Choose the equation of the line that is parallel to the x axis x=4, x+y=0, x=y, y=4

A line that is parallel to the x-axis will pass through the y-axis, horizontally.

The equation of line parallel to the x-axis is y = 4

A line that is parallel to the x-axis is represented with the following equation

y = n

Where n can be any real number.

In other words, the following equations are parallel to the x-axis

y = 2

y = 3

y = -2

y = 10

And so on

Hence, the equation of line parallel to the x-axis is y = 4

y=4

Step-by-step explanation:

if we draw a function we see that y=4 is paralel to the x axis

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
