2. Match each equation with each situation, then solve each one and state the answer. Equations:
0.9x - 10 - 116
14x + 3x + 150 = 1102
1500 - 120x=660
Situations:
(A) You deposit money in the bank. You withdraw the same amount every month, ending with a certain
amount.
(B) A store is having a sale on car stereos. First a certain percentage is taken off the price, and then the
price is reduced by a fixed number of dollars, resulting in a purchase price.
PIC
(C) Your family is installing carpet on a fixed budget. The costs include the cost of the carpet per square
yard, the cost of the padding per square yard, plus a fixed installation fee.

The sales tax rate is 7.25%. how much tax in dollars is added on an item that costs $56.00? a. $4.06 b. $7.25 c. $14.50 d. $60.06

Find the roots of the polynomial function f(x) = x^3 + 2x^2 + x

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
