Classify these numbers as rational or irrational

-4/5, 2.5, 0.4, √16 are rational and √2 is irrational.

Step-by-step explanation:

-4/5 is a rational number.

Reason: It is in the fraction form with -4 in the numerator and 5 in the denominator.  .

√2 is irrational.

Reason: since it cannot be written as a fraction.

2.5 is rational number.

Reason: It can be written in the form of fraction such as 5/2.

√16 is rational.

Reason: It can be simplified as +4 or -4 which are integers.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

if i put something wrong your not gonna like it so rather not say nothing.
