Answer:

0

Step-by-step explanation:

\frac{1}{2^3}\left(-32+8\right)-\frac{\left(-3\right)^3}{9}

\frac{1}{2^3}\left(-32+8\right)=-3

-3-\frac{\left(-3\right)^3}{9}

\frac{\left(-3\right)^3}{9}=-3

-3-\left(-3\right)

* -\left(-a\right)=a

Solve the system of linear equations by elimination.<br><br> −2x−5y=9 <br> 3x+11y=4
SIZIF [17.4K]

Answer:

x=-17, y=5. (-17, 5).

Step-by-step -2x-5y=9

3x+11y=4

---------------

3(-2x-5y)=3(9)

2(3x+11y)=2(4)

---------------------

-6x-15y=27

6x+22y=8

-----------------

7y=35

y=35/7

y=5

3x+11(5)=4

3x+55=4

3x=4-55

3x=-51

x=-51/3

x=-17

A theorem in geometry states that the measure of an inscribed angle is half the measure of its
RoseWind [281]

Answer:

The first option is the correct option

Step-by-step explanation:

From the question  the slope  AC is evaluated as

            m_1 =  \frac{b-0}{a- (-c)}

            m_1 =  \frac{b}{a+c}

And  the slope of line  CB is mathematically evaluated as

        m_2 =  \frac{0-b}{c-a}

        m_2 =  \frac{b}{c-a}

Now for lines that are perpendicular to each other then the product of their slope should be equal to  -1

So if  m ZC = 90^o

Then

     m_ *m_2 = -1

i,e  

      [\frac{b}{a+ c} ] [\frac{b}{a-c} ] = -1
