Answer:

y = 13/3

Step-by-step explanation:

substitute y=2x+5 in x+y = 4

x+2x+5 = 4

3x+5=4

3x= -1

x= -1/3

substitute x= 1-/3 in x+y = 4

-1/3 +y = 4

y = 13/3

Nikki packed unit cubes into a prism, as shown. Which statement about the volume of the box is true?
elena-14-01-66 [18.8K]

See the explanation

<h2>Explanation:</h2>

Hello, recall that you need to write complete questions in order to get exact answers. Here we have a missing diagram so I can help you in a general way. A prism is a three dimensional shape that has two identical ends (flat faces

) and the same cross section all along its length. A cube is a special type of prism having six identical square sides. So the volume of a prism given the length of a side as s is:

V=s^3

For example, suppose we have a box formed by unit cubes as indicated in the figure below, so the length of one side of the blue box will be:

s=1+1+1+1+1+1+1+1=8units

So the volume of the blue box is:

V=8^3 \\ \\ V=512units^3

If f(x) =1/9 x-2, what is f-1(x)?
Sav [38]

Answer:

f^-1(x) = 9(x+2)

Step-by-step explanation:

To find the inverse function, exchange x and y and then solve for y

y = 1/9 x -2

Exchange x and y

x = 1/9 y-2

Solve for y

Add 2 to each side

x+2 = 1/9 y-2+2

x+2 = 1/9y

Multiply each side by 9

9(x+2) = 9*1/9y

9(x+2) = y

The inverse function

f^-1(x) = 9(x+2)
