Answer:
Does not represent a polynomial
Step-by-step explanation:
Answer: the correct option is
(D) The imaginary part is zero.
Step-by-step explanation: Given that neither a nor b are equal to zero.
We are to select the correct statement that accurately describes the following product :
We will be using the following formula :
From product (i), we get
![P\\\\=(a+bi)(a-bi)\\\\=a^2-(bi)^2\\\\=a^2-b^2i^2\\\\=a^2-b^2\times (-1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{since }i^2=-1]\\\\=a^2+b^2.](https://tex.z-dn.net/?f=P%5C%5C%5C%5C%3D%28a%2Bbi%29%28a-bi%29%5C%5C%5C%5C%3Da%5E2-%28bi%29%5E2%5C%5C%5C%5C%3Da%5E2-b%5E2i%5E2%5C%5C%5C%5C%3Da%5E2-b%5E2%5Ctimes%20%28-1%29~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~%5B%5Ctextup%7Bsince%20%7Di%5E2%3D-1%5D%5C%5C%5C%5C%3Da%5E2%2Bb%5E2.)
So, there is no imaginary part in the given product.
Thus, the correct option is
(D) The imaginary part is zero.
Answer:
Step-by-step explanation:
When given a point and a slope, the best equation to use is the point-slope formula, y - k = m(x - h)
which here becomes:
y - 0 = m(x + 1), or y = (-2/3)(x + 1), or y = (-2/3)x - 2/3
If you want this in standard form, first clear the fractions by multiplying all terms by 3: 3y = -2x - 2
Now add 2x to both sides, obtaining: 2x + 3y = -2 (in "standard form."
Simply plug in -15 for x in our given equation.
-x + 2y = -1
-(-15) + 2y = -1
Simplify.
15 + 2y = -1
Subtract 15 from both sides.
2y = -1 - 15
Simplify.
2y = -16
Divide both sides by 2
Y = -8
