What is the average rate of change for ƒ(x) = −2x + 70 over the interval 2 ≤ x ≤ 6?
1 answer:
Answer:
The average rate of change is -2
Step-by-step explanation:
we know that
To find out the average rate of change, we divide the change in the output value by the change in the input value.
In a linear function the average rate of change is a constant and is equal to the slope of the function
The linear function in slope intercept form is equal to
where
m is the slope or unit rate of the linear function
b is the y-intercept or initial value of the linear function
In this problem we have
so
therefore
The average rate of change is -2

Answer:
The two numbers are 476 and 284
Step-by-step explanation:
Given:
He used an even number of blocks
The number of blocks is between 700 and 800
The number of blocks is the sum of two
To Find :
Two number = ?
Solution:
The sum of an odd number and an even number id always odd. So 423 can be eliminated
So two numbers must be any of the 4 remaining options
Its also given that the number lies between 700 and 800. So the sum should be greater than 700 and lesser than 800
by trial and error method
352+476 = 828 ( greater than 700 but greater than 800, condition fails)
352+326 = 678 ( lesser than 700 but lesser than 800, condition fails)
352+284 = 636 ( lesser than 700 but lesser than 800, condition fails)
476+326 = 802 ( greater than 700 but greater than 800, condition fails)
476+284 = 760 ( greater than 700 and lesser than 800)
The school net ball team drew 2 matches. The team won of total matches played
Given, A school netball team won ten matches, lost four and drew of the total played
Let the total number of matches played be "n"
Number of matches drawn = of n
<em>Total matches played = number of won matches + number of lost matches + number of drawn matches</em>
Taking "n" as common from left hand side,
So, they played 16 matches in total
Number of matches drawn = of n =
