I'd stay this expression is already in standard form, although you could rewrite it as   -(<span>-4x^2-12x+1).

You could rewrite   </span><span>-4x^2-12x+1    by completing the square:

-4(x^2 + 3x                    )                         +1  becomes

-4(x^2 + 3x + [3/2]^2     )       - [3/2]^2       + 1, or

-4(x + 3/2)^2           + 1 - 9/4,    or

-4(x+3)^2      -5/4    (final form)     The graph would be that of a parabola with vertex at (-3, -5/4).  This parabola would open down and would be vertically stretched by a factor of 4.</span>

Sauron [17]

Answer:

(f ο g)(-1) = 1

Step-by-step explanation:

Given

      f(x) = \frac{8}{x+2}    

     g(x) = 4 x^{2} +2

f ο g)(-1) = f(g(-1) = f(4(-1)² + 2)

                          = f(6)

                         = \frac{8}{x+2}

                       = \frac{8}{6+2}

                      = 1

<u><em>Final answer</em></u>:-

(f ο g)(-1) = 1

iris [78.8K]

Answer:

I think the answer is 2/5

Step-by-step explanation:

There are 10 ducks and there are 4 of them that are multiple of 3 (9, 18, 21, 27).

You end up with 4/10 but that is not an option.

If you reduce it you will end up with 2/5

PLEASE HELP (answer only if you now)
____ [38]

Answer:

y = 30

Step-by-step explanation:

If y varies directly with x, then you can make a ratio:

24/8

Simplify the ratio:

3/1

Y is always the first number/ on top in a ratio, that's where I get 24 over 8

3/1 means that y is triple x

so 10 * 3 is 30
