In exercises 8, we have graphed the boundary line for the linear inequality. Determine the correct half-plane in each case, and complete the graph. See attached file for full problem description.
y > 3
Graph each of the following inequalities.
16. 4x + y > = 4
28. 3x - 4y < 12
In exercises 2, evaluate each function for the value specified.
In exercise 18, rewrite each equation as a function of x. -3x + 4y = 11
In exercise 22, graph the functions. f(x) = -2x - 5
In exercises 27 to 32, if f(x) = 4x - 3, find the following:
In exercises 33 to 38, if f(x) = 5x - 1, find the following:
54. Business and finance: If the inventor in exercise 53 charges $4 per unit, then her profit for producing and selling x units is given by function P(x) = 2.25x - 7000
(a) what is her profit if she sells 2000 units?
(b) what is her profit if she sells 5000 units
(c) what is break-even point for sales?
Please see the attached file for detailed solution and graphs.
16. First draw the line 4x + y = 4
Two points are needed to graph a straight line. Usually, we use the x- ...
The solution is comprised of detailed explanations for the chapter 7 section 7.4-7.4 of Beginning Algebra (6th edition). It explains how to graph the linear inequality with two variables in xy-plane in detail. Furthermore, the values of the functions are evaluated. Finally, there is an application problems dealing with profit and break-even.
