What is the inverse of the function ? *
f(x)=x+4

Answers

Answer 1

Answer:

[tex]f^-1(x)=x-4[/tex]

Explanation:

[tex]f(x)=x+4\\y=x+4\\[/tex]

We first replace f(x) with y.

We then switch x and y.

[tex]x=y+4[/tex]

We then find y in terms of x in our new equation.

[tex]y=x-4[/tex]

We then replace y with  [tex]f^-1(x)[/tex].

[tex]f^-1(x)=x-4[/tex]

It cost Chloe $9.20 to send 92 text messages. How many text messages did she send if she spent $18.00?

Answers

Answer:

180 texts

Explanation:

It cost Chloe $9.20 to send 92 text messages. She spent $18.00 then she send 184 message.

What is message?

Message is defined as a specific communication unit that the source intends for some recipient or set of receivers to consume. A message could aim to inform, persuade, or spread goodwill. The major goal is to make people aware of the situations in the workplace where a message can be utilized to convey normal, repetitive, daily chores, instructions, codes, steps, and procedures.

As given

Initial cost = $9.20

Number of message = 92 text messages

Final cost = $18.00

So the number of message = 92 x 2

                                              = 184 text message

Thus, it cost Chloe $9.20 to send 92 text messages. She spent $18.00 then she send 184 message.

f(x) = -3x + 2. What is the range if the domain is {1, -3, 0, -1}

Answers

Answer:

Range values are -1,11,2,5

Explanation:

f(x) is also known as y.

Plug in domain values for x and find y

-3(1)+2 = -1

-3(-3)+2 = 11

-3(0)+2 = 2

-3(-1)+2 =5

Range values are -1,11,2,5

combine like terms:

8x + 24 = 180

subtract 24 from both sides:

Earth has layers, much like an onion. These layers provide answers to many questions. Earth's crust, the outermost layer, is not entirely one piece. It is broken into sections which resemble a huge jigsaw puzzle. These giant sections are known as plates. They are always on the move, creeping along at a snail's pace. The plates seem to float on top of the mantle, the layer of Earth composed of partially melted rock.2 Have you ever put together a puzzle? The pieces must fit together perfectly in order to form a picture. Alfred Wegener was a German scientist. Over 100 years ago, he discovered something fascinating about a map of Earth. Wegener realized that the continents seem to fit together like the pieces of a jigsaw puzzle. This giant piece of land was called Pangaea. It existed over 250 million years ago. Over time, Pangaea's tectonic plates slowly drifted apart. These plates in their current positions make our seven continents.3 Earth's plates are continually being created or recycled. Scientists have studied the ocean floor. They have discovered ridges of mountains along the bottom of the ocean. These ridges form where two plates have started to move apart. Molten rock from the underlying mantle oozes out. Newly formed rock builds up in the space that has been created by the plates' movement. Plate tectonic theory has also helped scientists explain the deep ocean trenches. These deep ocean trenches are areas where plates are being recycled. This can happen where two plates push together. The crust on the edge of one plate is slowly forced under the other. The plate gets pushed back down into Earth's mantle. It will become molten rock again. This type of area is known as a subduction zone. It forms when continental land masses collide with ocean plates, or when two ocean plates collide with each other.4 On the ocean floor, movement of the plates causes trenches and ridges. Plate movement can do more than that. It can also form mountains on land. When two continental plates push together, there is so much force that the plates buckle. Massive mountain ranges are formed. The friction during crustal movement can sometimes cause earthquakes and tsunamis. 5 The plates on Earth's crust change Earth's surface features in many ways. They had been pieced together in a giant landmass. The plates slowly moved apart to their current locations. The plates will continue to move, forming new rocks and recycling the old.
