The equation 14m = 400.40 can be used to find the cost per yard m, in dollars, of mulch. what is the value of m?

he is right. but if you put the answer make sure it has the tenths place its 28.60  if you put 28.6 it will say its incorrect.

b.an increase in a causes b to decrease

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.
