B. 39
C. 35
O D. 43

(-5,-28)

i graphed to on desmos.

1010: 3030

is it i think

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
