Suzanne has purchased a car with a list price of $23,860. she traded in her previous car, which was a dodge in good condition, and financed the rest of the cost for five years at a rate of 11.62%, compounded monthly. the dealer gave her 85% of the listed trade-in price for her car. she was also responsible for 8.11% sales tax, a $1,695 vehicle registration fee, and a $228 documentation fee. if suzanne makes a monthly payment of $455.96, which of the following was her original car? dodge cars in good condition model/year 2004 2005 2006 2007 2008 viper $7,068 $7,225 $7,626 $7,901 $8,116 neon $6,591 $6,777 $6,822 $7,191 $7,440 intrepid $8,285 $8,579 $8,699 $9,030 $9,121 dakota $7,578 $7,763 $7,945 $8,313 $8,581 a. 2004 intrepid b. 2008 neon c. 2005 viper d. 2007 dakota

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
