Step-by-step explanation:

okay let solve for d elements in d bracket ( Z u X )'

so let do this first ( Z u x ) = ( b,f h,k,p,s,v )' = ( )empty set because all of ( z u x ) is in u our universal set

( ) n y = ( b,f,h )

The sum of 3 consecutive multiples of 4 is 120. Find the numbers.

Vesnalui [34]

Answer:

The required numbers are: 36, 40, 44

Step-by-step explanation:

Let first number = 4x

Second number = 4(x+1)

Third number = 4(x+2)

There sum = 120

We need to find the numbers

We can write:

$4x+4(x+1)+4(x+2)=120\\4x+4x+4+4x+8=120\\12x+12=120\\12x=120-12\\12x=108\\x=\frac{108}{12}\\x=9$

So, we get x = 9

Now, finding the numbers:

first number = 4x = 4(9) =36

Second number = 4(x+1) = 4(9+1) = 4(10) = 40

Third number = 4(x+2) = 4(9+2) = 4(11) = 44

So, The required numbers are: 36, 40, 44

What is the imgae point of (-2,-3) after a translation right 2 units and 4 up units?

kherson [118]

the image point of (-2,-3) after a translation right 2 units and 4 up units is (0,1) .

<u>Step-by-step explanation:</u>

Here we have , to find the image point of (-2,-3) after a translation right 2 units and 4 up units . Let's find out:

Initially we have the point as (-2,-3) , Following transformations are done :

a translation right 2 units :

The point is (-2,-3) , let $(x,y)=(-2,-3)$ . Translation is 2 units right , means there is change in x coordinate by +2 , i.e.

⇒ $(x,y)=(-2,-3)$

⇒ $(x+2,y)=(-2+2,-3)$

⇒ $(x+2,y)=(0,-3)$

a translation 4 up units:

The point is (0,-3) , let $(x,y)=(0,-3)$ . Translation is 4 units up , means there is change in y coordinate by +4 , i.e.

⇒ $(x,y)=(0,-3)$

⇒ $(x,y+4)=(0,-3+4)$

⇒ $(x,y+4)=(0,1)$

Therefore , the image point of (-2,-3) after a translation right 2 units and 4 up units is (0,1) .
