Answer:
r = p(-b/a)
Step-by-step explanation:
Let p(x) = q(x)(ax + b) + r(x) where q(x) is the quotient when p(x) is divided by ax + b and r(x) is the remainder.
Since ax + b is a first degree polynomial, r(x) is one power less than ax + b is is just a constant, r.
So, p(x) = q(x)(ax + b) + r
Now, p(x) = r when q(x)(ax + b) = 0
since q(x) ≠ 0, ax + b = 0 ⇒ ax = -b ⇒ x = -b/a
⇒ p(x) = r when x = -b/a
So, r = p(-b/a)
So, the remainder when a polynomial function p(x) is divided by a first degree polynomial ax + b is p(-b/a)
Given:
Two electrons are added to each of six atoms in a group.
To find:
The expression for the net change in charge.
Solution:
Charge of atoms = Number protons - Number of electrons.
Let number of atoms be x.
6 atoms = 2 electrons added
1 atom =
electrons added
1 atom =
electrons added
x atoms =
electrons added
Therefore, the net change in charge is represented by the expression
because we subtract number of electrons to find atom charge, where, x is the number of atoms.
6 atoms = 2 protons removed
1 atom =
protons removed
1 atom =
protons removed
x atoms =
protons removed
Therefore, the net change in charge is represented by the expression
, where, x is the number of atoms.

With some extra effort, the radical can be removed from the denominator. That result is

The preferred form would be the one with the radical in the denominator, as it correctly shows the domain of the function to be x ≥ -7. The function actually is defined at x=74, which the "rationalized" form does not show.
Answer:
-7 and -4
Step-by-step explanation:
Simce 11 is a prime number, only 11 and 1 give us eleven and do not add up to give 28 so we find factors of 28 that'll add up to give us negative 11 and multiply to give us 28.
factors of 28: 1,2,4,7,14,28 -1,-2,-4,-7,-14,-28
Remember a positive integer has negative factors as well as a negative value times another negative value gives a positive value.
Two number that add to give -11 will be -4 and -7
