If neither a nor b are equal to zero, which answer most accurately describes the product of (a + bi)(a - bi)?
Scrat [10]

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 :

P=(a+bi)(a-bi)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We will be using the following formula :

(x+y)(x-y)=x^2-y^2.

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.

So, there is no imaginary part in the given product.

Thus, the correct option is

(D) The imaginary part is zero.

5(y+2) = 13+ 4(2y-1)<br> please help me with this
Nimfa-mama [501]
Goal:  solve for y.  First step:  Multiply out 5(y+2) and also 4(2y-1):

5y + 10                      and             8y - 4

Then your original    <span>5(y+2) = 13+ 4(2y-1)

becomes   5y + 10 = 13 + 8y - 4

Combining the y terms:    </span>10 = 13 + 3y - 4

Simplifying the right side:  10 = 3y + 9

Subtracting 9 from both sides:  1 = 3y.  Solving for y:  y = 1/3

Find the slope and the y-intercept of the line: 6x + 7y = 52
CaHeK987 [17]

Answer:

Slope is -6/7

Y-intercept is 52/7

Step-by-step explanation:

6x + 7y = 52

6x - 6x + 7y = 52 -6x

1/7 (7y = -6x + 52) 1/7

y = -6/7x + 52/7
