2x - 12 divided by 3 = 7 
12 divided by 3 = 4
2x - 4 = 7
    +4   +4 
2x = 11

Divide each side by 2 
x = 5 1/2

First divide 12 by 3
then we have 2x-4=7
add 4 to both sides to get 2x=12 
divide both sides by 2 to get x=6

A triangular prism container is full of water of 428 cubic cm. The water is 10 cm deep, what is the base area of the container?
Hatshy [7]
<h3>The base area of triangular prism container is 42.8 cubic centimeter</h3>

<em><u>Solution:</u></em>

<em><u>The volume of triangular prism is given as:</u></em>

v = base\ area \times height

Given that,

A triangular prism container is full of water of 428 cubic cm

The water is 10 cm deep

Therefore,

v = 428 cubic cm

h = 10 cm

<em><u>Substituting the values we get,</u></em>

428 = base\ area \times 10\\\\base\ area = \frac{428}{10}\\\\base\ area = 42.8\ cm^2

Thus the base area of triangular prism container is 42.8 cubic centimeter

What is the inverse of the function f(x) = x +3?
Yanka [14]

Answer:

C)h(x) = x-3

Step-by-step explanation:

To find the inverse of a function, switch the "x" and "y" values, then isolate for "x".

f(x) is the y value.

y = x + 3

x = y + 3   Switch x and y

x - 3 = y     Subtract 3 from both sides to isolate

y = x - 3   Change back to function of h

h(x) = x - 3
