Answer:

x = 15

Step-by-step explanation:

2(x + 12) = 4x - 6 ( divide both sides by 2 )

x + 12 = 2x - 3 ( subtract x from both sides )

12 = x - 3 ( add 3 to both sides )

15 = x

Hello!

In order to solve this equation, you need to divide both sides by 2:

$\bf{2(x+12)=4x-6}$

$\bf{x+12=2x-3}$

Hope it helps! :)

Have a great day!

For which function is f(x) equal to f^-1(x)?

Ilia_Sergeevich [38]

We will find the inverse of the given functions:
y = x + 2 / x-2
(x-2) y = x + 2
-2y + xy = x + 2
-2y + xy = x + 2
x (y - 1) = 2 + 2y
x (y - 1) = 2 (y + 1)
x = 2 (y + 1) / (y - 1)
f (x) ^ - 1 = 2 (x + 1) / (x - 1)
The inverse is different.
f (x) = x + 1 / x-1
y = x + 1 / x-1
(x-1) y = x + 1
-y + xy = x + 1
x (y - 1) = 1 + y
x (y - 1) = (y + 1)
x = (y + 1) / (y - 1)
f (x) ^ - 1 = (x + 1) / (x - 1)
The inverse is the same.
Answer:
f (x) = x + 1 / x-1
f (x) ^ - 1 = (x + 1) / (x - 1)
f (x) = f (x) ^ - 1

If a girl earned $43.65 by working 5 hours in one day , how much would she earn by working 7 hours in one day

Diano4ka-milaya [45]

So you would divide 43.65 by 5 hours (to get 8.73), then you multiply by 7, and your final answer is $61.11

Hope that helps :)

Sunny_sXe [5.5K]

Answer:

Range[4,24,44,64,84,104,124]

Step-by-step explanation:

CHECK THE COMPLETE QUESTION BELOW;

A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs

20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in

pounds can be represented by f x( ) = 20x + 4.

What is the range of the function for this situation?

The range of a function can be defined as the difference between the maximum and minimum function. From the question, we can deduced that the minimum function of X is 0 and no plate is added, and the maximum is 6

The given function is

f(x) = 20x + 4 =

f(0) = 20(0) + 4

= 4

f(6) = 20(6) + 4

= 124

Which means the range is within 4 and 124.

But we are told from the question that Each pair of plates weighs 20 lb, which means there is difference of 20ib each between 4 and 24

Then we can compute the range as [4,124] or (4,24,44,64,84,104,124)
