Front

What is the formula to determine the total cost of purchasing s computers and p printers?

Back

The formula is T = 581s + 150p.

Front

How can you isolate p in the equation T = 581s + 150p?

Back

p = \frac{T - 581s}{150}.

What is the largest integer value such that f(x) ≤ g(x) for the given functions?

Back

The largest integer value is 6.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, for any two points x1 and x2 where x1 < x2, f(x1) < f(x2).

Front

What is the definition of a zero of a function?

Back

A zero of a function is a value of x for which f(x) = 0.

Front

How do you solve a system of equations graphically?

Back

You graph both equations and find the point(s) where they intersect.
