Which equation represents a nonlinear function?
Luden [163]
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.

Which of the following expressions represents the least common multiple of 15, 18, and 25?
Virty [35]

Answer:

(2)(3^2)(5^2)

Step-by-step explanation:

we know that

The <u>Least Common Multiple</u> (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers.

we have

15,18 and 25

Decompose the numbers in prime factors

15=(3)(5)

18=(2)(3^2)

25=(5^2)

Multiply common and uncommon numbers with their greatest exponent

so

The LCM is equal to

LCM=(2)(3^2)(5^2)

LCM=450

What is 10/n = 15/45 solved?
Lina20 [59]
The answer would be 3.33333. I think because 10*15= 150. Then you would divide it by 45 and you would get 3.333. If you get it wrong im sorry.

3. I am collecting baseball cards. My goal before I turn 18 is to have 500 cards. When I tumed 10,
vladimir2022 [97]

Based on the scenario given, the equation to describe the situation will be: c + 125 + 89 = 500 and 286 cards need to be collected.

Number of cards given by grandfather = 125 cards

Number of cards that will be given by father = 89 cards

Therefore, based on the information given, the equation to describe the situation will be:

c + 125 + 89 = 500

Therefore, we can then use the equation to calculate the number of cards that need to be collected. This will be:

c + 125 + 89 = 500

c + 214 = 500

c = 500 - 214

c = 286

Therefore, the person needs to collect 286 cards.
