Answer:
Solving for y gives:
Step-by-step explanation:
Linear equations are the equations that are degree one equations. When it is asked to solve an equation for a specific variable that means that the specified variable has to be isolated on one side of the equation i.e. in the given question solving for y means isolating y on one side of the equation.
Given equation is:
Multiplication property of equality(Multiplying both sides by q)
Division property of equality(Dividing both sides by 3)
Hence,
Solving for y gives:
Answer: Explanation below.
Step-by-step explanation:
First of all you need to know how to convert a logarithm into an exponential expression. The property is:
This is the same as:
Example 1:
We are trying to find what to raise 9 to, in order to get a result of 9.
When you have same bases, you equal exponents.
Therefore;
Example 2:
In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: which is 2*2*2*2*2
Rewriting this example we have;
Since we have the same base, we equal exponents.
Therefore;
Example 3:
729 can have a base of 3 if expressed as:
