Answer:

1) 4(x-7)=32

2) \frac{1}{3}x=x-12

3) 10+\frac{x}{2}=-15

4) (3x)-1=5+x

Step-by-step explanation:

Given : Expressions in words.

To find : The expressions value?

Solution :

Let x be the number,

According to question,

1) "Four times the difference of a number and 7 is 32"

\Rightarrow 4(x-7)=32

2) "One third of a number is 12 less than the number itself"

\Rightarrow \frac{1}{3}x=x-12

3) "Ten increased by the quotient of a number and 2 is -15"

\Rightarrow 10+\frac{x}{2}=-15

4) "One less than the product of a number and 3 is 5 more than the number itself"

\Rightarrow (3x)-1=5+x

<u>Part 1)</u> "Four times the difference of a number and 7 is 32"

Let

x--------> the number

we know that

the expressions is equal to

4(x-7)=32

therefore

<u>the answer part 1) is</u>

4(x-7)=32

<u>Part 2)</u> "One third of a number is 12 less than the number itself"

Let

x--------> the number

we know that

the expressions is equal to

\frac{1}{3} x=(x-12 )

therefore

<u>the answer part 2) is</u>

\frac{1}{3} x=(x-12 )

<u>Part 3)</u> "Ten increased by the quotient of a number and 2 is -15"

Let

x---------> the number

we know that

the expressions is equal to

10+ (\frac{x}{2} )= -15

therefore

<u>the answer Part 3) is</u>

10+ (\frac{x}{2} )= -15

<u>Part 4)</u> "One less than the product of a number and 3 is 5 more than the number itself"

Let

x---------> the number

we know that

the expressions is equal to

(3x)-1=5+x

therefore

<u>the answer Part 4) is</u>

(3x)-1=5+x

Please help!!! ive been stuck on this for 30 minutes now!
max2010maxim [7]

Answer:

f^-1 = 4(x-3)

Step-by-step explanation:

If f(x) = 1/4(x) + 3 we ned to find f^-1.

To find the inverse function, we need to solve the equation for "x", as follows:

f(x) = 1/4(x) + 3

y = 1/4(x) + 3

y-3 = 1/4(x)

4(y-3) = x

Now, change the "x" for an "y". And change the "y" for an "x":

4(x-3) = y

The solution is the last one.
