Jacob North wants to buy a four-year-old Palomino sedan. His friend has a V8 four door
that he will sell Jacob (wholesale). The car has a
manual transmission and DVD player, leather
seats, power sunroof and 53,480 miles. Premier
Certified Pre-Owned Autos has a V6 four-door
they are selling (retail). The car has power
mirrors, front bucket seats, aluminum wheels and
73,840 miles. It does not have air conditioning.
Which car will cost Jacob the least amount to
purchase?

(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
