Answer:

y = -2x + 8

Step-by-step explanation:

The point slope form of an equation is written as

y = mx + c              ...............(i)

Where m is the slope and c is the constant

Now we Know that the equation is

y + 2 = -2(x-5)

and the given points are

m= -2

x = 5

and y= -2

Putting these values in equation (i) to find the value of c

y = mx + c

it becomes

-2 = -2(5) + c

-2 = -10 + c

Adding 10 on both sides

-2 + 10 = -10 + 10 + c

8 = c

or c=8

Now we have the values of m and c

where m= -2 and c = 8

Point slope form of an equation is

y = mx + c

putting the values of m and c to get equation in slope intercept form is

y = (-2)x + 8

or

y = -2x + 8


Other method:

The given point slope form is

y + 2 = -2(x-5)

We have to change it in y= mx + c      form

so solving it

y + 2 = -2x + 10

Subtracting 2 from both sides

y + 2 -2 = -2x + 10 -2

y = -2x + 8

which is same is

y=mx + c

so the required equation is

y = -2x + 8

What is the difference between Laplace Transform and fourier Transform?
marta [7]

Real time mapping of a function to a new function is known as Fourier transforms. The new mapped function is defined for an interval of (-∞, ∞).

<span>While the Laplace transform is the counterpart, in which a function is mapped to a new function on complex plane. Functions defined for span t≥0 are used by Laplace transformation. </span>

What is the value of |B| – |A|? <br><br> A. 4<br> B. –10<br> C. 10<br> D. –4
Elena L [17]

Answer:

A. 4

Step-by-step explanation:

We can look at the number line and find B and A

we get

B=-7

A=3

now, we can find |B| and |A|

|B|=|-7|=7

|A|=|3|=3

now, we can find

|B|-|A|

now, we can plug values

|B|-|A|=7-3

|B|-|A|=4

So,

option-A
