Ms. Drummond told her class that some dilations make figures bigger, some make figures smaller, and some make figures the same size.
Select two of the scale factors that support Ms. Drummond's claim that some dilations
make figures smaller.

Its   0.75   and   -2/3

Step-by-step explanation:

Because, whenever they are a fraction, its means division, which means that, that would make the figure smaller. If you convert 0.75 as a fraction, the fraction would be, 3/4.

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
