Denise --

There appears to be a large amount of information missing here:
*  in #107 the formula for tax is given for income under $109,450 --
but then you ask about a $150,000 income
*  in #49 is that (-y)*(-y) or is it (-y)-(-y) or is it (-y)^(-y) ?
*  in #11, #12, they appear to be true-false questions.  Is that true or false?
*  is #63 really the following -- -2 - 4*(2 - 3.5) ?  Or are there
other missing operators?

Best regards,

Simplify each expression
107. Married filling Jointly. The expression 0.15(43,850) + 0.28(x-43,850)
gives the 2000 federal income tax for a married couple filing jointly
with a taxable
income of x dollars, where x is over $43,850 but not
$105,950.(www.irs.gov)
a) Simply the expression
b) Use the expression to find the amount of tax for a couple with a
taxable income of $80,000


49. Simplify the expression
(-y)(-y)
example:3(5x) = (3*5)x
              = (15)x
              = 15x

11. and 12. are true and false

63. Yes it is -2-4(2-3*5)

This is my first attempt at answering a google question, so let me know how I do.

49.  (-y)(-y) = y^2        (y squared)

82.  4m-5-(m-2)= 3m - 3

107a.  0.15(43,850) + 0.28(x-43,850) = 6577.5 + 0.28x - 12278 = 0.28x - 5700.5
107b.  if x = 80000, then 0.28(80000) - 5700.5 = $16,699.5
107c. and 107d.  If you can provide the units of the horizontal and
vertical axis in the graph, I can tell you how to use the graph to
find the answer (for example, are they in years, dollars, or tax
rates?)

108a.  0.15(26,250) + 0.28(x - 26,250) = 0.28x - 3412.5
108b.  if x = 40000, then 0.28(40000) - 3412.5 = $7,787.5
108c.  Two singles pay 2($7,787.5) = $15,575 which is less than
$16,699.5.  So married couples pay more.

11.  This is not a complete sentence.

12.  A rational number is a number that can be expressed as a fraction
p/q where p and q are integers and q is not equal to zero.  Since 0.25
can be expressed as 1/4, the answer is True.

63.  -2-4(2-3*5) = -2 - 4*2 + 4*3*5 = -2 - 8 + 60 = 50


If you need further clarification, please don't hesitate to say so.


AC

11. FALSE -- if it's intended to read "the set of counting  numbers
smaller than the national debt is infinite."  These are the integers,
and while several trillion dollars would take a long time to count,
the number IS NOT infinite.
12.  TRUE -- here's the definition of a rational number and since 0.25
can be expressed as 1/4, it's a rational number:
"A number capable of being expressed as an integer or a quotient of
integers, excluding zero as a denominator."
