20 + 17y = -6 + 15y
First, regroup your terms.
Second, take away '15y' from each side.
Third, subtract '17y - 15y' to get '2y'.
Fourth, take away '20' from both sides.
Fifth, simplify '-6 - 20' to get '-26'.
Sixth, divide both sides by '2'.
Seventh, how many times goes 2 go into 26? 26 ÷ 2 = 13.
Answer:
y = -13
Answer:
The intersection is 
.
The Problem:
What is the intersection point of 
and 
?
Step-by-step explanation:
To find the intersection of and , we will need to find when they have a common point; when their 
and 
are the same.
Let's start with setting the 's equal to find those 's for which the 's are the same.
By power rule:
Since 
implies 
:
Squaring both sides to get rid of the fraction exponent:
This is a quadratic equation.
Subtract 
on both sides:
Comparing this to 
we see the following:
Let's plug them into the quadratic formula:
So we have the solutions to the quadratic equation are:
or 
.
The second solution definitely gives at least one of the logarithm equation problems.
Example: 
has problems when 
and so the second solution is a problem.
So the where the equations intersect is at .
Let's find the -coordinate.
You may use either equation.
I choose .
The intersection is .
Answer:
Number 5. = 69
Number 8. = 19
Step-by-step explanation:
Answer:
It's $32.39.
Step-by-step explanation:
35.99 - 35.99*10% =
=35.99 - 35.99*0.1
=35.99 - 3.599
=32.391
32.391 is close to 32.39 so we will round it to that number.
The answer is $32.39.
