Imagine the graph for the relation 4x-5y+20 = 0.<br> What would be its slope?
muminat
4x - 5y + 20 = 0
<u>             - 20  - 20</u>
        4x - 5y = -20
 4x - 4x - 5y = -20 - 4x
              -5y = -20 - 4x
              <u>-5y</u> = <u>-4x - 20</u>
               -5         -5
                 y = ⁴/₅x + 4
The slope would be ⁴/₅.

there are 16 bactiria in a beaker and four hours later there are 228 bacteria in the beaker. what is the rate of change per hour
Dominik [7]

Write and solve the appropriate exponential equation:

228 = 16(r)^4, where r is the change per hour in the number of bacteria:

228

------ = r^4     =   14.25.  

 16

Taking the fourth root of both sides, we get:  r = 1.94 (answer)
