Answer:

The value of the expression would be 11.

Step-by-step explanation:

3 (4 - n) + 8

Answer:

 11

Step-by-step explanation:

Let the number is n

Then as per statement of the question

"Eight more than three times the difference of four and a number"

Expression will be [3(4-n)+8]

Now for n = 3

Value of the expression will be [3(4 - 3 ) +8]

                    = [ 3 × 1 + 8 ]

                   = 11

If f(x) =3x-5 them find values of f(3) and f(-7). please explain step by step​
LenKa [72]

Answer:

f(3) = 4

f(-7) = -26

Step-by-step explanation:

Hi there!

f(x) =3x-5

To find f(3), replace every x with 3:

f(3) =3(3)-5\\f(3) =9-5\\f(3) =4

Therefore, f(3)=4.

f(x) =3x-5

To find f(-7), replace every x with -7:

f(-7) =3(-7)-5\\f(-7) =-21-5\\f(-7) =-26

Therefore, f(-7)=-26.

I hope this helps!

Find the additive inverse of each linear expression<br> 1. 3x - 6<br> 2. -9x + 3<br> 3. -4x -8
lubasha [3.4K]

Step-by-step explanation:

G(x) = 2/3 x - 6     switch x and y around and solve for y.

y = 2/3 x - 6

x = 2/3 y - 6

x + 6 = 2/3 y

3/2  x + 9 = y

How do you figure out sales tax?
monitta

Answer:

Step-by-step explanation:

You divide the price with 9.25.

For example, if I wanted to buy a pouch(3.00) and pens(4.59), and the total without tax was 7.59 (add the prices), the tax would be 0.70 because 7.59/9.25=0.70. If I add 0.70 to 7.59, I would have to pay 8.29.

Hope this helps!

What is the inverse of x-2
SCORPION-xisa [38]

Answer:

y = x + 2

Step-by-step explanation:

The expression x-2 is from the equation y = x - 2.

To find the inverse of the equation, <u>switch the "x" and "y" variables</u>, then solve  or <u>isolate for "y"</u>, meaning to separate it from the other numbers.

y = x - 2     Original equation

x = y - 2     Switched "x" and "y" variables

x + 2 = y - 2 + 2     Add 2 to both sides to cancel out '-2' on the side with "y"

x + 2 = y    

y = x + 2     Variable is on left side in standard formatting

To isolate, do the reverse operation for the number you want to get rid of.

On the side with "y", I wanted to get rid of '-2' so I could separate "y" from everything else. '+2' is the reverse operation for '-2'.
