Big Deal appliance store is offering deep discounts on flat screen TVs. On the graph below, the xxx-axis represents the original price, and the yyy-axis represents the new sale price, in dollars. Big Deal's chief competitor, Appliance Hut, has announced that all sale prices (S)(S)left parenthesis, S, right parenthesis on TVs will be determined according to the equation:
S=(0.60)PS=(0.60)PS, equals, left parenthesis, 0, point, 60, right parenthesis, P,
where PPP is the original price.
Which store’s sale is better?

i could probably can you me with a question of mine?

step-by-step explanation:

(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
