Varying inversely means y=a number divided by x
find the number: 7=k/5 =>k=35
so the equation is y=35/x
5m-n
Just replace m with 4 and n with 9
5(4)-9=20-9=11
The y-intercept is where on the graph the line is intersecting the y=axis. Slope is in the form y=mx+b (b=y-intercept, mx=how far up and over.)
Answer:
There are infinite number of triangles that could be achieved with those angles.
To picture this, we only have to imagine a triangle that is either smaller or bigger than the one at hand.
Tracing a series of paralell lines (which guarantee that the angles are being kept), we can draw triangles for infinite values of x,y and z.
