This is not a function. There are multiple outputs for the same input at $x=2$ . A function only has 1 output for every input.

Answer:

$(x+5)^2=4$

Step-by-step explanation:

We have:

$x^2+10x+21=0$

First, subtract 21 from both sides:

$x^2+10x=-21$

Now, we can complete the square. We will divide the coefficient of the b term and square it. So:

$(\frac{b}{2})^2\Rightarrow(\frac{10}{2})^2=(5)^2=25$

So, we will add 25 to both sides:

$(x^2+10+25)=-21+25$

The left is the perfect square trinomial pattern. Add on the right:

$((x)^2+2(5)(x)+(5)^2)=4$

Final step:

$(x+5)^2=4$

Given the definitions of f(x) and g(x) below, find the value of (g o f)(0).

Mamont248 [21]

Answer:

its 3

so its

(4x+4)^2-2(4x+4)-5

so first you have to do

(4x+4)(4x+4)

the answer is 16x^2+32x+16

and then you do -2(4x+4) and then you add them so then its

16x^2+32x+16-8x-8-5

and then you just add like terms so its

16x^2+24x+3

and then you insert 0 for x

so the answer is 3

Answer:

There is money left over. They have 48.98 dollars left.

Step-by-step explanation:

Men costumes in total cost $102.68 and women costumes in total cost $248.34. There budget it $400 so we add both the men and women costumes together which is $351.02 which means that they do have left over money. To find the left over money, we have to subtract $400 from $351.02 which is equal to $48.98.
