-x(3x-4)=28-3p(p+1)-x(3x-4)=28-3p(p +1)

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

the 3rd on is correct

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

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:
