Question

Need help graphing the intersection of two lines and naming the type of system.

Line y1= (1/Pix-4) + (Sqrt(2)/2.1x)
Line y2 = 1.3

Answer 1

can you rewrite the lines using parenthesis?

Answer 2

Is the format wrong?

Answer 3

\[\frac{ 1 }{ \Pi(x) - 4 } + \frac{ \sqrt{2} }{ 2.1(x) }\]

Answer 4

That is what y1 looks like, if that helps.

Answer 5

intersection would just be y1=y2
solve for x

Answer 6

as for graphing, y2 is just a line
make a chart for y1

or use a graphing calculator seeing how hte numbers are a bit ridiculous

Answer 7

Line y1= (1/Pix-4) + (Sqrt(2)/2.1x)
Line y2 = 1.3
The two lines intersect when they are equated together.
so...
1.3 = (1/Pix-4) + (Sqrt(2)/2.1x)
2.73x = ((2.1x)/(pix-4)) + sqrt(2)
2.73x = 2.1x + (pix -4)(sqrt(2))
.63x = pix(sqrt(2) - 4sqrt(2)
-3.812882938x = -4sqrt(2)
x = 1.483616031

i used the whole value of pi.
y is given

Answer 8

or you can use the graphing calculator.

Answer 9

My study plan is requesting two values of x. I tried an emulator calculator, ti-83, and it is producing a "heartbeat" intersecting at more than one point, so I think I am entering it wrong. franciscanmonk, your solution looks really accurate, but is there another x value?

Answer 10

x=1.8
x=.351
