Answer:
Choice A
Step-by-step explanation:
When you have two shapes that are similar their sides are always proportional. So all we have to do is set up a proportion.

Now we cross multiply and solve

And that's it x equals 6 feet.
So basically the hypotenuse is the part of the triangle that connects the two sides that create the right angle
Answer:
Option D.
Step-by-step explanation:
The given points are (-2,0), (0,1), (0,-4) and (3,0).
In each ordered pair first element is x-coordinate and second is y-coordinate.
For 4 points, the table must have 2 columns and 4 rows.
So, the required table of values is
x y
-2 0
0 -4
0 1
3 0
Therefore, the correct option is D.
The cost depend on the number pencils, so the cost is the y and # of pencils is the x
Same as for question 7
To graph, the length depend on the time, so length is y, time is x
6. Linear
7. Not
