Move all terms containing x to the left side of the equation.
Subtract 3x from both sides of the equation. 2x-3x=−5
Subtract 3x from 2x
−x=-5
Multiply each term in -x=−5 by −1
Multiply each term in −x=−5 by −1
(-x) ⋅ -1=(-5) ⋅-1
X=(-5) ⋅-1
multiple -5 by -1
X=5
Since x=5 is a vertical line, the slope is undefined. Undefined
The equation of a perpendicular line to x=5 must have a slope that is the negative reciprocal of the original slope.
M perpendicular = -1/∞ The negative reciprocal of ∞ is 0
M perpendicular is 0
Since the slope for the perpendicular line is 0 ,the line is perpendicular to the y-axis. The equation of this line is of the form y=c when c is any real number. The equation of the line at point (-2 ,1)
Division by zero is an operation for which you cannot find an answer, so it is disallowed. You can understand why if you think about how division and multiplication are related. But no value would work for x because 0 times any number is 0. So division by zero doesn't work.
So multiplying decimal and whole number means it will always equal as a decimal. But multiplying decimal with decimal means could equal whole or decimal number
