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.

For which value of x is the equation 3(x+2)+x=2x+16 true?
Arturiano [62]

Answer:

1) take the first part of the equation and work it by multiplying (x+2) by 3

3(x+2)+x

3x +6+x

2)put the answer you got into the question you were given

3x + 6+x =2x +16

3)group the x variables and the non x variables

3x +x -2x =16 -6

4) Now work the equation you have

3x+x-2x=16-6

4x-2x=16-6

2x=16-6

2x=10

5) you divide both sides by the x variable

2x=10

2x/2 =10/2

x=5

therefore x is 5

Movies are on sale for 3/4 the original price. If the original price is $16, what is the sale price?
Nesterboy [21]

If the original price is 16, then 3/4 of 16 is 12.

$12


Dividing 16 by 4 (the denominator), you get 4. Then 4 x 3 (the numerator) is 12.
