Greg plans to purchase a bicycle. bike a costs $270 and has an expected maintenance cost of $36 per year. bike b costs $360 and has an expected maintenance cost of $20 per year. which statement is true based on the average annual cost of each bike?
bike a is the better choice if greg plans on owning the bike for 5 years or 6 years.
bike b is the better choice if greg plans on owning the bike for 5 years or 6 years.
bike a is the better choice if greg plans on owning the bike for 5 years. bike b is the better choice if greg plans on owning the bike for 6 years.
bike b is the better choice if greg plans on owning the bike for 5 years. bike a is the better choice if greg plans on owning the bike for 6 years.

The Option 'Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years' is true.

Step-by-step explanation:

If x represents number of year and y represents the total cost  of the bike.

According to the question for bike A, total cost, y= 270+36x

And, for bike B, total cost, y= 360+20x

For 5 years price of A = 270 + 36 × 5=270 +180 = 450 dollar

For 5 years price of B= 360+ 20 × 5=360+100= 460 dollar

Thus, for 5 years price of A< price of B

⇒For 5 years Bike A is the better choice than Bike B.

For 6 years price of A = 270 + 36 × 6=270 +216 = 486 dollar

For 6 years price of B= 360+ 20 × 6=360+120= 480 dollar

Thus, for 6 years price of A> price of B

⇒For 6 years Bike B is the better choice than Bike A.

(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

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
