Answer is 2, 5, I believe.

So sorry if I'm wrong.

Answer:

the anstwer is (−2, 5

Step-by-step explanation:

The formula for the y-axis is -x,y so the X have to change for example if the coordinates were 4,5 the reflection of the y-axis will be -4,5

Use the coordinates of the labeled point to find the point-slope equation of the line.

LenKa [72]

For this case we have that by definition, the equation of a line of the point-slope form is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

m: It's the slope

$(x_ {0}, y_ {0})$ : It is a point through which the line passes

To find the slope, we need two points through which the line passes, observing the image we have:

$(x_ {1}, y_ {1}): (3, -5)\\(x_ {2}, y_ {2}): (0,4)\\m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {4 - (- 5)} {0-3} = \frac {4 + 5} {-3} = \frac {9} {- 3} = - 3$

Thus, the equation is of the form:

$y-y_ {0} = - 3 (x-x_ {0})$

We choose a point:

$(x_{0}, y_ {0}) :( 3, -5)$

Finally, the equation is:

$y - (- 5) = - 3 (x-3)\\y + 5 = -3 (x-3)$

Answer:

$y + 5 = -3 (x-3)$

The slowly increasing distance between South America and Africa is due to: a. <u>Seafloor Spreading</u>.
Old Faithful Geyser at Yellowstone National Park in the United States of America acquires its energy from a: b. Hot Spot.
Layered <u>sedimentary rock</u> exposed by erosion can be seen when looking at the Grand Canyon in the United States of America.
Australia is made up of relatively old and thick: d. Continental Crust.
The extremely deep ocean Marianas Trench is a result of: g. Subduction.
<u>Seafloor Crust</u>: found in the Atlantic Ocean between North America and Europe comprises dense and relatively young rock.
The earthquakes that occur in Southern California generally occur above a: f. Fault.

<h3>What is seafloor spreading?</h3>

<u>Seafloor spreading</u> can be defined as a process that involves the formation of new oceanic crust as a result of volcanic activities and an upwelling of molten magma at mid-ocean ridges, as well as a slowly increasing distance (outward movement) from the ridge.

The theory of <u>seafloor spreading</u> was established by Harry Hammond Hess and it can be used to explain in details the slowly increasing distance between South America and Africa which grows from the center.

A <u>hot spot</u> refers to an area deep within Earth's mantle or under the rocky outermost layer of Earth, from which heat rises through convection and acquired as heat energy by a landform.

In the United States of America, you will see a layered <u>sedimentary rock</u> that is exposed by erosion when you view the Grand Canyon.

Furthermore, Australia is made up of relatively old and thick <u>continental crust</u>. Also, <u>subduction</u> causes the formation of extremely deep ocean Marianas Trench.

Describe how the graphs of y=x and y=x-15 related

Sholpan [36]

They have the same slope
in y=mx+b form
m=slope
b=y-intercept
the equations are
y=1x+0 and y=1x-15
the slopes are the same, the y intercepts are the ones that changed
since they have the same slope, they are paralel to each other

Write your own word problem and share it with the group. Then translate your problem into its resulting math equation. What step

Ainat [17]

Step-by-step explanation:

Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.

Example:

A certain number is divided by half, the result is added to itself to give 6, what is the number?

Solution:

- Let the number be x

- Divide x by half:

In word problem, extra caution is to be taken, as misinterpretation can be very chaotic. Dividing a number by 2, is totally different from dividing the number by half.

4 divided by 2 is 4÷2 = 2

4 divided by half is 4÷½ = 4×2/1 = 8

2 and 8 are different, reason to be cautious.

So dividing x by half, we have:

x ÷ 1/2 = x × 2/1 = 2x.

- Now, what we have is

2x + x = 6

Solving this equation, we can obtain the value of x.

2x + x = 6

3x = 6

Dividing both sides by 3

3x/3 = 6/3

x = 2.

Therefore, the solution to the word problem is x = 2.
