A student can text 252 words in 4.5 minutes. what is the unit rate in words per minute

56 wpm

Step-by-step explanation:

Hi!

Well the unit rate would just be words per minute or wpm.

In this case wpm or w is 252.

The number of minutes or m is 4.5.

w/m=your wpm

252/4.5=56

56 wpm

Hope this helped, have a great day! <3

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
