Which of the following could be the equation of a line parallel to the line y = 4 ? A- undefined
B- y=0
C- x=4
D- y=4x

Option B: is the equation of the line parallel to the line

The general equation of a line is where, is the slope of the line and is the constant.

For a line to be parallel with the line , the slope must be equals to .

So, is the only option in which the slope is equals to zero and so, it is parallel to the line .

B

Step-by-step explanation:

y = 4 is a horizontal line parallel to the x- axis

A parallel line must also be horizontal with equation

y = c ( c is the value of the y- coordinates the line passes through )

The only equation in this form is

y = 0 ( the equation of the x- axis ) → B

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

the answer is:

mean: 6

mad: 2.14
