b. The set of all positive real numbers
c. The set of all Integers
d. The set of all positive integers

Explain how you know.

Which is the correct description of function A?
a. Linear and decreasing
b. Linear and increasing
c. Nonlinear and decreasing
d. Nonlinear and increasing

Explain how you know.

B, because the height of the boys can be anywhere between any positive number, however not negative because you can't be a negative height.

D, its is non-linear because their heights won't be going up by the same amount each time your x-value increases because the human body grows at different rates, it will be increasing because the human body is always growing until death.

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
