For Each Graph Below, State Whether It Represents A Function.

Answers

Answer 1

Answer:

Graph 1, 2, 5, 6 are not functions.

Graph 3, 4 are functions

Step-by-step explanation:

For every input there can only be one output to be a function.

Answer 2

Of the given graphs, only graph[3] and graph[4] represent functions.

What is a function?

A function is a relation between a independent variable and a dependent variable such that the value of dependent variable depends upon the independent one. It is denoted by f(x).

Given are the graphs plotted for different expressions.

Now, for a given expression to be a function, it should have a single unique value of variable [y] in coordination with that of [x]. Of all the graphs given, only the continuous graph[3] and discrete graph[4] have unique or only one unique value of [y] for a value of [x]. So, only graph[3] and graph[4] represent functions.

Therefore, of the given graphs, only graph[3] and graph[4] represent functions.

Salvador sold hats during the weekend sporting event. On Saturday, Salvador sold ( * of the total number of hats. On Sunday, he sold & ( of the total number of hats. What fraction of the total number of hats was left over?

Answers

Answer:

5/28

Step-by-step explanation:

Salvador sold hats during a weekend sporting event. On Saturday, Salvador sold 4/7 of the total number of hats. On Sunday, he sold 1/4 of the total number of hats. What fraction of the total number of hats was left over

Total number of hats = x

Hats sold on Saturday = 4/7x

Hats sold on Sunday = 1/4x

Hats left over = x - (4/7x + 1/4x)

= x - ( 16x+7x/28)

= x - 23/28x

= 28x - 23x/28

= 5/28x

A snail crawls 5/8 inches in 3/4 minute. What is the snail's speed in inches per minute? Write
your fraction in simplest form.

Answers

Answer:

5/12 inches per minute

Step-by-step explanation:

If A snail crawls 5/8 inches in 3/4 minute, then;

5/8 inches = 3/4 minute

we are to fine the distance covered in a minute;

x inches = 1 minute

Divide both expressions

5/8x = 3/4

24x = 20

12x = 5

x = 5/12

Hence the snail covered 5/12 inches per minute

Solve by elimination.
2x + 8y = 60
5x + 4y = –10

Answers

Answer:

2x + 8y = 60= 30

5x + 4y = –10= -2

Step-by-step explanation:

Simplifying

2x + -8y = 60

Solving

2x + -8y = 60

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8y' to each side of the equation.

2x + -8y + 8y = 60 + 8y

Combine like terms: -8y + 8y = 0

2x + 0 = 60 + 8y

2x = 60 + 8y

Divide each side by '2'.

x = 30 + 4y

Simplifying

x = 30 + 4y

find 3/4 of 40

Step-by-step explanation:

A small software development company invests $16,000 to produce a software package that will sell for $50.65. Each unit costs $8.20 to produce. How many units must the company sell to break even? How many units must the company sell to make a profit of $95,000?

Answers

Answer:

376 units and 1,857 units

Step-by-step explanation:

The computation is shown below:

The number of units that company sells to break even is

Let us assume the number of units be x

$16,000  + $8.20x  = $50.75x

$16,000 = $50.75x - $8.20x

$16,000 = $42.55

x = $16,000 ÷ $42.55

= 376 units

Now in order to make the profit the number of units sold is

$50.65x - ($16,000 + $8.20x) = $95,000

$50.65x - $16,000 - $8.20x = $95,000

$42.55x = $95,000 - $16,000

$42.55x = $79,000

x = $79,000 ÷ $42.55

= 1,857 units

Step-by-step explanation:

Let the initial cost of oil be x. After the first year, the price of oil is 1.5x. After the second year, the price of oil is 0.5 ∙ 1.5x = 0.75x.

This is 75 percent of its price at the beginning of the first year.
