Part I

\bf \begin{array}{l|lllllll}
x&2&\boxed{4}&6&8&\boxed{10}&12&14\\\\
y&1&\boxed{6}&11&16&\boxed{21}&26&31

&({{ 4}}\quad ,&{{ 6}})\quad 
%   (c,d)
&({{ 10}}\quad ,&{{ 21}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{21-6}{10-4}


part II

\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad 
\begin{array}{llll}
\textit{plug in the values for }

y_1=6\\
x_1=4\\
m=\boxed{?}
\end{cases}\\
\end{array}\\
\left. \qquad   \right. \uparrow\\
\textit{point-slope form}


now, the form above is the point-slope form, and that'd be the equation, you can leave it like so, or you can solve for "y", and put it in slope-intercept, same equation though.

Solve the equation for the red variable(C)in R-C=P
BARSIC [14]

If you want to solve the equation

R-C=P

for C, you can work like this: subtract P from both sides:

R-C-P = 0

Add C to both sides:

R-P=C

lord [1]

Answer:

2000 USD

Step-by-step explanation:

a. Difference for employee 1: 14000 - 10000 = 4000

b. Difference for employee 2: 11000 - 12000 = -1000

c. Difference for employee 3: 13000 - 11000 = 2000

d. Difference for employee 4: 10000 - 8000 = 2000

e. Difference for employee 5: 12000 - 9000 = 3000

The absolute mean difference of 5 employees is

(4000 - 1000 + 2000 + 2000 + 3000)/5 = 10000/5 = 2000

So the average net increase of each employed in the past month is 2000 USD

Help please...........<br><br><br>1. y = 3 x<br> y = -8x<br><br><br>2. y = - 7x<br> y =-4x - 12
geniusboy [140]
1. -8x = 3x

-11x = 0

x= 0

y= 3(0)= 0

(0, 0)

2. -7x = -4x - 12

-3x = -12

x = 4

y = -7(4)= -28

(4, -28)
