Here's the graph of your equation, instructions on how to plot is in the image. if there's a second line equation, you could use the method shown to plot that too, and the x and y values of the intersection point would be your answer. 

you could also use algebra to simultaneously solve the two equations to obtain x and y as well, feel free to ask!

hope that helps :) sorry it's not a definite answer

Answer:

   ACBD-BDAC

Step-by-step explanation:

It is convenient to compare the values of each of the functions when h=1. On the graphs, find 1 on the horizontal axis, then read the value of the function at that point from the vertical axis.

For the equations, the value for h=1 will be its coefficient in the equation.

__

1) a: 80,b: 50, c: 75, d: 30

Fastest to slowest is ACBD.

__

2) a: 4, b: 2, c: 8, d: 3

Slowest to fastest is BDAC

__

The code is these lists, separated by a dash: ACBD-BDAC.

If the vertices of / are B(–3, 3), C(3, 5), and D(–1, 0), what is the perimeter
Rasek [7]
Best is to draw a sketch of the three points.
Next step is to find the distances BC, CD, DB.
The perimeter is the sum of the three distances.

The distances are found using the distance formula:
D=sqrt((y2-y1)^2+(x2-x1)^2)
order of (x1,y1), (x2,y2) is not important.
BC=sqrt((3- -3)^2+(5-3)^2)=sqrt(6^2+2^2)=sqrt(40)=5.324
CD=sqrt((-1-3)^2+(0-5)^2)=sqrt(4^2+5^2)=sqrt(41)=6.403
DB=sqrt((-3- -1)^2+(3-0)^2)=sqrt(2^2+3^2)=sqrt(13)=3.606
So perimeter = BC+CD+DB=16.333  (approximately)
