Please hurry and I will give you brainlest if your show your work Dave has outgrown the bike he rode when he was small. So, for his twelfth birthday, his parents surprise him with a five-speed Blaze Rider 2000! Dave has never had a bike with multiple speeds before, and he is eager to learn how it works. He starts by testing the middle speed. There is a proportional relationship between the number of times Dave pedals, x, and the number of times the wheels rotate, y. What is the constant of proportionality? Write your answer as a whole number or decimal. wheel rotations per time Dave pedals

The constant of proportionality is 2.

Step-by-step explanation:

All the y values are twice as much as the corresponding x values

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: apothems is your answer

step-by-step explanation: hope u get it right
