Answer:

x=70 degree

Step-by-step explanation:

x+110 =180 degree (the relation between x and 110 degree is that they are co exterior angles are same side exterior angles and sum of co exterior angles is always 180 degree)

x=180-110

x=70 degree

What is the scale factor (k) of the dilation if C is (-6,9) and C' is (-2,3)?
bekas [8.4K]

Answer:

Step-by-step explanation:

Given the original coordinate as C (-6, 9) and new coordinates after dilation as C' (-2, 3), we can see that the value of the new coordinates has reduces by a factor. Let the factor be k

For the x coordinates:

C' = kC

x' = kx

-2 = k(-6)

-2 = -6k

Divide both sides by -6

k = -2/-6

k = 1/3

For the y-coordinates:

y' = ky

3 = 9k

Divide both sides by 9:

3/9 = 9k/9

1/3 = k

k = 1/3

Hence the scale factor of the dilation is 1/3

The relationship between temperature in degrees Fahrenheit and degrees Celsius is shown in the graph above
pentagon [3]
It is a little difficult to see the graph but I am assuming that the x-axis is temperature in Celsius and the y-axis is temperature in Fahrenheit. 

Since the y-intercept is always the point at which the x-value is equal to 0, in this case the y-intercept would be the Fahrenheit temperature that is equivalent to 0°C.

I hope this helps.

trapecia [35]

Given:

Kate wants to buy some daisies for $6.99, some potting soil for $3.98, and a ceramic pot for $7.95. She has $20.00

Required:

Amount of change Kate receives back?

Explanation:

We will add each expense

6.99+3.98+7.95=18.92

Now, amount of change Kate receives back is 20.00 - 18.92 = 1.08

Answer:

Hence, amount of change Kate receives back is 1.08

Find the multiplicative inverse of

\mathsf{z=6+2i}

________


The inverse multiplicative of  \mathsf{z=a+bi}  is

\mathsf{\dfrac{1}{z}}\\\\\\
=\mathsf{\dfrac{1}{a+bi}\qquad\quad(a\ne 0~~and~~b\ne 0)}\\\\\\
=\mathsf{\dfrac{1}{a+bi}\cdot \dfrac{a-bi}{a-bi}}\\\\\\
=\mathsf{\dfrac{1\cdot (a-bi)}{(a+bi)\cdot (a-bi)}}\\\\\\
=\mathsf{\dfrac{a-bi}{a^2-\,\diagup\hspace{-10}abi+\,\diagup\hspace{-10}abi-(bi)^2}}

=\mathsf{\dfrac{a-bi}{a^2-b^2\cdot i^2}}\\\\\\
=\mathsf{\dfrac{a-bi}{a^2-b^2\cdot (-1)}}\\\\\\
=\mathsf{\dfrac{a-bi}{a^2+b^2}}\\\\\\\\
\therefore~~\mathsf{\dfrac{1}{a+bi}=\dfrac{a}{a^2+b^2}-\dfrac{b}{a^2+b^2}\,i\qquad\quad\checkmark}

________


For this question,

\mathsf{z=6+2i}


So,

\mathsf{\dfrac{1}{z}}\\\\\\
=\mathsf{\dfrac{1}{6+2i}}\\\\\\
=\mathsf{\dfrac{6}{6^2+2^2}-\dfrac{2}{6^2+2^2}\,i}\\\\\\
=\mathsf{\dfrac{6}{36+4}-\dfrac{2}{36+4}\,i}\\\\\\
=\mathsf{\dfrac{6}{40}-\dfrac{2}{40}\,i}


\therefore~~\mathsf{\dfrac{1}{z}=\dfrac{3}{20}-\dfrac{1}{20}\,i}\quad\longleftarrow\quad\textsf{this is the answer.}


I hope this helps. =)

bazaltina [42]

Answer:

7

Step-by-step explanation:

First, we solve for j in the first equation:

4j+3=-5

4j=-8

j=-2

Now we plug j into j+9:

-2+9=7

So j+9 is 7
