What is the goal of a proof by contradiction

1 answer:

7 0

<span>Proof by contradiction is simply a specific way to form indirect proof that will show the validity of someone's argument or position. It begins by someone assuming the opposite of what they propose is true then goes on to prove that the improper assumption simply leads to a contradiction.</span>

Answer:

y=3x-16

Step-by-step explanation:

-3y=-9x+27

y=3x-9

slope: 3

If the graph f(x)= 9x^2+37x+41/3x+5 has an oblique asymptote at y=3x+k what is the value of k

ira [324]

Answer:

$k=\frac{22}{3}$

Step-by-step explanation:

The oblique asymptote of

$f(x)=\frac{9x^2+37x+41}{3x+5}$ ,

We perform the long division as shown in the attachment.

The quotient is;

$3x+\frac{22}{3}$

Comparing to 3x+k

Hence the value of k is $\frac{22}{3}$

Explain why parallelograms are always

Mars2501 [29]

Answer: Parallelogram is a kind of quadrilateral where as there are some quadrilaterals (like trapezoid , kite, .. ) that do not satisfy the properties of parallelograms.

Step-by-step explanation:

A quadrilateral is a closed polygon having fours sides.

A parallelogram is a kind of quadrilateral having following properties:

Its opposite sides and opposite angles are equal.

The sum of adjacent angles is 180°.

The diagonal of parallelogram bisect each other.

A Trapezoid is also a quadrilateral . It has only one pair of parallel sides. (The other one are not parallel).

So , all quadrilaterals not parallelograms.

Therefore, parallelograms are always quadrilaterals but quadrilaterals are sometimes parallelograms because parallelogram is a kind of quadrilateral where as there are some quadrilaterals (trapezoid , kite, .. ) ) that do not satisfy the properties of parallelograms.

plz mark me as brainliest :)
