Answer:
The result for this equation is
.
Step-by-step explanation:
-Solve the equation:

-Use Distributive Property:


-Subtract 6x and from 12x :


-Add both sides by 30:


-Then, you divide both sides by 6:


So, therefore the answer is
.
Answer:
How much time do i have?
Step-by-step explanation:
Answer:
z ≥ -8 - (-5)
Step-by-step explanation:
Answer:
The line u and line v have no point of intersection because they are parallel lines
Step-by-step explanation:
The slope of a straight line is given as follows;

The slope of line u is (4 - (-8))/(5 - 9) = -3
The equation for line u is y - 4 = -3*(x - 5)
y = -3·x + 15 + 4 = 19 - 3·x
The slope for line v is (-7 - 2)/(7 - 4) = -3
The equation for the line v is y - 2 = -3*(x - 4)
∴ y = -3x + 12 + 2 = -3x + 14
y = 14 - 3·x
Therefore. line u and line v have the same slope and are therefore parallel and they do not intersect
U subtract 4x by 5x and then you add 3 by -21 and the answer is x=18
