PLEASE HELP ASAP. the coordinates of the pre-image triangle DEF are D (-4,5.), E ( 9,-2.), F (0,-6.). the coordinates of the image triangle D'E'F' are D' (-8,10.), E' (18,-4.), F' (0,-12.). what is the scale factor from the pre-image to the image of the center of the dilation is (0,0.)?
a. 1/2.
b. 2.
c. 3.
d. 1/3.

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
