Answer:

6

Step-by-step explanation:

3x+12=36−x

Step 1: Simplify both sides of the equation.

3x+12=36−x

3x+12=36+−x

3x+12=−x+36

Step 2: Add x to both sides.

3x+12+x=−x+36+x

4x+12=36

Step 3: Subtract 12 from both sides.

4x+12−12=36−12

4x=24

Step 4: Divide both sides by 4.

4x/4 = 24/4

x=6

Answer:

x=6

➷ The formula for volume of a cylinder is:

\pi r^2h

The radius is half the diameter

Radius = 8/2 = 4

Substitute the values in:

\pi (4)^2(12)

Surface area = 192\pi

2. A function g(x) is defined by the diagram shown below.
skad [1K]

Answer:

Step-by-step explanation:

diagram attached represents a function g(x).

Circle (1) (circle on the left) represents the set of domain (input values) and circle (2) represents the range (output values).

a). For input value x = 7, out put value of the function is y = 9.

   Therefore, g(7) = 9 will be the answer.

b). Range of the function g(x) is the set of output values.

    Range: {12, 9, 9, 17}

c). Inverse of the function g(x) will have,

   Domain: {12, 9, 9, 17}

   Range: {4, 7, 10, 15}

   For input value of x = 9, there are two output values y = 7, 10.

   Since, "a function can't have two output values for the same input value".

   Therefore, inverse of the function g(x) will not represent a function.
