A. set the top equation as x=something. you can do this by transforming functions.
answer x=2y-8
Then you substitute 2y-8 for x in the bottom problem. 4(2y-8) - 8y= 10.
Solve for y. you will get a false equation. -32=10. Proved.

B. we know that the lines are parallel. if the line don't have a solution that means that they don't intersect. that means they must be parallel because parallel lines never intersect.

Which coordinate divides the directed line segment from −10 at J to 23 at K in the ratio of 2 to 1?

oksano4ka [1.4K]

Answer:

Step-by-step explanation:

The difference of the two coordinates is ...

23 -(-10) = 33

The desired coordinate is 2/3 of that length from J, so is ...

J + (2/3)·33 = J +22 = -10 +22 = 12

The desired coordinate is 12.
