The correct answer is:   " 2 " .

_______________________

    →  6 over "2" equals 3 .

_______________________

Explanation:

_______________________

The question asks:  " 6 over {what value?} equals "3" ?

Solve for the "unknown value".

_______________________

To solve:

Let "x" represent the "unknown value".

_______________________

→   "  \frac{6}{x}  = 3 " ;  Solve for "x" .

→  Multiply each side of the equation by "x" ;   as follows:

→  x * \frac{6}{x}  = 3 * x  ;

_______________________

→  The 2 (two) "x" variables on the "<u><em>left-hand side</em></u>" of the equation cancel out;

    →  {since:  " \frac{x}{x} = 1 " ;  

    →  {since any value, divided by that same value, is equal to "1" ;

           →   {assuming that the value is not "zero" .} ;

_______________________

→  to get:

  " 1 * 6  = 3 * x " ;  

→  which we can simplify and rewrite; as follows:

  "  6 = 3x " ;

↔  " 3x = 6 " ;

Now, we can divide EACH SIDE of the equation by "3" ;

   to isolate "x" on one side of the equation;  & to solve for "x" ; as follows:

    →  3x / 3  =  6 / 3  ;

to get:

_________________________

   →   x  = 2 .

_______________________

The answer is:  " 2 "  .

_______________________

  →  6 over "2" equals 3 .

Hope this helps!

ANSWER ASAP PLS 20 POINTS! Which graph represents the piecewise defined function? y= {3 if x&lt;-2 0 if x=1 -1 if x&gt;1
Otrada [13]

Answer:

It is the third option. (the one which has a black point at X=1, Y=1)

Step-by-step explanation:

For simplicity what you should do is, you should satisfy the second condition that is, y=0 if x=1.

Here only the third option is satisfying this condition.

Whenever there is is a white circle or a white point it means that the point does not satisfy the condition and the the function is not defined at that point. And the black point means that the circle is defined at that point and satisfies the condition.

Henceforth, the correct answer is the third option.

Ben was in charge of ordering 3636 pizzas for the office party. He ordered three types of​ pizza: cheese,​ pepperoni, and suprem
shutvik [7]

Answer:

Ben bought 11 cheese pizzas, 16 pepperoni pizzas and 9 supreme pizzas

Step-by-step explanation:

We can solve this problem with a equation system. I will abbreviate the amount of cheese pizzas he buyed as C, the amount of pepperoni ones as P, and the amount of supreme ones as S. I will also remove the $ notation

The system is given as follows

  • C+P+S = 36
  • 8C + 11P + 14S = 390
  • 11P = 2*(8C) = 16C

We can easily replace 11P with 16C in equation 2, obtaining

8C + 16C + 14S = 390

24C + 14S = 390

S = (390- 24C)/14 = 195/7 - 12/7 C

Note that, also from equation 3, we have that

11P = 16 C

P = 16/11 C

Now, we can obtain the value of C using equation 1 replacing S and P with the founded values

C+P+S = 36

C + 16/11 C + 195/7 - 12/7 C = 36

C + 16/11 C - 12/7 C = 36-195/7 = 57/7

Taking C as common factor we obtain

C (1+16/11-12/7) = 57/7

C * 57/77 = 57/7

C = (57/7) / (57/77) = 11

Now, we replace this value in the formula we obtain for P and S

P = 16/11 * C = 16/11 * 11 = 16

S = 195/7 - 12/7 * 11 = 63/7 = 9

Now, we verify:

  • C+P+S = 11+16+9 = 36
  • 8C + 11P + 14S = 8*11 + 11*16 + 14*9 = 88 + 176 + 126 = 390
  • 2(8C) = 2*88 = 176 = 11P

Thus, Ben bought 11 cheese pizzas, 16 pepperoni pizzas and 9 supreme pizzas.

The polynomial is a difference squares. Use the formula a^2 -b^2=(a+b)(a-b) to factor completely. 81x^2-49 the value of a is the
AnnZ [28]

Answer: (9x)^{2}-(7)^{2}=(9x-7)(9x+7)

Step-by-step explanation:

1. By definition you have that the difference of squares is:

a^{2}-b^{2}=(a+b)(a-b)

2. Given the polynomial:

81x^{2}-49

You can identify that there are two terms whose signs are different and they are perfect squares.

3. Therefore, you have:

 81x^{2}-49=(9x)^{2}-(7)^{2}=(9x-7)(9x+7)
