Find the equation of the line that passes through the point of intersection of x + 2y = 9 and 4x -2y = -4 and the point of inter
Rudik [331]

Answer:

y=-6x+10

Step-by-step explanation:

The point of intersection of

x+2y=9...eqn1


and


4x-2y=-4...eqn2

is the solution of the two equations.


We add equation (1) and equation(2) to get,

x+4x+2y-2y=9+-4


\Rightarrow 5x=5


\Rightarrow x=1

We put x=1 into equation (1) to get,

1+2y=9

\Rightarrow 2y=9-1

\Rightarrow 2y=8

\Rightarrow y=4


Therefore the line passes through the point, (1,4).


The line also passes through the point of intersection of

3x-4y=14...eqn(3)

and

3x+7y=-8...eqn(4)

We subtract equation (3) from equation (4) to obtain,

3x-3x+7y--4y=-8-14


\Rightarrow 11y=-22

\Rightarrow y=-2


We substitute this value into equation (4) to get,

3x+7(-2)=-8


3x-14=-8


3x=-8+14


3x=6

x=2

The line also passes through

(2,-2)



The slope of the line is

slope=\frac{4--2}{1-2} =\frac{6}{-1}=-6


The equation of the line is

y+2=-6(x-2)

y+2=-6x+12


y=-6x+10 is the required equation

The area of a rectangle is 4y + 10.
galben [10]
By definition, the area of a rectangle is given by:
 A = (w) * (l)

 Where,
 w: width
 l: long
 We then have the following area:
 A = 4y + 10

 Factoring the area we have:
 A = 2 (2y + 5)

 Therefore, according to the definition, two possible dimensions of the rectangle are:
 w = 2

l = 2y + 5
 Answer:
 
The area of the rectangle in factored form is:
 
A = 2 (2y + 5)

 One possible set of dimensions for this rectangle is:
 
w = 2

l = 2y + 5
