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:
look its really simple like if there is written the father age is two times than its son and its is also said sum of their age becomes 25 then
Step-by-step explanation:
solution,
let father and son age be x and y
2x =y ---------------(i)
x+y=25----------------(ii)
now,
putting the value of y in equation two we get,
x+(2x)=25
3x=25
x=25/3
x=8 yrs ( using round off)
again,
2x = y
2×8=y
16=y
therefore, father age is 16 and son age is 8

Answer:
y = 6.50x + 6 or 71 = 6.50x + 6
10 people are the max you can invite
Step-by-step explanation:
We have the simple equation
y = 6.50x + 6
6.50x because it it per person
6 because it is a flat one time charge
We want the max to be 71 so that will be our y
71 = 6.50x + 6
We are now going to solve for x
65 = 6.5x
x = 10
