Write an expression that represents the total owed for 6 months of cable at a price of c dollars for each month, plus a one-time

matrenka [14]

Answer is 6(c) + 50

Step by step

We know the following

6 months cable multiplied by “c” dollars per month plus $50 one time fee
6 (c) + $50

We multiply 6 months times the unknown “c” per month. Then we add the one time fee.

The other three options multiply $50 by 6 months, by 2 and by “c”, therefore not correct.

Write a linear equation in Slope-Intercept Form for a line that goes through the

Kitty [74]

Answer:

y = -2x -9

Step-by-step explanation:

<h2><u>in order to solve this question you have to do the following : </u></h2>

1. find the midpoint of the coordinates given

2. find the gradient of the line

3. make the equation

<h3><em><u>STEP : The midpoint </u></em></h3>

formula of the midpoint is

$\frac{x2 + x1}{2} , \frac{y2 + y1}{2}$

now place the values in the equation :

$\frac{-4 +-2}{2} , \frac{-5 + -1 }{2}$

midpoint = ( -3 , -3)

<h3><em><u>STEP 2 : The gradient </u></em></h3>

formula of finding the gradient

$\frac{y2-y1}{x2-x1}$

insert the values in the equation:

$\frac{-5-(-1)}{-2-(-4)}$

= $\frac{-4}{2} = -2$

gradient = -2

<h3><em><u>STEP 3: Form the equation </u></em></h3>

use the formula of the equation :

$(Y - y1) = m( X - x1)$

now make use of the gradient(m) and the midpoints and insert into the equation

(y-(-3)) = -2(x -(-3))

hence

y+3 = -2 (x +3)

y= -2x -6 -3

<h3><u /></h3><h3><u>y = -2x -9 </u></h3>
