Step-by-step explanation:

all u gotta do is divide 6.4 by 4:)

hope that helps!<3

anser is a

step-by-step explanation:

negitive slope

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.
