(My Math Problem) Use properties of operations to determine whether the expressions are equivalent.

2k + 5 + 2k and 5 + 4k

The expressions are not a equivalent or they are equivalent?

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

0.32

step-by-step explanation:

2.24/7

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
