Determine whether the situation involves permutations or combinations. Then solve. How many ways are there to place an algebra book, a geometry book, a chemistry book, an English book, and a health book on a shelf?

Step-by-step explanation:

Given that

Algebra book=1  

Geometry book=1

Chemistry book= 1

English book= 1

Health book= 1

Total number of books N = (1+1+1+1+1)= 5

      Permutation is used to  determines the number of possible arrangements in a set when the order of the arrangements is crucial.

Number of arrangements = N!

Number of arrangements= 5*4*3*2*1=  120

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

only 10/60 isn't equivalent

hope this : )
