D(-1,-1), E(-8,-4), F(-8,-8)
Can someone tutor me too!!!
Answer:
D. 9n = 27
Step-by-step explanation:
If we need one adult for every 9 students, we can represent that as 9n:
if n is the number of adults.
Because we have 27 students, the equation 9n = 27 works.
A better way of formatting the equation is:
n = 27/9
Because it directly shows what the number of adults is, but with some reformatting, it is clearly the same equation.
Here’s an explanation: The average rate of change of a continuous function, f(x) , on a closed interval [a,b] is given by. f(b)−f(a)b−a.
It would be less then 20%
