84/7= $12 per garage
12(9)= $108
She would make $108
X + 1 = - 1/4 - 5/8
x + 1 = -2 - 5 / 8
x + 1 = - 7/ 8
x = -7 /8 - 1
x = - 7 - 8 / 8
x = - 15 / 8
First join the log4 on the left:
log4( x*(x-3) = log4(-7x+21)
Then x = -7, works: -7*(-10)=70 = -7*(-7)+21
x=-3, 18 = 42, does not work
x=3 0=0 works,
However, when one puts x = -7 in the *original* exression, log4(-7) or log4(-10) do not exist (you know why?). So x= -7 is extraneous.
Now x=3 gives log4(0) on the left and right, which does not exist.
So, C is the answer, both are extraneous. Seem to work but indeed don't work in the *original* equation
Answer:
frequency
Step-by-step explanation:
Planck showed that the energy that is emitted or absorbed by an object is proportional to the _<u> </u><u>frequency</u><u>__</u>__ of the radiation.
