Answer:
18.75 is the answer
Step-by-step explanation:
since the internet usage is more than 4 hrs, the second equation will be used. that is
cost = (10 + 2.50 (x - 4)) where x is the usage hours.
thus
An isosceles triangle has a base of 4 and a height of x+3. If the area is 10, what is the value of x?

Hello!
First, let's subtract.
20-1.08=18.92
Now let's add up each of our prices and see which one matches.
A) $19.92
B) $19.67
C) $18.92
D) $18.68
As you can see, our answer matches , so that is our answer.
I hope this helps!
we are given inequalities as
Subtract both sides by 1
so, we get interval as
we have
we can divide both sides by -4
so, we get interval as
now, we can combine them
∪
now, we can draw number line and locate this interval
we get
By definition, the average change of rate is given by:
We will calculate AVR for each of the functions.
We have then:
f(x) = x^2 + 3x interval: [-2, 3]:
f(x) = 3x - 8 interval: [4, 5]:
f(x) = x^2 - 2x interval: [-3, 4]
f(x) = x^2 - 5 interval: [-1, 1]
Answer:
these functions from the greatest to the least value based on the average rate of change are:
f(x) = x^2 + 3x
f(x) = 3x - 8
f(x) = x^2 - 5
f(x) = x^2 - 2x
We will calculate AVR for each of the functions.
We have then:
f(x) = x^2 + 3x interval: [-2, 3]:
f(x) = 3x - 8 interval: [4, 5]:
f(x) = x^2 - 2x interval: [-3, 4]
f(x) = x^2 - 5 interval: [-1, 1]
Answer:
these functions from the greatest to the least value based on the average rate of change are:
