Let n represent the interger l, the three consective intergers are represented by
The second one represent
Simplify both sides
The intergers are 16,18,20
The number of books which Mr. Hartzel has now is:
<h3>What is Algebra?</h3>
This refers to the use of calculations to solve mathematical problems. There are different ways in which algebra is used and this can include addition, subtraction, division, etc.
With this in mind, we can see that Mr Hartzel had 12 books in his library
Then he got 9 new books and then sold off 6 books.
Therefore, the total number of books which he has now is:
12+9-6= 15 books

Answer:
See explanation below
Step-by-step explanation:
Explain what is the difference between the solutions to 2x=10 and 2x > 10
Given the equations;
2x = 10
x = 10/2
x = 5
For the equation 2x > 10
x > 10/2
x > 5
The first equation has only one solution which is 5 while the second equation has infinite number of solutions since the values of x can take any value that is greater than 5
Answer:
y = - 2x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
Calculate m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1,1)
m = 
= - 2
note the line passes through (0, 3) ⇒ c = 3
y = - 2x + 3 ← equation in slope-intercept form
