There are 3 times as many students participating in the hiking trip this year than last year. There are 42 students on the trip last year. Explain how to find the number of students that came on the hiking trip last year.

42x3=126

Step-by-step explanation:

Divide 126 in 3

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

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.
