Answer:
no
Step-by-step explanation:
<em>If the rate is a constant, the relationship is proportional.</em> (The rate is the constant of porportionality.)
_____
For two or more points on the function curve, divide the dependent variable value by the independent one. If you get the same result in every case, the relationship is porportional.
___
<em>Note</em>
For some non-proportional relationships, it is possible to find points on the graph that will pass the above test. If you suspect the relationship is actually not one of proportionality, try more points. Check also to make sure that (0, 0) is on the curve.
Answer:
Option C) 195 characters per minute
Step-by-step explanation:
We are given the following in the question:
Jude types 1,170 characters in 6 minutes..
We have to find the typing rate in characters per minute.
Thus can be done in the following manner:
Typing rate =
Thus, Jude speed in characters per minute is
Option C) 195 characters per minute
Really ? ?
Price per inch has the units of "price/inch". See that ? It comes from dividing 'price' by 'inches'.
Price = $7.56
Inches = don't know;
... but we know it's 7 feet, and every foot has 12 inches in it
... so there are (7 x 12) = 84 inches of ribbon.
Price per inch = ($7.56) / (84 inches)
Prince per inch = (7.56/84) (dollars/inch)
Now, YOU go ahead and do the division to get the final answer.

Answer: x = 4</h3>
===============================================
Explanation:
Saying "Points A,B, and C are collinear" means the three points all fall on the same line. For the sake of simplicity, assume the line is horizontal.
Since B is between A and C, we know that the order of the points from left to right is A, B, C.
Through the segment addition postulate, we say,
AB+BC = AC
(x+3) + (x) = 11
x+3+x = 11
2x+3 = 11
2x = 11-3
2x = 8
x = 8/2
x = 4
------------------
Extra info:
Using x = 4, we see that
AB = x+3
AB = 4+3
AB = 7
Note how this adds to BC = x = 4, getting us,
AB+BC = 7+4 = 11
which is the length of segment AC. This confirms AB+BC = AC is true and confirms our answer.
