Angel dilates the photograph , rectangle ABCD , scale factor with 1/2 the center of dilation at the origin to form rectangle A^ prime B^ prime C^ prime D^ prime and then translates rectangle A^ prime B^ prime C^ prime D ' 3 units down to form rectangle A^ prime prime B^ prime prime C^ prime prime D^ prime What are the coordinates of vertex D ?

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

look at photo

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
