Amachine has an efficiency of 70%. how much work does the machine do when 20,000 j of work is done on it? a. 14,000 j b. 28,600 j c. 1,400,000 j d. 2,860,000 j

A. 14,000

I just took the test so I am positive this is right : )

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.
