Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

Answer:

x = 9 , y =3

Step-by-step explanation:

-3x + y = 0 ---- 1

2x -2y = -12 -----2

By elimination method:

let's first eliminate x

we can do that by making x equal in both equations

multiply equation 1 by 2 ( because 2 is the coefficient of x in equation 2 and remember we want to equate both equations)

multiply equation 2 by -3 ( because -3 is the coefficient of x in equation 2 and remember we want to equate them both)

-3x + y = 0 ×2

2x -2y = -12 ×-3

-6x + 2y = 0 ----3

-6x + 6y = 36 -----4

subtract equation 4 from 3

that will give

0-4y = -36

which is

-4y = -36

divide both sides by coefficient of y which is-4

(-4y) ÷ (-4) = (-36)÷(-4)

answer : y= 9

substitute 9 for y in equation 1

-3x + y = 0

-3x + 9 = 0

subtract 9 from both sides

-3x +9-9= 0-9

-3x = -9

divide both sides by coefficient of x which is-3

(-3x)÷(-3) = (-9÷-3)

x = 3

a dvd has a diameter of 16 centimeters.what is the the area of the dvd?round the answer to the nearest hundredth.use 3.14 for n
melomori [17]

Answer:

A = 201 cm²

Step-by-step explanation:

We know that the area of a circle can be calculated with the formula:

A = πr² = π(d/2)²

with d being the diameter.

Therefore:

A = 3.14(8cm)² = 201 cm²

PLEASE HELP ASAP Hi! Please help me guys!!! This is difficult for me.. :c ~Why might a solution to an inequality not be reasonab
abruzzese [7]

Answer:

When the solution is negative

Step-by-step explanation:

One example, let's say you are buying pens and each pen cost 3 dollars and you cannot spend more than 15 dollars, how many pens can you buy?

The inequality would be 3x < 15, so any negative solution is not reasonable because you cannot buy negative pens. The same goes for most real-world problems dealing with time, money, or distance.
