The correct answer is:  [A]:  " <span>x(y – 5) = 2 " .
</span>_____________________________________________________
Consider:
_____________________________________________________
Choice:  [A]:  " x(y–5) = 2 " ; 

Divide each side by "x" ;

" [x(y – 5)] / x  = 2/x " ; 

  →  y – 5 = 2/x  ;

Add "5" to each side of the equation:

y – 5 + 5 = 2/x + 5 ;

  →  y = 2/x + 5  ;  not a line;  since one cannot divide by "zero" ; there would be no "point" on the graph at "x = 0".  So, this answer choice:  [A] is correct.
_______________________________________________________
Choice [B]:
 
y -2x -18 = 0 

y - 2x = 18

y = 18 + 2x ;  y = 2x + 18 ; is a line.
_________________________________________________
Choice C)  3y + 12 - 6x = 5 ; 

3y = 5 - 12 + 6x ; 

3y = -7 + 6x ;  3y = 6x - 7 ;  y = 6x/3 - 7/3 ;  y = 2x - 7/3 ;  is a line.
_________________________________________________
Choice:  [D]:

2(y+x) = 0 ;

[2*(y+x)] / 2 = 0/2 ;  y + x = 0 ;  y = -x ;  is a line.

Find the missing side
lisabon 2012 [21]

Answer: 1) The missing length is 40.   2) The missing side is 30 .

Step-by-step explanation:

1)  9^2  + b^2 = 41^2

   81  +  b^2 = 1681

   -81                   -81

   b^2 =  1600

b= 40

2)  24^2 + 18^2 = c^2

 576  + 324 = c^2  

 900 =c^2

c= 30

Maria gathered the data in the table. She finds the line of best fit to be y = 2.78x – 4.4. What is the residual value when x =
luda_lava [24]
The correct answer would be C.0.58

You plug 4 into the line of best fit and get 6.72. This is your predicted value, but the residual is the difference between the actual value and predicted. So you subtract: 7.3-6.72=0.58.

Olve the two-step equation and identify the steps.<br><br> 2 = − 7<br> 4<br> + 1<br> 4<br> x
saul85 [17]

Answer:

x = 5.142

Step-by-step explanation:

<em>2=-74+14x</em>

if you want to make x the subject (work out its value), you need to single out x

1) the first thing that we can do is get rid of the -74

2) do this by adding it on to both sides of the equation. This is called the inverse

<em>2+-74=-72   -74+14x=14x</em>

<em>-72=14x</em>

3) to get x on its own, we now need to get rid of the 14

REMEMBER:<em> 14x = 14×x</em>

4) We do the inverse by dividing both sides by 14

<em>-72÷14=-5.142..</em>.

its surprising that its not an integer

<em>5.142=x</em>

<em>x=5.142 </em>

PLEASE LET ME KNOW IF THIS IS CORRECT

Make a flow chart showing that the triangles below are similar. NO LINKS OR CRAZY LANGUAGES.!!!!!!​
pantera1 [17]

Answer: See the attached image

You have the correct idea for the boxes you've filled out. For the first three boxes in column 1, I would be specific which segments you are dividing. So for instance, in the first box, it would be EG/EB = 55/11 = 5. Then the second box would be EF/EC = 35/7 = 5, and so on. The order of the boxes doesn't matter. The three boxes then combine together to help show that the triangles are similar. Specifically \triangle EFG \sim \triangle ECB. The order of the letters is important to help show how the angles pair up and how the sides pair up. We use the SSS similarity theorem here.

The second problem is the same idea, but we use one pair of congruent angles. So we'll use the SAS similarity theorem this time.
