If a quadrilateral has perpendicular diagonals, then it is a rectangle.

Which of the following arguments is valid with respect to the conditional statement premise above?

1. A quadrilateral is a rectangle.
Therefore, it has perpendicular diagonals.
2. A quadrilateral does not have perpendicular diagonals.
Therefore, it is not a rectangle.
3. A quadrilateral has perpendicular diagonals.
Therefore, it is a rectangle.
4. A quadrilateral is not a rectangle.
Therefore, it does not have perpendicular diagonals.

A. 3 and 4
B. 1 only
C. 1 and 3
D. None of the arguments are valid.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer: this is not a question

step-by-step explanation: this is a answer

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
