Answer:
Se vendieron 124 boletos para adultos y 103 boletos para estudiantes.
Step-by-step explanation:
Un sistema de ecuaciones es un conjunto de ecuaciones con las mismas incógnitas. Un sistema de ecuaciones lineales es un sistema de ecuaciones en el que cada ecuación es lineal.
En otras palabras, un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.
Resolver un sistema de ecuaciones significa encontrar valores para las incógnitas que hace verdadera cada una de las ecuaciones.
En este caso, las variables son:
x: cantidad de boletos para adultos.y: cantidad de boletos para estudiantes.Los boletos para la obra de teatro "Los Miserables" cuestan 15 dólares para adultos y 5 dólares para estudiantes. Si se vendieron 227 boletos y los ingresos fueron de 2,375 dólares, se puede expresar el siguiente sistema de ecuaciones:
[tex]\left \{ {{x+y=227} \atop {15*x+5*y=2375}} \right.[/tex]
Se elige resolver por el método de sustitución, cuyo primer paso consiste escoger una ecuación y despejar una incógnita en términos de la otra incógnita. En este caso, se despeja la variable "y" de la primer ecuación, obteniendo:
y=227 - x
A continuación se sustituye la expresión hallada en la otra ecuación, para obtener una ecuación con una incógnita y, luego despejar esa incógnita. En este caso, reemplazando la anterior expresión en la segunda ecuación del sistema de ecuaciones:
15*x + 5*(227 -x)= 2375
Resolviendo:
15*x + 5*227 - 5*x= 2375
15*x + 1135 - 5*x= 2375
15*x - 5*x= 2375 - 1135
10*x= 1240
x= 1240 ÷10
x= 124
Finalmente se sustituye el valor hallado en la expresión y=227 - x para despejar la incógnita restante:
y=227 - 124
y= 103
Entonces se vendieron 124 boletos para adultos y 103 boletos para estudiantes.
Which expression is equivalent to5(h+9)
Answer:
The answer would be 5h+45
Step-by-step explanation
5 (h+9)
You need to convert this equation into the equation
you multiply 5 by h and get 5h
Then multiply the same number outside the parenthesis, 5, by 9 which will give you the answer 45
Once you have 5h and 45 just put it together with the addition symbol which will will equal:
5 (h+9) = 5h + 45

A certain computer loses half of itş value every two years.
If the value of the computer after 3 years is $425, what was the initial
value of the computer?
A. $601.04
B. $850.00
C. $1,202.08
D. $2,404.16
The initial value of the computer is 1,700.
What is the meaning of initial value?The initial value is the beginning output value.
We have given that the computer losses half of its value, and If the value of the computer after 3 years is 425,
we have to calculate, what was the initial value of the computer,
Suppose that the initial value of computer is x
So after two years it will be,
for the second year, it is X/2
for the third year, it is X/2
In the fourth year, it is X/4
we have given that after 3 years, the value of the computer is 425 Therefore we can write it as,
X/4=425
X=4(425)
X=1700
Therefore, the initial value of the computer is 1,700

The length of a rectangular table is two times its width. If the perimeter of
the table is 2,000 ft, set up an equation to find the width (w) of the table.
1. 2000 = 2(2W + W)
2. 1000 = 2(3W+ W)
3. 2000 = 2(2wx W)
4. 2000 = 2(3wx w)
Answer:
1. 2000 = 2(2W + W)
Step-by-step explanation:
perimeter = 2(L + W)
L = 2W, so:
perimeter = 2(2W + W)

Answer:
x = 13.3125
Step-by-step explanation:
Since it is a square, divide the area (225) by 4: 56.25
Now solve for x
56.25 - 3 = 53.25
53.25 / 4 = 13.3125
Please check if this is the method you need, and if I solved for the right thing!

