modeling with mathematics the linear function m=55-8.5b represents the amount m (in dollars) of money that you have after buying b books.

1. find the domain of the function.
a.)0, 1, 2, 3, 4, 5, 6$

.5,-2.5,-3.5,-4.5,-6.5,-7.5,-8.5

c.)all real numbers greater than $0$

d.)all whole numbers less than $100$

2.
is the domain discrete or continuous? explain.

the domain is because the amount of must be a number.

discrete or continuous books or money decimal or whole number

2/5

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
