I need help I tried to do this question with one C and with two C
OverLord2011 [107]

There are two c's. You must pay attention to capitalization, there's a lowercase c and an uppercase C which represent two different variables. Also, the W is capitalized which could make your answer incorrect if you don't use the same notation.

Solving for small c..

C = \frac{Wtc}{1,000}   \\\\ 1,000C = Wtc \\\\\frac{1,000C}{Wt}= c

So it's the answer shown in the picture, but it  should be a capital W instead of a lowercase w.

(-1,-2) and (3, -162) a. Is there a line th(at goes through these two points? How do you know? If there is one, what is the equa
lana [24]

Answer:

The equation of line for given points is y = - 40 x - 42  

Step-by-step explanation:

Given two points as :

( -1 , - 2 )  and ( 3 , - 162 )

Now, Equation of line in points form

y - y_1 = m × ( x -  x_1 )

Where m is the slope of line

And, m = \frac{y_2 - y_1}{x_2 - x_1}

or, m = \frac{ - 162 + 2}{ 3 + 1}

or, m =  \frac{ - 160}{ 4}

∴   m = - 40

So, Slope of line for given points is - 40

Now equation of line can be written as

y - ( - 2 ) = ( - 40 ) × ( x -  ( - 1 ) )

or, y + 2 =  ( - 40 ) × ( x + 1 )

or, y + 2 = - 40 x - 40

or, y = - 40 x - 40 - 2

∴  y = - 40 x - 42        

Hence the equation of line for given points is y = - 40 x - 42    Answer

Find the value of this expression if x=9 x2 + 6 / x - 6
GREYUIT [131]

Answer:

87/3

Step-by-step explanation:

Here we are given the expression:

\frac{x^{2}+6}{x-6}

Now we have to find the value of this expression when x equals 9.

So plugging the value of x as -9 in the given expression:

\frac{x^{2}+6}{x-6}

=\frac{(9)^{2}+6}{9-6}

=87/3

So on evaluating we get the value of expression as 87/3.
