Answer:

y-1=\frac{1}{8}\left(x-7\right) is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Step-by-step explanation:

The endpoints:

  • B(6,9)
  • C(8,−7)

Calculating the Midpoint M of BC:

\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)

\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)

The Midpoint M of BC =\left(\frac{8+6}{2},\:\frac{-7+9}{2}\right)

                                     =\left(7,\:1\right)

Calculating the slope of BC:

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)

m=\frac{-7-9}{8-6}

m=-8

Given a line with slope m then the slope of a

line  perpendicular to it is:

m_{prependicular}=-\frac{1}{m}=-\frac{1}{-8}=\frac{1}{8}

Equation of line using point-slope form

y-y_1=m\left(x-x_1\right)

y-1=\frac{1}{8}\left(x-7\right)        

     

Therefore, y-1=\frac{1}{8}\left(x-7\right) is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Write the numerical expression. 6 times the sum of 12 and 8. Write your answer with no spaces.
Murljashka [212]

Answer:

6(12+8)

Step-by-step explanation:

the word 'times' would indicate the multiplication of 2 numbers

the word 'sum' would indicate the addition of 2 numbers. in this case, 12 + 8 would be placed in parenthesis

hope this helps!! :)

Rewrite, differentiate and simplify:<br> 3/(2x)^3
Llana [10]

\frac{dy}{dx} = - \frac{9}{8x^{4} }

let y = \frac{3}{(2x)^{3} } = \frac{3}{8} x^{-3}

differentiate using the power rule

\frac{d}{dx} (ax^{n} ) = nax^{n-1}

\frac{dy}{dx} = - \frac{9}{8}x^{-4} = - \frac{9}{8x^{4} }

Question: A box of chocolates contains square chocolates, which weigh 10 g each, and round chocolates, which weigh 8 g each. The
Viktor [21]

Answer: the box contained 9 square chocolates and 15 round chocolates.

Step-by-step explanation:

Let x represent the number of square chocolates contained in the box.

Let y represent the number of round chocolates contained in the box.

The box of chocolates contains square chocolates, which weigh 10g each and round chocolates which weigh 8g each. The combined weight of all the chocolates is 210g. It means that

10x + 8y = 210- - - - - - - - - - -1

The number of round chocolates is 3 less than twice the number of square chocolates. It means that

y = 2x - 3

Substituting y = 2x - 3 into equation 1, it becomes

10x + 8(2x - 3) = 210

10x + 16x - 24 = 210

26x = 210 + 24

26x = 234

x = 234/26

x = 9

y = 2x - 3 = 2 × 9 - 3

y = 18 - 3

y = 15
