Do not lose this assessment. Do all your math on your own paper. Do not write on this assessment.

a. 314,159,654 rounded to nearest million is what?
b. Solve for x:  1/5 + (2/5)x = 3/5
c. Solve for b:  2(3b - 1) = -3(4b - 3)
d. Solve for n:  -2 - 10n = -12 - 4n
e. Briefly describe what a function is.
f. Write a definition for the word domain.
g. Subtract & Simplify:  (-2x^2 + 3x - 5) - (x^2 + 3x - 5)
h. Multiply & Simplify:  -3n(-4n + 7) + 3n^2 + 3n - 10

The next four exercises use expression Q: math - 2ma + 2th + 3htam
[note: m, a, t, h are variables]

r. The ordered-pair (3, -4) is graphed (plotted) in what quadrant?
s. Solve for x:  -91 + x = 91 - x
t. The ordered-pair (-3, 0) implies an input of ___ produces an output of ___.
u. Solve for b:  5b + b + 2 = 5b - b + 8
v. The set of outputs from a function is called the ______.
