Answer:
Triangle ABC is not a right triangle because d) it doesn't have a pair of perpendicular sides
Step-by-step explanation:
Perpendicular sides mean that the slopes are "opposite reciprocals" of each other.
Example: slope is 1/2 and the perpendicular line's slope is -2
How? 1/2 changes to 2 (you flip it, reciprocal), and then from 2 to -2 (apply opposite sign)
So when you calculate the slopes of AB, AC, and BC, none of their slopes are opposite reciprocals of each other. You can calculate the slopes of each and compare them if you want to check.
I really hope this helps, do you think you can tell me if you got the answer correct? I'd feel really bad if you got it wrong because of me. All I know is that it's not a right triangle.

Step-by-step explanation:
If a point (x,y) is rotated 90 degrees counterclockwise around the origin, what will the resulting coordinate be?
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 (+,-).
I wish you would have shared more information, but I hope this helps.

Solve: - 4x +3<-9
idk tbh
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]
And there's your answer. :)

Answer:
No Solution
Step-by-step explanation:

-10x-5>-5-10x
(Add 5 to both sides)
-10>-10x
(Add 10x to both sides)
-10x+10x>-10x+10x
Therefore , this equation has no solutions.

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
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

2(x - 6) + 6 = 4x - 2
What’s the value of X?
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 = -2Step 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
With the equation 3z + 3 = 22 + 6, the value of z is
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
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
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
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.
