The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis.
Answer:
D = 
Step-by-step explanation:
given R =
multiply all terms on both sides to eliminate the fraction
3R = 3D - T ( add T to both sides )
3R + T = 3D ( divide both sides by 3 )
D = 
Answer:

Step-by-step explanation:
x2+5x+
4/x+4
Answer:
-1/13
Step-by-step explanation:
5-x= 12x + 4
5-4=12x + x
1 = 13x
-1/13 = x
