The number of bacteria in a petri dish is multiplied by a factor of 1.2 every hour. there were initially 500
bacteria.
which expression gives the number of bacteria after 3 hours?

(1.2×3)500

Step-by-step explanation:

the 1.2 factor will be multiplied by the hours given then times that by the starting amount of bacteria.

its 500.1.2.1.2.1.2

Step-by-step explanation: I got it

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

if you was gonna solve for a, a is a   < -12
