A car travels at a constant speed of 65 miles per hour. The distance the car travels in Miles d, which is a function of time, t.
PolarNik [594]

Answer:

  t(d) = d/65

Step-by-step explanation:

To solve for t, divide by its coefficient:

  d = 65t

  d/65 = 65t/65 . . divide* by 65

  d/65 = t . . . . . . . simplify

Then you can write it in function form if you like:

  t(d) = d/65

_____

* Of course, the rules of equality say you must divide <em>both sides</em> of the equation by the same number.

Is a proportional function f(x) = 5x linear? Why or why not? Explain with an example.
RideAnS [48]

Given two variables x and y, y is directly proportional to x (x and y vary directly, or x and y are in direct variation) if there is a non-zero constant k such that

   y = kx,

The relation is often denoted, using the ∝ symbol, as

   y ∝ x

in this case k = 5/1

Solve -no - 80 &lt; 60 for n. Show the work.
o-na [289]
-np - 80 < 60....add 80 to both sides
-np < 80 + 60
-np < 140...divide both sides by p
-n < 140/p ...now multiply by -1 to make n positive, and change inequality sign
n > -140/p
