Si f(x) es igual a raiz de x al cuadrado menos 16 determinar f(5),f(4),f(6),f(3)
Nadusha1986 [10]

Aplicando la función, los valores numéricos son :

f(5) = -11

f(4) = -12

f(6) = -10

f(3) = -13

La función es dada por:

f(x) = (\sqrt{x})^2 - 16  = x - 16

Para los valores numéricos, reemplazamos x, luego:

f(5) = 5 - 16 = -11

f(4) = 4 - 16 = -12

f(6) = 6 - 16 = -10

f(3) = 3 - 16 = -13

Please help<br><br><br>A) x= -4 and 4<br><br>B) x=4 and 6<br><br>C) x=2 and 8<br><br>D) no solution
Neporo4naja [7]

Answer:

No solutions

Step-by-step explanation:

|-2x-10| + 4 = 2

Subtract 4 from each side

|-2x-10| + 4-4 = 2-4

|-2x-10|  = -2

The absolute value is negative so there are no solutions.

Absolute values are always positive, so they cannot be negative.

podryga [215]

Answer:

3x^7 / y

Step-by-step explanation:

√63x^15y^9/√7xy^11

= √ [(63/7) x^(15-1) y^(9-11)

= √9x^14y^-2

= √9x^14 / y^2

Factor completely. 6y^2-5y+1
Deffense [45]

Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 6</span> • -1 = -6</span> 

Step-2 : Find two factors of  -6  whose sum equals the coefficient of the middle term, which is  <span> -5 </span>.

<span>     -6   +   1   =   -5   That's it</span>


Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -6  and  1 
                     <span>6y2 - 6y</span> + 1y - 1

Step-4 : Add up the first 2 terms, pulling out like factors :
                    6y • (y-1)
              Add up the last 2 terms, pulling out common factors :
                     1 • (y-1)
Step-5 : Add up the four terms of step 4 :
                    (6y+1)  •  (y-1)
             Which is the desired factorization

Final result :<span> (y - 1) • (6y + 1)</span>
