Answer: x + 16y
Step-by-step explanation:
multiply 4 to x+ 2y
4x + 8y - 3x + 8y (open the bracket)
x + 16y
Answer:
x+16y
Step-by-step explanation:
4(x+2y)-(3x-8y)
we open the brackets and the sign of the second bracket changes
4x+8y-3x+8y
we group x's and y's
x+16y

Step-by-step explanation:
The ordered pair (1, -2) is a solution to the system of linear equations.
2x + y = 0
-x + 2y = 5
True
False
Answer:
False
Step-by-step explanation:
2x + y = 0
Try (1, -2)
2(1) + (-2) = 0
2 + (-2) = 0
0 = 0
The solution works on the first equation.
-x + 2y = 5
-(1) + 2(-2) = 5
-1 - 4 = 5
-5 = 5
The solution does not work in the second equation.
Answer: False

What is my perfect crime? I break into Tiffany's at midnight. Do I go for the vault? No, I go for the chandelier. It's priceless. As I'm taking it down, a woman catches me. She tells me to stop. It's her father's business. She's Tiffany. I say no. We make love all night. In the morning, the cops come and I escape in one of their uniforms. I tell her to meet me in Mexico, but I go to Canada. I don't trust her. Besides, I like the cold. Thirty years later, I get a postcard. I have a son and he's the chief of police. This is where the story gets interesting. I tell Tiffany to meet me in Paris by the Trocadero. She's been waiting for me all these years. She's never taken another lover. I don't care. I don't show up. I go to Berlin. That's where I stashed the chandelier.
Please help me thank you

12. What is the slope of line with the points (2,2) and (1,5)?
Answer:
- 3Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
From the question we have
[tex]m = \frac{5 - 2}{1 - 2} = - \frac{3}{1} = - 3 \\ [/tex]
We have the final answer as

Which of the following is equal to 3.TE?
Determine the value of x and y
Answer:
x=65, y=60
Step-by-step explanation:
x=65--->corrosponding angles with the triangle
x+y+55=180--->linear pair
(65)+y+55=180
y=60
Answer:
x=65 y=60
Step-by-step explanation:
Well, divide the hypotenuse between two triangles added onto the square root of the divisions between Mars and Pluto and we can derive the positive neutrons of the seventeenth quadratic of the Einstein constant equation.
or, know that x=65 due to it being on a parallel line to it, then due to their being 360 degrees around a point, 65+65+55+55=240, 360-240=120, then divide that by two to get it at y.

Before attending a basketball course, a player found that 60% of his shots made a
score. After attending the course, the player claimed he had improved. In his next
game he tried 12 shots and scored in 10 of them. Assuming shots to be
independent, test his claim at the 10% level of significance
Answer:
Step-by-step explanation:
60% = 7.2/12
83% = 10/12
He improved by a supposed 23%
A bracelet costs $39.59. It is marked down 25%.
What is the final price of the bracelet after it is marked down?
$9.90
$29.69
$35.49
$49.49
Answer:
$29.69
Step-by-step explanation:
Marked down 25% means it is now worth 75% of original value.
0.75*39.59 = $29.69
please give thanks by clicking the heart buton :) happy holidays
Answer:
$29.70
Step-by-step explanation:
$39.59 / 4 = 9.8975. Round up to 9.90
$39.59 - $9.90 = $29.69
Which one of these formulas describes the following sequence?
1,5,12,22,35
We can find a formula for nth term of the given sequence as follows:
1, 5, 12, 22, 35
The 1st differences between terms:
4, 7, 10, 13
The 2nd differences :
3, 3, 3
Since it takes two rounds of differences to arrive at a constant difference between terms, the nth term will be a 2nd degree polynomial of the form: [tex]a n^2 + b n + c[/tex], where c is a constant. The coefficients a, b, and the constant c can be found.
We can form the following 3 equations with 3 unknowns a, b, c:
[tex]1 = a\cdot1^2 + b\cdot1 + c\\5 = \cdot2^2 + b\cdot2 + c\\12 = a\cdot3^2 + b\cdot3 + c[/tex]
Solving for a, b, c, we get:
a = 3/2, b = -1/2, c = 0
Therefore, the nth term of the given sequence is:
[tex]\boxed{ a_n = \dfrac{3}{2}n^2- \dfrac{1}{2} n}[/tex]

El tripe de a edad de pedro mas 2 es igual a la edad actual de pedro mas 6. ¿Cuál es la edad actual de pedro?
Answer: Pedro tiene 2 años.
Step-by-step explanation:
Definamos la variable P como la edad de Pedro.
Sabemos que " El triple de la edad de pedro, más 2, es igual a la edad actual de pedro más 6"
Esto se escribe como:
3*P + 2 = P + 6.
Para encontrar la edad de Pedro, tenemos que resolver esa ecuación.
Para hacerlo, el primer paso es llevar todos los términos con "P" al lado izquierdo, y los términos sin "P" al lado derecho.
3*P - P = 6 - 2
2*P = 4
Ahora podemos dividir por 2 en ambos lados:
2*P/2 = 4/2
P = 2
Entonces podemos concluir que Pedro tiene 2 años.
