The function and its inverse are exactly the same. You find the inverse of a function by switching the x and the y and then solving for the new y. If your function is y = -x + 5 and you switch the x and the y, you get x = -y +5. Now solve for the new y to get y = -x + 5. The domain and range for those is all real numbers.
Volume of Square Based Pyramid = (1/3)*(Side Length of Base)^2 *(height)
the given information are:
Volume = 120
height = 10
plug this in and get:
120 = (1/3)*(side)^2 *(10)
12 = (1/3)*(side)^2 [divided both sides by 10]
36 = (side)^2 [multiplied both sides by 3]
(side) = 6 [square rooted both sides]
Therefore the Side Length of the Base is 6 meters.
Answer:
The number of drinks that Sarah bought was 2 and the number of candies that Sarah bought was 6
Step-by-step explanation:
Let
x ----> the number of drinks that Sarah bought.
y ----> the number of candies that Sarah bought.
we know that
she bought $35.50 worth of drinks and candies
so
-----> equation A
She bought 3 times as many candies as drinks.
so
-----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (2,6)
see the attached figure
therefore
The number of drinks that Sarah bought was 2 and the number of candies that Sarah bought was 6
