Find the solution for the equation and check it.
7+y=-2
Solution:
Check:

y=-9

7+(-9)=-2  ,  -2=-2

Step-by-step explanation:

You want to isolate y by itself so you have to subtract 7 from both sides. -2-7=-9 so y=-9. To check this equation, you have to plug 9 back into the equation. It will look like 7+(-9)=-2. -2=-2 so that means that y=-9.

If this helped, mark as brainliest

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."

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
