Answer:
54
Step-by-step explanation:
What the shorthand is telling you is wherever you see an x on the right, you put in -8
f(x) = 6(1- x)
f(-8) = 6(1 - - 8)
f(-8) = 6(1+8)
f(-8) = 6*9
f(-8) = 54
The mean of 8 and another number is 13. what is the other number?
Work Shown:
x = the unknown number
The mean of 8 and the unknown number is 13. This indicates we add up 8 and x, then divide by 2, and we'll get 13.
(8+x)/2 = 13
8+x = 2*13 .... multiply both sides by 2
8+x = 26
x = 26-8 .... subtract 8 from both sides
x = 18
As a check,
(8+18)/2 = 26/2 = 13
This shows the mean of {8,18} is 13.
The second number is 18.
Given to us,
First number, [tex]N_f = 8[/tex],
Mean of two numbers, [tex]m = 13[/tex]
Let us assume second number as x,
Also, we know mean is the arithmetic average of given numbers.
[tex]Mean =\dfrac{Sum\ of\ all\ the\ data\ given}{Numbere\ of\ data\ given}[/tex]
[tex]m=\dfrac{8+x}{2}\\\\13=\dfrac{8+x}{2}\\\\13\times 2 = 8+x\\8+x=26\\x=26-8\\x=18[/tex]
Hence, the second number is 18.

Suppose in Loma, Montana the temperature rose from -2.3 degrees Fahrenheit to 8.6 degrees Fahrenheit. What is the change in temperature?
A.10.9 degrees Fahrenheit
B.-10.9 degrees Fahrenheit
C.6.3 degrees Fahrenheit
D.-6.3 degrees Fahrenheit
Explain how to find the change in temperature.
Answer:
A: 10.9
Step-by-step explanation: -2.3 is 2.3 away from zero then add the length from zero to the postive number which in this case is 8.6, therefore the equation is 2.3 + 8.6 = 10.9

in 2013 January there were 360 pupils in school the ratio of boots to girls was 5:4 in February 18 boys were admitted in school how many boys were there in February
Answer:
218
Step-by-step explanation:
this is ratio.
5+4=9. which is the ratio you add it.
5/9×360=200
therefore the number of boys in school during 2013 january is 200 plus admitted boys in February is 200+18=218.
therefore the number of boys in school from january to february is 218.

Answer:
Sample response: Kaycee did not keep lemonade and dollars in corresponding positions in the ratios of the proportion. The proportion should be 12/3=c/9 or it could be written 3/12=9/c. Dollars should be in the same position and cups should be in the same position across ratios.

6.3952 rounded to the nearest tenth
The decimal number 6.3952 rounded to the nearest tenth is 6.40.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, A decimal number 6.3952 and we have to round to the nearest tenth.
To round it to the nearest ten we'll look at the digit at the hundreds place which is 5 so we'll add one to the tens digit and make the digits after that zero.
Therefore, 6.3952 rounded to the nearest is 6.40.

find (g•f)(3) f(x)=3x-2 g(x)=x^2
Answer:
f(x)=3x-2
g(x)=x^2
(g o f)(3)=?
(g o f)(3)=g(f(3))
x=3→f(3)=3(3)-2
f(3)=9-2
f(3)=7
(g o f)(3)=g(f(3))=g(7)
x=7→g(7)=7^2
g(7)=49
Answer: (g o f)(3)=49
OR,if you like this answer can also work
For this case, the first thing we must do is the composition of functions.
We have:
f (x) = 3x-2
g (x) = x ^ 2
(gOf) (x) = (3x-2) ^ 2
We now evaluate the function:
(gOf) (3) = (3 * (3) -2) ^ 2
(gOf) (3) = (9-2) ^ 2
(gOf) (3) = (7) ^ 2
(gOf) (3) = 49
Answer:
(gOf) (3) = 49
Both are same

Graph the line that represents this equation: y+2=1/2(x+2)
Answer:
x=2y+2
Step-by-step explanation:
ur welcome
Answer:
y = 1/2x - 1
Step-by-step explanation:
This formula is currently written in point-slope form (y+ + y1 = m (x + x1). To graph it easier, the first thing you would do is make it slope-intercept form (y=mx + b).
First, distribute the 1/2 into the parenthesis.
1/2(x+2)
1/2x + 1
Then, the equation should look like this: y+2 = 1/2x + 1
The next step is to subtract the 2 from both sides.
It should look like this:
y = 1/2x -1
Graph it by first plotting the y-intercept, -1, on the y-axis, and counting up 1 space and to the right 2 spaces, then drawing a line. I hope this helped!
