If you are looking to find the value of x then you have to use distributive property.

1st: multiply -3 by 2x and 4 -3(2x+4)

-6x -12

2nd: do the same thing on the other side which is multiply 3 by x and -6

3(x-6)

3x-18

3rd: Then you have -6x-12=3x-18

+12 +12

add 12 to each side so then you have -6x=3x-6

then divide by -6 on each side and the answer is x= 2/3

Three vertices of a rectangle are given. Find the coordinates of the fourth vertex.

kykrilka [37]

The distance between (2,5) and (6,1) is:

$\sf Distance = \sqrt{\left( 6 - 2 \right)^2 + \left( 1 - 5 \right)^2} \\\\ =\sqrt{ 16 + 16} \\ \\ = \boxed{\bf{4 \sqrt{ 2 } }}$

The distance between the fourth vertex and (4,-1) should also be 4√2

The only point that gives us that distance is B. (0,3)

$\sf Distance = \sqrt{\left( 4 - 0 \right)^2 + \left( -1 - 3 \right)^2} \\ \\= \sqrt{ 16 + 16} \\ \\ = \boxed{\bf{4 \sqrt{ 2 } }}$

Your final answer is B. (0,3)

-4x + y = -9 - 5x + 2y = 3 : Solve the Linear equation

Yuri [45]

-4x+y= -9 can be turned into
y= -9 + 4x

5x+2y=3 (plug y in)
5x+2(-9+4x)=3
5x-18+8x=3
5x+8x=3+18
13x=21
divide 13 on both sides
x=1.6
