If elephant grass grows 2 2/5 inches a day, how many inches will it grow in 7 days?

16  4/5  inches

Step-by-step explanation:

We can find the amount it will grow by taking the rate it grows times the time

growth = rate* time

            = 2 2/5 * 7

    Changing the mixed number to an improper fraction

2 2/5 = (5*2+2)/5 = 12/5

growth = (12/5)*7

             =84/5  inches

Changing this back to a mixed number

5 goes into 84  16 times  (5*16 = 80  )  with 4 left over

16  4/5  inches

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
