Which of the following is the solution to |x-1|=8

-7,9

Step-by-step explanation:

x-1=-8

x=-7

x-1=8

x=9

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

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
