First, let's see what group of numbers each one is:

The real numbers are all numbers including irrationals, decimals, etc.

Integers are numbers that don't have any fractional parts, which means that decimal numbers are not integers.


So, since we work with the number 0,5 and 2,5 (height of the fifth step) I think the answer is A, integers, because you can't go up or down less than one step. You can either go one step, or more. It's impossible to walk 1/2 step.


Hope it helped,

The domain is the set of integers since the number of steps can be positive and negative without a partial step (either you take the step or not).

Answer:

x and y can have many values

Step-by-step explanation:

-24x - 12y = -16

Then: 24x + 12y = 16

We know: 6x + 3y = 4

X and Y can have a lot of valoues.

6x + 3y = 4

3 ( 2x + y) = 4

2x + y= 4/3

2x+y= 1.333...

Compound interest:

A=P\left(1+\dfrac rn\right)^{nt}

where P is the amount you start with, r is the interest rate, n is the number of times interest is compounded per year, and t is amount of time that passes.

4272\left(1+\dfrac{0.12}1\right)^{1\times3}=4272\times1.12^3\approx6001.85
