<span>1. First, label the axis on your graph, with units:
time on the x-axis, in units of hours;
distance on the y-axis, in units of miles.
2. Draw a graph of distance vs. time. Distance after the first hour = 69 miles, distance after the 2nd hour = 138 miles, etc.
3. Observe that this graph is a STRAIGHT LINE with constant slope. Therefore the relationship is PROPORTIONAL.
For every other kind of graph -- i.e. not a straight line -- the relationship is NON-PROPORTIONAL.

Answer:
C.
Step-by-step explanation:
To find out if it is a factor divide 96 by 8 and you will see. Hope this helped you!!
We have
x² + 24x = 17 (1)
Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.
Therefore
x² + 24x = (x+12)² - 144 (2)
Substitute (2) into (1).
(x + 12)² - 144 = 17
(x + 12)² = 17 +144
(x + 12)² = 161
Answer:
We added 144 to the left side of equation (1) in order to make it a perfect square.
I can't tell u which equations have the same solution because there is no other equations listed. However, I can tell u the solution.
3/5x + 2/3 + x = 1/2 - 1/5x..multiply by common denominator of 30 to get rid of fractions.
18x + 20 + 30x = 15 - 6x
48x + 6x = 15 - 20
54x = -5
x = -5/54
