Brianna's thinking is wrong because obviously all of the expressions are going to equal -4 when x is 0 because -4 would be the only value. Also, if x was a different number, the expressions wouldn't be equivalent. The equivalent expressions are A. 9x - 3x - 4, and C. 5x + x - 4. This is because when both are simplified, they equal 6x - 4.

we have

we know that
<u>The Rational Root Theorem</u> states that when a root 'x' is written as a fraction in lowest terms

p is an integer factor of the constant term, and q is an integer factor of the coefficient of the first monomial.
So
in this problem
the constant term is equal to 
and the first monomial is equal to
-----> coefficient is 
So
possible values of p are 
possible values of q are 
therefore
<u>the answer is</u>
The all potential rational roots of f(x) are
(+/-)
,(+/-)
,(+/-)
,(+/-)

Answer:
<h2>y = x - 3</h2>
Step-by-step explanation:
4x - 5 = 7 + 4y <em>subtract 7 from both sides</em>
4x - 5 - 7 = 7 - 7 + 4y
4x - 12 = 4y <em>divide both sides by 4</em>
4x/4 - 12/4 = 4y/4
x - 3 = y
