Answer:
g(5) = 120
Step-by-step explanation:
to evaluate g(5) , substitute x = 5 into g(x)
g(x) = x³ - x , then
g(5) = 5³ - 5 = 125 - 5 = 120
A. The bread machine you are interested in costs $100 with tax.
The ingredients to make one loaf of bread cost $0.80.
What is the rate of cost of one loaf of bread?
B. What is your start up cost? (cost of machine)
C. Write a linear equation, y = mx + b for the total cost.
D. Graph the equation on the graph provided. You may use either Point Plotting or Slope-Intercept. Be sure to locate at least 3 points. You may want to do this in pencil in case you decide to use more points later in the problem.
Write the equation of the given line in standard form.
x = 3
"Standard form" is the form ...
... ax + by = c
where a, b, c are mutually prime integers. The coefficients a and b cannot both be zero. The leading coefficient must be positive. If "a" is zero, then the leading coefficient is "b".
So ...
... x = 3
is in standard form already. (a=1, b=0, c=3)

Further comments on Standard Form
Of course, if the line has irrational slope or intercept, the coefficients cannot all be integers.
The order of the variables may be swapped, in which case the coefficient of y is the leading coefficient and must be positive.
This is the only way a vertical line can be written, as slope-intercept form is undefined for a vertical line.
