Answer:
In mathematics, a function on the real numbers is called a step function (or staircase function) if it can be written as a finite linear combination of indicator functions of intervals. Informally speaking, a step function is a piecewise constant function having only finitely many pieces.

Answer:
65 cats
Step-by-step explanation:
cats: dogs: total
5: 3: 5+3=8
We need 8 to be 104
104/8 = 13
Multiply each by 13
cats: dogs: total
5*13: 3*13: 8*13
65 39 104
There are 65 cats and 39 dogs
Answer:
There are 14 pairs of Brand A sold.
Step-by-step explanation:
In order to find this, you need to set up a system of equations. You can set up on equation for the number sold:
A + B = 32
And you can set up one for the amount made:
30A + 35B = 1090
Now, in order to solve for the amount of A sold, multiply the first equation by -35 and add the two equations together.
-35A - 35B = -1120
30A + 35B = 1050
----------------------------
-5A = -70
A = 14
