I REALLY NEED HELPPPPP!! Write a paragraph proof for the following conjecture:

Given: m∠ 1 + m∠ 2 = m∠ 4

Prove: m∠3 + m∠1 + m∠2 = 180

Answers

Answer:

Given: measure 1 + measure 2 = measure 4

measure 4 + measure 3 must be 180 degrees because they are supplementary

If measure 4 + measure 3 is 180, and measure 1 + measure 2 = measure 4, we can substitute measure 4 in the first equation for measure 1 + measure 2.

Therefore, we arrive at the answer measure 1 + measure 2 + measure 3 = 180.

I really hoped this helped, and if it did, please consider giving me brainliest.

Select all equations that are equivalent to (5x+6)2=3−(4x+12) .


a. 5x+6=3−(4x+12)

b. (5x+6)2=−4x−9

c. 52x+3=3−(4x+12)

d. (5x+6)2=−4x+15

e. 5x+6=−8x−18

Answers

Answer:

B

Step-by-step explanation:

ita only b .............

The equations that are equivalent to (5x + 6)2 = 3-(4x +12) is (5x+6)2=−4x−9.

Option B is correct.

The very first thing to do is to solve the expression in the given question.

SO,

(5x + 6)2 = 3-(4x +12)

Open brackets

10x + 12 = 3 - 4x - 1210x + 12 = -4x - 9

Collect like terms

10x + 4x = -9 - 1214x = -21

x = -21/14

Now, we will solve each of the given options to determine which one corresponds to the solution to the expression above.

Starting with Option (a)

5x + 6 = 3 - (4x + 12)

Open brackets

5x + 6 = 3 - 4x - 125x + 6 = -4x - 95x + 4x = -9 - 69x = -15x = -15/9

Option (a) is incorrect

b.

(5x + 6 )2  = -4x - 9

Open brackets

10x + 12 = -4x -9Collect like terms10x + 4x = -12 -914x = -21x = -21/14

Option (b) is correct

(c.)

52x + 3 = 3 - (4x + 12)

Open brackets

52x + 3 = 3 - 4x - 1252x + 3 = -4x - 952x + 4x = -9 - 356x = - 12x = -12/56x = -3/14

Option (c) is incorrect

(d)

(5x + 6)2 = -4x + 15

Open brackets

10x + 12 = -4x + 1510x + 4x = -12 + 1514x = 3x = 3/14

Option (d) is incorrect

(e)

5x + 6 = -8x - 18

Collect like terms

5x + 8x = -18 - 613x = - 24x = -24/13

Option (e) is incorrect

Therefore, we can conclude that the correct equation equivalent to the given expression in the question can be seen in Option b.

What’s the value of X?

Answers

Answer:

x = -2

Step-by-step explanation:

Step 1: Write equation

2(x - 6) + 6 = 4x - 2

Step 2: Solve for x

Distribute 2: 2x - 12 + 6 = 4x - 2Combine like terms: 2x - 6 = 4x - 2Subtract 2x on both sides: -6 = 2x - 2Add 2 to both sides: -4 = 2xDivide both sides by 2: -2 = xRewrite: x = -2

Step 3: Check

Plug in x to verify it's a solution.

2(-2 - 6) + 6 = 4(-2) - 2

2(-8) + 6 = -8 - 2

-16 + 6 = -10

-10 = -10

Answer:

distribute the 2. add -12+6. add 2 to both sides. decide both sides by 2. x= -2

If a point (x,y) is rotated 90 degrees counterclockwise around the origin, what will the resulting coordinate be?

Answers

Answer:

Step-by-step explanation:

90 degrees clockwise will result in a (+,+) answer.

90 degrees counterclockwise will result in a (-,+) answer.

Think of your quadrants.

Quadrant 1 the answer will be (+,+)

Quadrant 2 the answer will be (-,+)

Quadrant 3 the answer will be (-,-)

Quadrant 4 the answer will be (+,-)

It all depends where you are starting, so if you have to go counter clockwise from the third quadrant, your answer will be a coordinate that is (+,-).

Answer:

[tex]x > 3[/tex]

Step-by-step explanation:

Luckily for our brains, inequalities work very similar to equations when solving. Let's get on it.

First, we need to subtract 3 from both sides to isolate the -4x (this means we can then divide to get x by itself).

Which leaves us with [tex]-4x<-12[/tex].

Now we need to divide both sides by -4. Here's the thing - with inequalities, when we divide both sides by a negative, the sign flips! So after doing this simplification, our inequality looks like this: [tex]x > 3[/tex]

Pour tout réel x, on pose : f(x) = -2x²+4x+6. Vérifier que (-1) est une racine de ce polynôme f. On sait que l'axe de symétrie de la parabole qui représente f est la droite d'équation : x=1. Déduire de cette information l'autre racine du polynôme f. Factoriser le polynôme f. Aidez-moi svp meci d'avance

Answers

Explication étape par étape:

Étant donné la fonction polynomiale f (x) = -2x² + 4x + 6. Pour vérifier si f (-1) est un facteur de l'expression, nous devons montrer que f (-1) est équivalent à zéro. S'il est nul, donc x + 1 est un facteur du polynôme.

Preuve

f (x) = -2x² + 4x + 6

f (-1) = -2 (-1) ² + 4 (-1) +6

f (-1) = -2 (1) -4 + 6

f (-1) = -2-4 + 6

f (-1) = -6 + 6

f (-1) = 0

Puisque f (-1) = 0, donc x + 1 est un facteur du polynôme.

Ensuite, il faut obtenir l'autre racine du polynôme. Pour obtenir cela, nous devons factoriser la fonction polynomiale donnée.

Soit f (x) = 0

-2x² + 4x + 6 = 0

multiplier par -1

2x²-4x-6 = 0

diviser par 2

x²-2x-3 = 0

x²-3x + x-3 = 0

x (x-3) +1 (x-3) = 0

(x + 1) (x-3) = 0

x + 1 = 0 et x-3 = 0

x = 1 et x = 3

Par conséquent, l'autre racine du polynôme en dehors de 1 est x = 3

A father is 30 years elder than his son. after 8 years he will be 4 times as old as his son. find their present ages

Answers

Given:

Father is 30 years older than the son.

After 8 years , he will be 4 times as old as his son.

Find:

their present ages

Solution:

Let the son's age be x and age of father be y years

⟹ Father's age = Son's age + 30

⟹ y = x + 30 -- equation (1)

Also,

Son's age after 8 years = (x + 8) years.

Father's age after 8 years = (y + 8) years.

According to the above condition,

⟹ y + 8 = 4(x + 8)

⟹ y + 8 = 4x + 32

Substitute the value of y from equation (1).

⟹ x + 30 + 8 - 32 = 4x

⟹ 6 = 4x - x

⟹ 6 = 3x

⟹ 6/3 = x

⟹ 2 = x

Substitute the value x in equation (1).

⟹ y = 2 + 30

⟹ y = 32

Therefore,

Son's present age = x = 2 years.

Father's present age = y = 30 years.

I hope it will help you.

Regards.

Answer:

→ 11(2 + y) + 11y

→ 22 + 11y + 11y = 154

→ 22y + 22 = 154

→ 22y = 154 - 22

→ 22y = 132

→ y = 132/22

→ y = 6
