A.) x = # of bottles
Fill It Up, Inc.: y = 4x
Bottles by Bob, Co.: y = 3x + 25

b.) x is the independent variable, and y is the dependent variable because it depends on the value of x. See picture below for graphs.

c.) Not sure if the class size is given, but if there are less than 25 students then Fill It Up, Inc. would be cheapest. However, if there are more than 25 students then Bottles by Bob, Co. would be cheapest. This is shown in the graph. The class size influenced the decision.

d.) The intersection in the graphs at point (25, 100) shows that for 25 bottles the price will be the same ($100).

A thermodynamic analysis of a proposed brayton cycle gas turbine yields p=5 mw of net power production

lina2011 [118]

The Brayton cycle is a thermodynamic cycle named after George Bailey Brayton that describes the workings of a constant pressure heat engine. The original Brayton engines used a piston compressor and piston expander, but more modern gas turbine engines and air breathing jet engines also follow the Brayton cycle.

Which graph below represents a functional relationship? A. 10 10 8 8 6 6 4 2 2 X 10864 6 8 10 10 8 6 4 4 6 8 10 -21 4 -61 -8 -8

Answer:

Graph (C)

Step-by-step explanation:

To find whether the graph\table represents a relationship or a function we have to analyze the input-output values given.

Graph A.

In this graph for every input value (x-value) there are two output values (y-values).

For x = -2, y = -2, 2

So the graph doesn't represent a function.

Graph B.

For every x value there are two y-values

For x = -5, y = -3, 3

So the graph doesn't represent a function.

Graph C.

For every input value there is a different y-value.

Therefore, graph represents a function.

Graph D.

In this graph for x = 3, y = 1, 2, 3, 4

For one value of x, there are four values of y.

Therefore, graph doesn't show the relationship.

Use the drop-down menus to complete each equation so the statement about its solution is true. I’ll give brainliest :))

melisa1 [442]

Step-by-step explanation:

5 - 4 + 7x + 1 = 7x + 2.

If there are no solutions, then it is of the form 7x + c, where c is any real number besides 2.

If there is 1 solution, then it is of the form mx + c, where m is any real number besides 7 and c is any real number.

If there are infinitely many solutions, then it is of the form 7x + 2.
