My teacher asked us to create a rollercoaster with these requirements : - your roller coaster ride must have 2 maxima and 2 minima.
- the ride length must be equal to 1.5 minutes.
- Consider the initial point of the roller coaster is the origin of the graph (0;0)
- The roller coaster moves horizontally from the origin for 500 meters before it starts going up.
- the ride dives below the ground into a tunnel at least once.
- the average speed of your rollercoaster is 40m/s.
- include the following in your design: one double root (multiplicity of two) and 2 real roots.
-Write the complete factored form of your roller coaster polynomial.
- Find the equation in standard form that represents your roller coaster ride.
- Perform synthetic division to verify the correctness of your equation.
- Draw an accurate graph of your polynomial.

(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

step-by-step explanation:

when you realize that you dont know just realize i just took a test and im so smart

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221
