solve the system of equations below by graphing both equations with a pencil and paper, what is the solution? y= -x-1 y=x+3

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

150.6

all i did was i multiplied 5.02 by 30

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:
