In the equation a = v/r, if a is plotted against v then what will be the shape of the graph? How about if a is plotted against r?

  a) a straight line

  b) a hyperbola

Step-by-step explanation:

a) When a = v/r is plotted against v as the independent variable, it will be a straight line through the origin with a slope of 1/r.

__

b) When a = v/r is plotted against r as the independent variable, it will be a hyperbola with a "constant of proportionality" of v. Here, a is inversely proportional to r.

C.

Step-by-step explanation:

10,3-2x=14,8-3x

x=4,5 - one hamburger

y=1,3 - one milk shake

OR:

$14,8-$10,3=$4,5 - one hamburger

2*4,5+y=10,3

y=1,3 - one milk shake

2y=2,6
