Answer:
I think it's dilated by a scale factor of 5. Because the black one is 3 squares long and the purple one is 15. So divide those and you get 5! and to check just multiply 5x3 to find the length of the purple one!

Answer:
<u>3</u>
Step-by-step explanation:
Rearrange in the slope-intercept form :
Comparing this to the standard equation :
- m = slope
- c = y-intercept
- On comparing, it is clear that the slope of the line is <u>3</u>
When we divide the number of feet (~700) by the number of seconds (~20), we get a number that is more than 30 (ft/s). Thus, only choices B and D are viable.
When we invert that rate, we get 1/(30 ft/s) = (1/30) s/ft, leaving the only viable choice as ...
B. 32.6 ft/s and approximately 0.03 s/ft
______
Units (feet, seconds) multiply and divide like any other variable. It is often useful to keep the units with the numbers of a problem so you can tell if you've done the math properly. It is more likely to be correct if the units are correct.
