Use transformations to solve the equation. 2 1/2 = -3/4m

m= -10/3

Step-by-step explanation:

Transformation means to move the same items on one side and find m.

so 2 1/2 = -3/4 m

5/2 = -3/4 m

m= 5/2 * -4/3

m= -10/3

a: 1/6, j: 1/4

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
