Answer:
y = 250x +5000
Step-by-step explanation:
The "initial" enrollment is 5000, when x=0 years after 1960.
The rate of change of enrollment is ...
change of enrollment / change in time
= (15000 -5000)/(2000 -1960)
= 10000/40 = 250 . . . . students per year
Then the desired equation is ...
y = 250x + 5000
<em>Answer:</em>
<em>(r + 9)(r - 3)</em>
<em>Step-by-step explanation:</em>
<em>r² + 6r - 27 =</em>
<em>= r² + 9r - 3r - 27</em>
<em>= r(r + 9) - 3(r + 9)</em>
<em>= (r + 9)(r - 3)</em>
