Answer:

1/2

Step-by-step explanation:

It's easier to work this problem if you write it as follows:

-4 -5

----- * ------

5 8

Since we have (-)(-) here, the end result is positive.

Cancel the 5s and reduce the fraction 4/8 to 1/2, obtaining 1/2 as your final answer.

How do you do this equation: 9|5x+8|=54

Sergio [31]

Answer (2 answers):

x = -2/5, x = -14/5

Step-by-step explanation:

First step is to try and get the absolute value by itself on one side and everything else that's not inside the absolute value on the other side.

9|5x+8|=54

|5x+8| = 54/9

|5x+8| = 6

Remember how absolute values turn everything positive? For example

|-4|=4, but |4|=4 as well. So we must do the same to our problem by splitting up the absolute equation into two parts.

|5x+8| = 6 and |-(5x+8)| = 6

now solve the first equation.

(Just remove the absolute value sign and solve it normally)

5x+8 = 6

5x = -2

x = -2/5

Now solve the other equation

-(5x+8) = 6

-5x - 8 = 6

-5x = 14

x = -14/5

Anahid can purchase 9 drawing tablets for $10.26 at the art supply shop. She can purchase 21 of the same tablets for $23.52 from

bazaltina [42]

Buying from the website is a better deal.

The amount saved <u>per tablet</u> by purchasing at the vendor with the better deal is $0.02

<h3>Calculating cost </h3>

From the question, we are to determine the better deal

From the given information,

Anahid can purchase 9 drawing tablets for $10.26 at the art supply shop

The unit price at the art supply shop is

$10.26/9 = $1.14

Also,

She can purchase 21 of the same tablets for $23.52 from a website

The unit price from the website is

$23.52/21 = $1.12

Since, the unit price from the website is lesser, it is the better deal

The amount saved per tablet by purchasing at the vendor with the better deal is

$1.14 - $1.12 = $0.02

Hence, buying from the website is a better deal.

The amount saved <u>per tablet</u> by purchasing at the vendor with the better deal is $0.02

Plz help!<br><br> According to the graph, what are the domain and range of f(x)

notsponge [240]

Answer:

Domain: [0, 40]

Range: [0, 20]

General Formulas and Concepts:

<u>Algebra I</u>

Domain is the set of x-values that can be inputted into function f(x)
Range is the set of y-values that are outputted by function f(x)
Interval Notation - [a, b] denotes inclusive, (a, b) denotes exclusive

Step-by-step explanation:

According to the graph, we see that our x-values span from 0 to 40. Since both are closed dots, they are included in the domain:

Interval Notation [0, 40]

Inequality Notation 0 ≤ x ≤ 40

According to the graph, we see that our y-values span from 0 to 20. Since both are closed dots, they are included in the range:

Interval Notation [0, 20]

Inequality Notation 0 ≤ y ≤ 20
