X = 8 is the solution for which equation? A. -4 + 8p = 68

B. 4 + 8p = 68

C. 4 + -8p = 68

D. 4 + 8p = -68

a. -4 + 8p = 68

         8p = 68 + 4 = 72

           p = 72/8 = 9

a. is not the answer as the solution is not 8

b. 4 + 8p = 68

        8p = 68 - 4 = 64

         p = 64/8 = 8

b. is the answer as the solution is 8

c. 4 + -8p = 68

         -8p = 68 - 4 = 64

            p = 64/-8 = -8

c. is not the answer as the solution is not 8

d. 4 + 8p = -68

        8p = -68 -4 = -72

          p = -72/8 = -9

d. is not the answer as the solution is not 8

b. is the answer

hope this answer helps you..

please mark as brainliest.. thank you!

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
