Answer:

c) y = - 2 x +3

d) y = 1/2 x + 1

Step-by-step explanation:

For c) Look for the exression that contains "3" as the y-intercept (the "b" in the form y = m x + b)

The only equation is y = - 2 x +3

For d) try in all equations if replacing x with 2, gives you an answer "2" for y as well.

The only equation that does such is y = 1/2 x + 1

Answer:

$\dfrac{256}{3} = 85 \dfrac{1}{3}$

Spencer is asked to factor the polynomial 256x^4y^2−y^2 completely over the integers. His work is shown below.

mr Goodwill [35]

Answer:

Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.

Step-by-step explanation:

Step 1: Factor

256x^4y^2−y^2

y^2(256x^4 - 1)

y^2(16x^2 - 1)(16x^2 + 1)

y^2(4x + 1)(4x - 1)(16x^2 + 1)

Answer: Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.