6(2x2 – 5) = [?]
X=-3
Answer:
78
Step-by-step explanation:
Substitute x = - 3 into the expression
6(2(- 3)² - 5)
= 6(2(9) - 5)
= 6(18 - 5)
= 6(13)
= 78
Find the slope of the line through the given points.* (-13, 10), (10, -13)
===========================================
Work Shown:
Let's apply the slope formula to get...
m = (y2 - y1)/(x2 - x1)
m = (-13 - 10)/(10 - (-13))
m = (-13 - 10)/(10 + 13)
m = -23/23
m = -1
The slope is -1
-----------
Extra info:
The slope is the rate of change. Specifically it's the change in y over the change in x. So that's why we divide the (y2-y1) over the (x2-x1). The (y2-y1) is the change in y; the (x2-x1) is the change in x.
You can think of it as
slope = rise/run
rise = y2-y1 = change in y
run = x2-x1 = change in x
Name a positive angle between 0 radians and 2π radians that is coterminal with an angle in standard position whose measure is −3π2 radians.
Answer:
The positive angle between [tex]0[/tex] and [tex]2\pi[/tex] radians that is coterminal with [tex]\theta = -\frac{3\pi}{2}\,rad[/tex] is [tex]\theta = \frac{\pi}{2}\,rad[/tex].
Step-by-step explanation:
GIven that the measure of the known angle is [tex]-\frac{3\pi}{2}[/tex] radians and that such angle belongs to a set of angles in terms of revolutions (with a period of [tex]2\pi[/tex]) done either clockwise or counterclockwise, we can represent the family of coterminal angles with the following expression:
[tex]\theta = -\frac{3\pi}{2}\pm (2\pi\cdot i)[/tex], for [tex]i \in \mathbb{N}_{O}[/tex] (1)
Where [tex]i[/tex] is the index of the coterminal angle.
According to the statement, we must name a positive angle between [tex]0[/tex] and [tex]2\pi[/tex] radians, which can be found by the sign [tex]+[/tex] and [tex]i = 1[/tex]. Hence, we find the required angle:
[tex]\theta = -\frac{3\pi}{2} + 2\pi[/tex]
[tex]\theta = \frac{\pi}{2}\,rad[/tex]
The positive angle between [tex]0[/tex] and [tex]2\pi[/tex] radians that is coterminal with [tex]\theta = -\frac{3\pi}{2}\,rad[/tex] is [tex]\theta = \frac{\pi}{2}\,rad[/tex].

Answer:
what she sells each t-shirt for.
Step-by-step explanation:
if f(x) is the profit and x=# of t-shirts,
the rate of change is 8, which is what she sells each t-shirt for.
The 100 that is subtracted, is the money that she spent on materials.
For eg, if she sells 8 t-shirts she makes $64, but she spent $100 before and didn't gain any profit, having not made up $36 from what her original spending was.

Answer:
its the one thats right
Step-by-step explanation:
help me with this math question please I'm giving away brainliests
Answer:
Step-by-step explanation:
Given function is,
[tex]f(x)=\frac{2x^2+6x}{-4x^2+8x}[/tex]
[tex]=\frac{2x(x+3)}{-4x(x-2)}[/tex]
This function is not defined at "x(x - 2) = 0"
Therefore, for the values of x = 0 and 2, given function is not defined.
Vertical asymptote → x = 2 [Denominator = 0]
For Horizontal asymptote → [tex][\frac{2x^2}{-4x^2} =-\frac{1}{2}][/tex]
Therefore, horizontal asymptote → y = [tex]-\frac{1}{2}[/tex]
x-intercept,
For f(x) = 0,
Numerator of the function = 0
2x² + 6x = 0
2x(x + 3) = 0
x = -3
Therefore, x - intercept → (-3, 0)
For y-intercept,
x = 0
f(0) = 0
Therefore, graph has no y-intercept.
For holes on the graph,
Since, function is not defined at x = 0,
f(x) = [tex]\frac{(x+3)}{-2(x-2)}[/tex]
f(0) = [tex]\frac{(0+3)}{-2(0-2)}[/tex]
= [tex]\frac{3}{4}[/tex]
Therefore, hole on the graph → [tex](0, \frac{3}{4})[/tex]
