Answer:
Step-by-step explanation:
Given: a graph
To find: the average rate of change of the amount of the element over the 10-minute experiment
Solution:
A rate of change of one quantity with respect to another quantity is known as rate of change. If y is the dependent variable and x is the independent variable then average rate of change = change in y /change in x.
From the graph,
change in x (time) = minutes
change in y ( amount of the element) = g
So, average rate of change =
Answer:
x = 0 and x = -2 are solutions of the given rational equation.
Step-by-step explanation:
We must solve the following rational equation:
Now we present the procedure:
1) Given
2) Compatibility with multiplication/Existence of the multiplicative inverse/Definition of division/Modulative property.
3) Distributive property/
4) Compatibility with addition/Existence of the additive inverse/Modulative property/Reflexive property
5) Distributive property/
6) Result
Now we check the rational equation with each root:
x = 0
x = 0 is a solution of the rational equation.
x = -2
x = -2 is a solution of the rational equation.
8(8 + X) = 16
64 + X = 16
-64 -64
X = -48
