Answer:

You can tell when a formula represents each of these by the number of dimensions that are multiplied in the calculation.

Ex:

d = 2r (this would only involve multiplying by one dimension, therefore it is a length)

A = bh (this involves multiplying 2 dimensions, giving a measurement of area)

V = lwh (this involves multiplying 3 dimensions, giving a measurement of volume)

Betty's grade in science class is affected by the number of missing assignments. The table below shows the science grade percent

Hi!

$y=-5x+95$

Plug in $15$ for $x$

$y=-5(15)+95$

Multiply $-5$ and $15$

$y=-75+95$

Add $-75$ and $95$

$y =15$

-------------------------------------------------------------------------------------------------------------

Betty's percentage is 15%.

The rate of change is the amount it changes for every missing assignment, therefore it would be -5.
