Exponential growth is the function

Exponential decay is the function

So, the basic difference is that in growth the base is more than 1, and in decay the base is more than 0 but less than 1.
35.1 is the answer to this question
Team Tool Bella's average rate was 3 miles per hour.
X = 56 degrees because the sum of all the angles in a triangle is 180 degrees.
The expression for the cost of the ABC Book Club is 2<em>x </em>+ 40. The expression for the cost of the Easy Book Club is 3<em>x</em> + 35. To find when the total charge for both book clubs is equal, the two expressions must equal each other. (<em>x </em>= the number of books read)
2<em>x </em>+ 40 = 3<em>x</em> + 35
Subtract 35 from both sides.
2<em>x </em>+ 5 = 3x
Subtract 2<em>x </em>from both sides.
5 = <em>x</em>
So, the total charge for each club is equal when 5 books are read.
