Answer:
How to Graph a Linear Inequality
First, graph the "equals" line, then shade in the correct area.
There are three steps:
1.) Rearrange the equation so "y" is on the left and everything else on the right.
2.) Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
4.) Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

Answer:
x=12
Step-by-step explanation:
you need the x alone so you substract 3 from both sides.
Then you have, -x= -12
You need the x positive so you change the sign for it but as it is an equation you need to do the same thing on the other side, making both sides positive.
x=12
15x - 5(3x-7) = 14
15x - 15x+ 35 = 14
35 = 14 ...NOT TRUE
answer
NO solution
you got it correct
Answer:
257.5 mph
332.5 mph
Step-by-step explanation:
The initial distance between the two planes is 960 miles, while the final distance (after t=1.5 h) is 75 miles, so the total distance covered by the two planes in 1.5h is
miles
Calling v1 and v2 the velocities of the two planes, we have the following equations:
(1) 
--> velocity of plane 1 exceeds velocity of plane 2 by 75 mph
(2) 
--> the total distance covered by the two planes is 885 miles (t=1.5 h is the time, and the products v1 t and v2 t represent the distance covered by each plane)
Substituting t=1.5 h, the second equation becomes:
By substituting (1) into this last equation, we find:
And substituting this back into eq.(1), we find
So, the speeds of the two planes are
257.5 mph
332.5 mph
