Will someone me with this because i don't understand and i don't want to fail my class.

4y + 1 = 4 - 5y

First option

Step-by-step explanation:

x - 4y - 1 =0; add both sides by + 4y + 1

x - 4y - 1 + 4y + 1 = 0 +  4y + 1

Simplifying

x = 4y + 1

x + 5y - 4 = 0; Add (-5y + 4) to both sides

x + 5y - 4 -5y + 4 = 0 -5y + 4

Simplying

x = -5y +4

x = 4 - 5y

Now you have both equations

x = 4y + 1

x= 4 - 5y

Now you can use the comparison method

4y + 1 = 4 - 5y

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
