Answer:

Domain: {-2, 0, 1, 3}

General Formulas and Concepts:

<u>Algebra I</u>

  • Domain is the set of x-values that can be inputted into function f(x)

Step-by-step explanation:

We are given a set of coordinates:

{(-2, 4), (1, 3), (0, -4), (3, 2)}

We can separate the <em>x</em> and <em>y</em> values:

x: {-2, 1, ,0, 3}

y: {4, 3, -4, 2}

We know that domain is all x-values. Rearrange into number line form:

x: {-2, 0, 1, 3}

Please help me with this question step by step. A rectangle has a width of 2x exponent 2 +4x+1) and a length of (8-x). What is t
timurjin [86]

Answer:

A = (2x² + 4x + 1) (8 − x)

A = -2x³ + 12x² + 31x + 8

Step-by-step explanation:

W = 2x² + 4x + 1

L = 8 − x

Area is width times length.

A = (2x² + 4x + 1) (8 − x)

If you wish, you can simplify with distribution.

A = 8 (2x² + 4x + 1) − x (2x² + 4x + 1)

A = 16x² + 32x + 8 − 2x³ − 4x² − x

A = -2x³ + 12x² + 31x + 8

What is the difference of 8 times a number r and 12?
lapo4ka [179]

Answer:

The difference of 8 times a number r and 12 is solved for a number r and is given by r=\frac{3}{2}

Step-by-step explanation:

Given problem is the difference of 8 times a number r and 12

It can be written as

(8\times r)-12

To simplify the above expression :

8r-12

8r-12=0

8r-12+12=0+12 ( using addition property of equality )

8r=12

8r(\frac{1}{8})=12(\frac{1}{8}) (using division property of equality )

r=\frac{3}{2}

Therefore r=\frac{3}{2}

Therefore the difference of 8 times a number r and 12 is solved for a number r and is given by r=\frac{3}{2}

There are 22 soccer balls, and each bag holds 6 balls. how many bags does rico completely fill ? how many soccer are left?
muminat

Answer:

3 bags and 4 soccer balls leftover.

Step-by-step explanation:

Divide 22 by 6 and use only the number before the decimal. This means you need 3 bags.

Now multiply 3 by 6 to see how many soccer balls were put in bags. (18)

Now subtract 18 from 22 and you have the number of balls leftover. (4)
