Answer:

There is no slope

Step-by-step explanation:

The equation for finding the slope is:

y2 - y1

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

x2 - x1

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

-9 - (-9)

-----------                <-----------------         Here is your starting equation

7 -  (-9)

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

-9 + 9

---------

7 + 9

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

0

There is no slope because you can't divide 0 by 16

Hope that helps :)

n music, a quaver is one-eighth of a semibreve (whole note). What fraction of a semibreve is a hemidemisemiquaver? (Hint: hemi-,
Dmitry [639]

Answer:

\dfrac{1}{64}

Step-by-step explanation:

Hemi-, demi- and semi- are prefixes which mean <u>half</u>.

When applied to musical notation, each time a prefix is added it means the note's value is <u>halved</u>.

Therefore, if a quaver is one-eighth of a semibreve, then a <u>semiquaver</u> is half of a quaver, which means it's <u>one-sixteenth of a semibreve</u>.

\large \begin{aligned}\sf quaver & = \sf\dfrac{1}{8}\:of\:a\:semibreve\\\\\implies \sf hemisemidemiquaver & = \sf \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{2} \times quaver\\\\& = \sf \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{8}\\\\& = \sf \dfrac{1}{64}\:of\:a\:semibreve\end{aligned}

Therefore, a hemisemidemiquaver is one-sixty-fourth of a semibreve.

Please help
Firlakuza [10]

Answer:

Step-by-step explanation:

y = -2/3 x       multiply both sides the first equation by 6

6y = -4x                    Add 4x to both sides.

6y + 4x = 0

<u>-9y +4x = - 40   </u>        Subtract the bottom equation

15y =  - 40                 Divide by 15

y = -40/15

y = - 2.7

======================

6y = -4x

6*(-2.67) = -4x

-16 = - 4x

x = - 16/-4

x = 4
