Answer:

(4,1)

3 x + 3 y = 15 - (-2 x + 3 y = -5)

3x + 3y = 15

2x - 3y = 5      +

____________

5x         = 20

x = 4

(3*4) + 3y = 15

12 + 3y = 15

3y = 15 -12

3y = 3

y = 1

4. Why do people sometimes use credit to pay for items instead of just using cash?
Makovka662 [10]

Answer:

Some people use credit to pay for items instead of just using cash so they do not have to carry money around and so it is easier. ... It is preferable to receive a low interest rate so you do not have to pay high amounts. Sometimes, lenders allow or require a down payment before they extend you the loan.

What is the equation for a line that passes through the points (5,-4) and (-10,17
maria [59]

Answer:

The equation of the line is 7 x +5 y = 15.

Step-by-step explanation:

Here the given points are ( 5, -4) & ( -10, 17) -

Equation of a line whose points are given such that

( x_{1},y_{1} ) & ( x_{2}, y_{2}  )-

 y - y_{1}   = \frac{y_{2} - y_{1}  }{x_{2} - x_{1}}  ( x - x_{1}  )

i.e.  <em>y - (-4)= \frac{17 - (-4)}{-10 - 5}  ( x- 5)</em>

<em>      y + 4 = \frac{17 + 4}{ -15} ( x - 5)</em>

<em>      y + 4 = \frac{21}{-15}  ( x - 5 )</em>

<em>      ( y + 4)  =  \frac{7}{- 5} ( x - 5)</em>

<em>      5 (y + 4 ) = - 7 (x - 5 )</em>

<em>      5 y + 20 = -7 x + 35</em>

<em>      7 x + 5 y = 15</em>

Hence the equation of the required line whose passes trough the points ( 5, -4) & ( -10, 17)  is 7 x + 5 y = 15.
