Answer:
-1/2
Step-by-step explanation:
-2(4x - 3) = 10
First distribute the -2 to 4x and -3; it turns into
-8x + 6 = 10
The subtract 6 on both sides which equals
-8x = 4
Then divide -8 on both sides...
x = -4/8 or -1/2
Answer:
Distance=13.60
Step-by-step explanation:
The Distance between the two points in coordinate system is find by using the distance formula.
If two points
and
are given:

For the points:


The distance between the points is 13.60
In order to solve this equation you must eliminate one of the variables.
By multiplying by -3 you eliminate the y variable, making A the correct answer.
-6x-3y=-66
5x+3y=29
-x=-37
x=37
