Montrer que le carré d un nombre pairest un nombre pair
Answer:
soit n un nombre entier quelconque; 2n sera pair et 2n+1 sera impair.
1) (2n)² = 4n² = 2 * 2n²
2) (2n+1)² = 4n² + 4n + 1 = 2*(2n² + 2n) + 1
3) 2n + 2m = 2*(n+m)
la somme de 2 nombres pairs est paire
(2n + 1) + (2m + 1) = 2n + 2m + 2 = 2 *(n + m + 1)

[tex]y = \dfrac{x}{2} - 6[/tex]Write an equation of the line that passes through each pair of points.
(-3,9), (-3,-5)
** Will mark brainliest, please show work!**
Answer:
y = 0x - 5 or just y = -5
Step-by-step explanation:
use the slope intercept equation
y2 - y1
x2 - x1
- 5 - 9 = 14
-3 + 3 = 0
14 / 0 = 0
so the slope is undefined
take one of the points (let's use -3, -5) and plug that in the slope intercept form (y = mx+b)
so -5 = 0(-3)+b
0 • 3 = 0 so the b (or y intercept) equals -5
so the equation is y = -5

The price of a pair of pants was reduced from $30 to $12. By what percentage was the price of the pair of pants reduced?
Answer:
Well to calculate percentage decrease
(Starting value- ending value / starting value)* 100
so 30-18=12
12/30= 2/5
2/5*100= 200/5
40 percent
Now thats the amount lost so
100%-40%=60%
60% reduction

State the range in proper interval notation
Answer:
the range in interval notation is (-4, 4).
Step-by-step explanation:
"Range" refers to the set of numbers that contains all possible values of y that a given function can take on. In this diagram we see that the smallest possible y-value is -4 and the largest is +4, not inclusive (the set does not contain either -4 or +4). Thus, the range in interval notation is (-4, 4).

Answer:
[tex]\dfrac{2}{8}=25\%[/tex]
Answer: 2/8 (1/4 simplified.) 0.25(decimal form)
Step-by-step explanation:
If 6/8 are dog bones, then we subtract 8/8-6/8. We get 2/8. If the fraction needs to be simplified, then we get 1/4. If a decimal is needed, then we divide 2 by 8. We get 0.25.

