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.
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.

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

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 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
