Solve 3x - 12 = 3x + 4<br> REALLY need help with this!!!<br> Please show ALL of your work<br> :)
bazaltina [42]

Answer: It has no solution.


Step-by-step explanation:

3x - 12 - 4 = 3x + 4 - 4

3x - 8 = 3x

3x - 8 - 8 = 3x - 8

we can't subtract 3x-8

Doesn't add up; they need to have one solution or more for it to work.

The table below shows some inputs and outputs of the invertible function f with domain all real numbers.
Ratling [72]

Answer:

{f}^{ - 1} (f(93)) = 93

f(f(7)) =  - 15

Step-by-step explanation:

A function and its inverse has the following properties

{f}^{ - 1} (f(x)) = x

This implies that;

{f}^{ - 1} (f(93)) = 93

From the table,

f(7) =  - 6

This means that:

f(f(7)) = f( - 6)

f(f(7)) =  - 15

Note that: f(7) means the value of f(x) when x=7.

From the table f(x)=-6 when x=7.

That is why f(7)=-6.

Need help on question please!!
Zepler [3.9K]

you'd use the pythagorean theorem.

a^2+b^2=c^2

a is the first leg, b is the second leg, and c is the third leg.

10^2+13^2=c^2

100+169=c^2

269=c^2

take the square root of both sides

16.4=c

16.4cm is your answer!