Any Help On This Would Make Me So Grateful
Decide if the following statement is valid or invalid. If two sides of a triangle are congruent then the triangle is isosceles. In ABC AB=BC so ABC is isosceles. Show work if you can
Answer:
Step-by-step explanation:
Properties of an Isosceles Triangle
(Most of this can be found in Chapter 1 of B&B.)
Definition: A triangle is isosceles if two if its sides are equal.
We want to prove the following properties of isosceles triangles.
Theorem: Let ABC be an isosceles triangle with AB = AC. Let M denote the midpoint of BC (i.e., M is the point on BC for which MB = MC). Then
a) Triangle ABM is congruent to triangle ACM.
b) Angle ABC = Angle ACB (base angles are equal)
c) Angle AMB = Angle AMC = right angle.
d) Angle BAM = angle CAM
Corollary: Consequently, from these facts and the definitions:
Ray AM is the angle bisector of angle BAC.
Line AM is the altitude of triangle ABC through A.
Line AM is the perpendicular bisector of B
Segment AM is the median of triangle ABC through A.
Proof #1 of Theorem (after B&B)
Let the angle bisector of BAC intersect segment BC at point D.
Since ray AD is the angle bisector, angle BAD = angle CAD.
The segment AD = AD = itself.
Also, AB = AC since the triangle is isosceles.
Thus, triangle BAD is congruent to CAD by SAS (side-angle-side).
This means that triangle BAD = triangle CAD, and corresponding sides and angles are equal, namely:
DB = DC,
angle ABD = angle ACD,
angle ADB = angle ADC.
(Proof of a). Since DB = DC, this means D = M by definition of the midpoint. Thus triangle ABM = triangle ACM.
(Proof of b) Since angle ABD = angle ABC (same angle) and also angle ACD = angle ACB, this implies angle ABC = angle ACB.
(Proof of c) From congruence of triangles, angle AMB = angle AMC. But by addition of angles, angle AMB + angle AMC = straight angle = 180 degrees. Thus 2 angle AMB = straight angle and angle AMB = right angle.
(Proof of d) Since D = M, the congruence angle BAM = angle CAM follows from the definition of D. (These are also corresponding angles in congruent triangles ABM and ACM.)
QED*
*Note: There is one point of this proof that needs a more careful “protractor axiom”. When we constructed the angle bisector of BAC, we assumed that this ray intersects segment BC. This can’t be quite deduced from the B&B form of the axioms. One of the axioms needs a little strengthening.
The other statements are immediate consequence of these relations and the definitions of angle bisector, altitude, perpendicular bisector, and median. (Look them up!)
Definition: We will call the special line AM the line of symmetry of the isosceles triangle. Thus we can construct AM as the line through A and the midpoint, or the angle bisector, or altitude or perpendicular bisector of BC. Shortly we will give a general definition of line of symmetry that applies to many kinds of figure.
Proof #2 (This is a slick use of SAS, not presented Monday. We may discuss in class Wednesday.)
The hypothesis of the theorem is that AB = AC. Also, AC = AB (!) and angle BAC = angle CAB (same angle). Thus triangle BAC is congruent to triangle BAC by SAS.
The corresponding angles and sides are equal, so the base angle ABC = angle ACB.
Let M be the midpoint of BC. By definition of midpoint, MB = MC. Also the equality of base angles gives angle ABM = angle ABC = angle ACB = angle ACM. Since we already are given BA = CA, this means that triangle ABM = triangle ACM by SAS.
From these congruent triangles then we conclude as before:
Angle BAM = angle CAM (so ray AM is the bisector of angle BAC)
Angle AMB = angle AMC = right angle (so line MA is the perpendicular bisector of BC and also the altitude of ABC through A)
QED
Faulty Proof #3. Can you find the hole in this proof?)
In triangle ABC, AB = AC. Let M be the midpoint and MA be the perpendicular bisector of BC.
Then angle BMA = angle CMA = right angle, since MA is perpendicular bisector.
MB = MC by definition of midpoint. (M is midpoint since MA is perpendicular bisector.)
AM = AM (self).
So triangle AMB = triangle AMC by SAS.
Then the other equal angles ABC = ACB and angle BAM = angle CAM follow from corresponding parts of congruent triangles. And the rest is as before.
QED??
Yes, This statement is valid.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The two sides of a triangle are congruent.
Then, In ΔABC;
⇒ AB ≅ BC
So, ΔABC is isosceles.
Now,
Since, The two sides of a triangle are congruent.
We know that;
In a triangle if two sides are equal then it is an Isosceles triangle.
So, The given statement '' ΔABC is isosceles'' is valid.

3/4 divided by 5/6=
Answer:
The answer is 9/10.
Step-by-step explanation:
Step 1: 3/4/5/6. This means, 3/4 is being divided by 5/6 and so you write it in that form. Take this for an example. 2/4 divided by 3 is 2/4/3.
Step 2: 3/4 ÷ 5/6. This is because, we want the question to be easy to simplify. Also, we want to write the division question as a multiplication problem. And this sign ( / ) means to divide.
Step 3: 3/4 × 6/5. This is because in Maths, when a fraction is dividing another fraction, that fraction is reciprocated ( the fraction at the right side.) Reciprocated here means the denominator is made the numerator and the numerator is made the denominator.
Step 4: 3/2 × 3/5. How? We cancelled out. 2 goes into 4 twice and into 6 thrice.
Step 5: 9/10. We multiplied 3/2 × 3/5 to get 9/10.

Answer:
[tex]-(\frac{3}{7})^3[/tex]
Step-by-step explanation:
Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.
[tex]-1 * (\frac{3}{7})^3[/tex]= [tex]-1 * \frac{3}{7} * \frac{3}{7} * \frac{3}{7}[/tex]
We then multiply by -1 to (3/7)^3 to get the exact answer.
