Mr. Chavez has some $1 bills and some $5
bills. In all, he has 6 bills worth $22. A
system of equations that can be used to
determine how many of each bills Mr.
Chavez is
y = 30 – 5x
y = 22 - x
Where x is the number of $1 bills
and y is the number of $5 bills.
Find the values of x and y.

The polynomial function of least degree with a leading coefficient of 1 is: f(x) = x3 + ax2 + bx + c

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
