Answer:
17 is your answer
Step-by-step explanation:
Given a peicewise function, with two parts:
{f(x) = 4x+3 {if x<2}
f(x) = 5x+2 {if x>2}
f(3) = f(x) when x is 3, 3 > 2, 3 is not less than 2 so f(x) for x>2 is 5x + 2.
Therefore f(3) = 5(3) + 2 = 15 + 2 = 17

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

On the real number line, the midpoint of —3 and 11 will be 4.
What does a midpoint mean?Midpoint, as the word suggests, means the point which lies in the middle of something.
Midpoint of a line segment means a point which lies in the mid of the given line segment.
The coordinates of midpoint of the line segment AB are;
Suppose we've two endpoints of a line segment as:
A(p,q), and B(m,n)
Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:
[tex]x = \dfrac{p+m}{2}[/tex]
and
[tex]y = \dfrac{q+n}{2}[/tex]
Hence, On the real number line, the midpoint of —3 and 11 will be 4.

Answer:
(B)
b + t = 15
2b + 3t = 45
Step-by-step explanation:
Bicycles and tricycles are represented by the letters b and t respectively.
total no of bicycles and tricycles = 15
So,
b + t = 15
Each bicycle has 2 wheels and each tricycle has three wheels.
So,
No of wheels in b bicycles = 2b
No of wheels in t tricycles = 3t
Total no of wheels = 45
So,
2b + 3t = 45

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].

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]

The cost to mail a package is $7 for the first 2 pounds and 30 cents for each additional ounce.
Which of the following functions represents the cost to mail a package if x is the number of ounces over 2 pounds?
ƒ(x ) = 7 + 0.3x
ƒ(x ) = 14 + 0.3x
ƒ(x ) = 0.3(x + 2)
Answer:
the first one
Step-by-step explanation:
The cost to mail a 2-lb package is $7.
The cost to mail a 2-lb, 1 oz package is $7+$0.30(1).
That to mail a 2-lb, 2 oz package is $7+$0.30(2) = $7.60.
Following this pattern, the general formula is f(x) = $7 + $0.30x, where x represents the number of ounces OVER 2 lb.

what is the solution of this system of Linear equations? y=3×-2 and y-2=×
Answer:
(2, 4)
Step-by-step explanation:
Given the system of equations
y=3×-2.... 1
y-2=× ... 2
Substitute 2 into 1
y = 3(y-2) - 2
y = 3y - 6 - 2
y - 3y =-6-2
-2y = -8
y = -8/-2
y = 4
Recall that
x = y - 2
x = 4-2
x = 2
Hence the solution (x, y) is (2,4)
