Answer:

Domain:

,

0

)

∪

(

,

+

∞

)

 

Range:  

(

−

,

+

∞

)

Step-by-step explanation:

y

=

3

x

y

is defined  

∀

x

∈

R

:

x

≠

0

Hence the domain of  

y

is  

(

−

∞

,

0

)

∪

(

0

,

+

∞

)

Now consider:

lim

x->0-

 

y

=

−

∞

and

lim

x->0+

 

y

=

+

∞

Hence the range of  

y

is  

(

−

∞

,

+

∞

)

This can be seen from the graph of  

y

below.

Mhanifa can you please help this is due asap
sleet_krkn [62]

Answer:

<h3>Question 1 </h3>
  • <em>Adjacent angles are supplementary, opposite angles are equal</em>

<u>Find x</u>

  • 62 + 5x + 3 = 180
  • 5x = 180 - 65
  • 5x = 115
  • x = 23

<u>Find y</u>

  • 62 = 3y + 2
  • 3y = 60
  • y = 20
<h3>Question 2</h3>
  • <em>Diagonals bisect each other</em>

<u>Find x</u>

  • 4x = 3x + 7
  • x = 7

<u>Find y</u>

  • 6y = 2y + 16
  • 4y = 16
  • y = 4

Correct choice is A

10 – 7x = 2 - 8x help :)
Rudik [331]
10-7x=2-8x

We move all terms to the left:

10-7x-(2-8x)=0

We add all the numbers together, and all the variables

-7x-(-8x+2)+10=0

We get rid of parentheses

-7x+8x-2+10=0

We add all the numbers together, and all the variables

x+8=0

We move all terms containing x to the left, all other terms to the right

x=-8
