore, the required function is y = 35x + 8 to model the cost, y, to rent fishing gear and a boat for x hours.

X The temperature, C, in degrees Celsius recorded by a city park's weather station between midnight and 7:00 a.m. could be represented as a linear function of the number of hours after midnight, t. The temperature at 1:30 a.m. was – 4.2°C and was -8.6°C at 7:00 a.m. Which equation could be used to represent this function? (1 point) O C (t) = -0.8t – 4.2 OC (t) = -1.25t - 8.6 OC (t) = -0.8t - 3 OC (t) = -1.25t - 4.2
Answer:
C(t) = -0.8t - 3
Step-by-step explanation:
We are told that the temperature at 1:30 a.m. was – 4.2°C and was -8.6°C at 7:00 a.m.
Thus, difference in temperature is;
ΔT = -8.6°C - (-4.2°C)
ΔT = -8.6°C + 4.2°C
ΔT = -4.4°C
Now, number of hours between 1:30 a.m and 7:00 a.m is 5.5 hours.
Thus, average temperature per hour is;
-4.4/5.5 = -0.8°C/h
Now, since C is represented as a linear function of the number of hours after midnight, t.
Then the linear function is -0.8t + x = C(t)
Let's find x.
After 1.5 hours, we have -4.2°C. Thus;
-0.8t + x = -4.2
-0.8(1.5) + x = - 4.2
-1.2 + x = -4.2
x = -4.2 + 1.2
x = -3
Thus, the linear relationship is now;
C(t) = -0.8t - 3

On a space shuttle mission a certain experiment is started two days 14 hours and 30 minutes into the mission the experiment takes one day 21 hours and 47 minutes to run when will the experiment be completed give your answer in days hours and minutes into the mission work with a sort of expanded form
The experiment will be completed in 4days + 12hours + 17min .
In the given question
The experiment was started 2days + 14hours + 30min ago
It will take 1day + 21hours + 47min more to complete the experiment .
The total time taken to run the experiment is
= (2days + 14hours + 30 min) + (1day + 21hours + 47min)
On adding the like terms we get
= (2+1)days + (14+21)hours + (30+47)min
=3 days + 35hours + 77min ...(i)
We know that
24 hours = 1 day
So , 35hours can be written as 24hours + 11hours.
35hours = 24hours + 11hours ...(ii)
We also know that
60 min = 1hour
So , 77min can be written as 1hour + 17min
77min = 60min + 17min
77min = 1hour + 17min ...(iii)
Substituting the value of equation (ii) and (iii) in (i) we get ,
Total time = 3 days + 24hours + 11hours + 1hour + 17min
=3 days + 1day + 11hours + 1hour + 17min ...(as 24hours = 1day )
On adding the like terms we get
= 4days + 12hours + 17min
Therefore , the experiment will be completed in 4days + 12hours + 17min .
