Rounding 2 SF would give you 19
Yes you take 3 times 4 and receive 12 and 5 times 4 and receive 20
15
5x-2y=9......(1)
6x+ky=4......(2)
slope of eqn i= -5/-2
=5/2
slope of eqn ii = -6/k
since the line are perpendicular
5/2 * -6/k = -1
-30= -2k
k=15
Answer:
See below.
Step-by-step explanation:
Addition: closed
Example: -5 + 10 = 5, and -5, 10, and 5 are all integers
Subtraction: closed
Example: 10 - 8 = 2, and 10, 8, and 2 are all integers
Multiplication: closed
Example: -4 * 7 = -28, and -4, -7 and -28 are all integers
Division: not closed
Example: 5/2 = 2.5, and 2.5 is not an integer, although 2 and 5 are integers
The set of integers is closed under addition, subtraction, and multiplication because any addition, subtraction, or multiplication of integers always results in an integer.
The set of integers is not closed under division because a division of integers does not always result in an integer.
Answer:
q(x)= 2x+5
r(x)=6
b(x)=x+4
Step-by-step explanation:
I have found what is missing in your question: Rewrite 2x^2+13x+26/x+4 in the form q(x)+r(x)/b(x).
First, we have to divide the polynomial by x+4 and remember that is x times 2x.
By multiplying this we are going to get 
and now we are doing separation of it and getting 
and getting 
Because 5 is showing x times 5 we are going to multiply (x + 4) with 5 and that is 5x + 20.
Now when we can get more simplified we are having:
