Step-by-step explanation:
y = -2x + 1. => Slope = -2
Then the perpendicular line will have a slope of -1/(-2) = 0.5.
We have y = 0.5x + c.
When x = 4, y = -3.
=> (-3) = 0.5(4) + c, c = -5.
Hence the answer is y = 0.5x - 5. (C)

A pension fund owns 11,000 shares in a stock mutual fund and a bond mutual fund. Currently the stock fund sells for $12 per share and the bond sells fund sells for $15 per share. How many shares of each does the pension fund own if the value of the securities is $150,000?
Fund owns:
Stock fund shares
Bond fund shares
9514 1404 393
Answer:
5000 shares of stock fund6000 shares of bond fundStep-by-step explanation:
Let b represent the number of shares of the bond fund owned. Then the value of the pension fund is ...
15b +12(11000-b) = 150000
3b = 18000 . . . . . . . . . . subtract 130,000
b = 6000 . . . . . . . . . shares of bond fund
11000 -b = 5000 . . . shares of stock fund

An isosceles triangle has a perimeter of 28.12 centimeters. The length of the longest side is 13.08 centimeters. What could be the length of
one of the other sides of the triangle?
A. 3.92 centimeters
B. 7.52 centimeters
C. 11.26 centimeters
D. 15.04 centimeters
Answer:
7.52 cm
Step-by-step explanation:
If we subtract the longest side from the whole perimeter, we get 28.12 - 13.08 = 15.04.
So the other two sides must be equal, since the triangle is isosceles.
That means 15.04 must be divided evenly betweem two sides.
15.04/2 = 7.52
So the 3 sides are 13.08 cm, 7.52 cm, and 7.52 cm.
You check the answer by adding all 3 sides together and we do indeed get the perimeter, 28.12 cm.

simplify the ratio 3 hours 1 hour 20 minutes
Answer:
9 : 4
Step-by-step explanation:
3 hours = 3*60 = 180 minutes
1 hour 20 min = 1*60 + 20 = 80 minutes
[tex] \frac{180}{80} = \frac{18}{8} = \frac{9}{4} = 9 : 4[/tex]
We are required to simplify the ratio 3 hours 1 hour 20 minutes
The simplest ratio of 3 hours : 1 hour : 20 minutes is 9 : 3 : 1
Convert hour to minutes
1 hour = 60 minutes
3 hours = 60 minutes × 3
= 180 minutes
1 hour = 60 minutes
So,
3 hours : 1 hour : 20 minutes
= 180 minutes : 60 minutes : 20 minutes
= 18 : 6 : 2
= 9 : 3 : 1
Therefore, the simplest ratio of 3 hours : 1 hour : 20 minutes is 9 : 3 : 1

-3(x - 1) + 9 = 15 find the varible
Answer:
x = -1
Step-by-step explanation:
-3(x-1) + 9 = 15
-3x + 3 + 9 = 15
-3x = 3
x = -1
Answer:
The variable (x) is -1.
Step-by-step explanation:
use the distributive property
-3(x - 1) + 9 = 15
-3x + 3 + 9 = 15
-3x + 12 = 15
-12 -12
-3x = 3
divide by -3
x = -1
Determine the domain and range of the graphed function.
A) domain: (-∞, ∞) range: (-∞, 10)
B) domain: (-∞, ∞) range: (-∞, 10]
C) domain: (-∞, 10) range: (-∞, ∞)
D) domain: (-∞, 10] range: (-∞, ∞)
Answer:
B
Step-by-step explanation:
We assume the function goes infinitely both "left" and "right" so the domain is (-inf, inf).
We can also see that it has a maximum in (0, 10), so it takes all the values from -inf to 10 exactly. If it never reached 10, it'd be (-inf, 10) but it does, so it's (-inf, 10].

5n+1/n+3
Answer:
5(n+1)/((n+1)(n+3))
5/(n+3) is a answer
Step-by-step explanation:
(n+1)/(n+1)=1
The solution is, the simplified product of the expression 5/n+1*n+1/n+3 is 5/(n+3) .
here, we have,
given that,
the expression is 5/n+1*n+1/n+3
now, we have to find the simplified product.
as, * means the multiplication,
we get,
5/n+1*n+1/n+3
=5*(n+1)/((n+1)*(n+3))
now, we know that,
(n+1)/(n+1)=1
so, we get,
5*(n+1)/((n+1)*(n+3))
=5*1 /(n+3) *1
=5/(n+3) is a answer

Lugar geométrico infinito formado por un conjunto de puntos que conservan la misma dirección
Answer:
l lugar geométrico de los puntos que equidistan a otros dos puntos fijos {\displaystyle A}A y {\displaystyle B}B es una recta o eje de simetría de dichos dos puntos. Si los dos puntos son los dos extremos de un segmento {\displaystyle {\overline {AB}}}\overline {AB}, dicha recta, o lugar geométrico, es llamada mediatriz y es la recta que interseca perpendicularmente a {\displaystyle {\overline {AB}}}\overline {AB} en su punto medio.
La bisectriz cumple la propiedad de que todos sus puntos equidistan a los lados de dicho ángulo, convirtiéndose la bisectriz en un caso particular del lugar geométrico que sigue a continuación.
El caso de equidistancia a dos rectas paralelas, obtenemos que la paralela media es el lugar geométrico de los puntos que las equidistan. Se observa que, bajo el punto de vista de que las rectas paralelas se cortan en el infinito -se elimina, pues, la noción de paralelismo-, pasa a ser un sinónimo de la bisectriz, donde el ángulo ha tomado valor nulo.
Secciones cónicas
Las secciones cónicas pueden ser descritas mediante sus lugares de geométria:
La circunferencia es el lugar geométrico de los puntos cuya distancia a un punto determinado, el centro, es un valor dado (el radio).
La elipse es el lugar geométrico de los puntos tales que la suma de su distancia a dos puntos fijos, los focos, es una constante equivalente a la longitud del eje mayor de la elipse.
La parábola es el lugar geométrico de los puntos cuya distancia a un foco equivale a su distancia a una recta llamada directriz.
La hipérbola es el lugar geométrico de los puntos tales que el valor absoluto de la diferencia entre sus distancias a dos puntos fijos, los focos, es igual a una constante (positiva), que equivale a la distancia entre los vértices.
Una recta es un lugar geométrico infinito formado por un conjunto de puntos que conservan la misma dirección.
Descripción de un enunciado de un lugar geométrico dado
En este ejercicio debemos concluir que tipo de expresión se deriva del enunciado del lugar geométrico. Recuérdese que un lugar geométrico es un conjunto de puntos que satisfacen una característica dada.
Matemáticamente hablando, el lugar geométrico puede ser definido a partir de las definiciones de longitudes de segmento de recta:
[tex]AC = AB + BC[/tex] (1)
Puesto que [tex]AB[/tex] y [tex]BC[/tex] tienen la misma dirección, entonces es posible aplicar las siguientes equivalencias:
[tex]BC = k \cdot AB[/tex], [tex]k\in \mathbb{R}[/tex] (2)
[tex]AC = r\cdot AB, \,r\in\mathbb{R}[/tex] (3)
Al aplicarse (2) y (3) en (1) y simplificar la expresión, tenemos lo siguiente:
[tex]r = 1 + k[/tex] (4)
Por geometría analítica tenemos que el lugar geométrico debe ser una recta, puesto que [tex]r[/tex] y [tex]k[/tex] representan un conjunto infinito de elementos. [tex]\blacksquare[/tex]
