First, open the parenthesis. You get
6x^2 - 24x -16x^2 - 9x + 1
Then simplify to
-10x^2 - 33x +1

Given: AOB is a right angle

Crazy boy [7]

The missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.

<h3>How to find vertically opposite angles?</h3>

We want to prove that m∠BOC = 90°.

We are given that m∠AOB is a right angle triangle. Thus;

m∠BOC must also be equal to 90°

Now, since m∠BOC and m∠AOB are right angles, then it means that we must equally say that m∠DOA and m∠BOC are vertical opposite angles and they are as such equal.

Thus, the missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.

Graph g(x) = |x + 3|.

elena55 [62]

The graph of g(x) is gotten by translating the function f(x) = |x| down by 3 units to get to function g(x)

<h3>How to graph the equation of the function?</h3>

The equation of the function is given as; g(x) = |x| - 3

The above function is an absolute value function.

The parent function of an absolute value function is; f(x) = |x|

This means that the function f(x) is translated to get to function g(x)

In this case, the function is f(x) is translated down by 3 units to get to function g(x)

So, the graph of g(x) is gotten by translating the function f(x) = |x| down by 3 units to get to function g(x)

See attachment for the graph of g(x)

konstantin123 [22]

<u><em>Hi there! :)</em></u>

<u><em>Answer:</em></u>

<u><em>*The answer must have a negative sign.*</em></u>

Step-by-step explanation:

<h2><u><em>Lesson: Zero and Negative Exponents</em></u></h2><h2>Zero exponent rule: $a^0=1$ </h2>

First, you multiply by exponents.

$2^4=2*2*2*2=16$

It change positive to negative sign.

<u><em>Final answer is B. -16</em></u>

Hope this helps!

Have a nice day! :)
