X= a number
29 - 2x= 21
subtract 29 from both sides
-2x= -8
divide both sides by -2
x= 4
CHECK:
29 - 2x= 21
29 - 2(4)= 21
29 - 8= 21
21= 21
ANSWER: The number is 4.
Hope this helps! :)

Answer: 1</h3>
========================================================
Explanation:
Pick any two points you want from the blue line. I'll pick (0,1) and (1,2)
Apply the slope formula to those points
m = (y2-y1)/(x2-x1)
m = (2-1)/(1-0)
m = 1/1
m = 1
The slope is 1.
Notice how if we're at (0,1), then we move up 1 and over to the right 1 to arrive at (1,2).
slope = rise/run = 1/1
rise = 1, run = 1
Answer:
<u><em>D:</em></u> Each point (or pair) in a proportional relationship must share the same difference.
Answer:
The acceleration of the particle at any time t

Step-by-step explanation:
Given:
The position of a particle moving in a straight line at any time t is.

The velocity of the particle 



So the velocity of the particle 
The acceleration of the particle 


In this condition the acceleration does not depending upon the time, so the acceleration is constant
Therefore the acceleration of the particle at any time t
