Answer:
3 > -7
Step-by-step explanation:
-9 < 21
/-3 /-3
------------
3 < -7
Now, whenever you divide or multiply by a negative, you will change the inequality sign.
So, 3 < -7 becomes 3 > -7
Answer:
3 > -7
Step-by-step explanation:
-9/ -3 = 3
21/ -3 = -7
3 = -7
3 > -7

Answer:
7 hours
Step-by-step explanation:
If it's $12 + $5(h) = 47, take away 12 automatically as this value doesn't depend on the hours. 47-12 is 35 so divide by 5 to get the hours. 35/5 is 7 so he rode 7 hours.

Answer:
To convert fahrenheit to celsius subtract 32 from the fahrenheit number and then multiply it by 5/9!!
1. a. about -17.78 degrees celsius
work: 0-32 = -32 times 5/9
-32*5 = -160
-160/9 = about -17.78
b. 0 degrees celsius
work: 32-32 = 0
0*5/9 = 0
c. about 21.11 degrees celsius
work: 70-32 = 38
38*5/9 = about 21.11
d. 37 degrees celsius
work: 98.6-32 = 66.6
66.6*5/9 = 37
e. about 37.78 degrees celsius
work: 100-32 = 68
68*5/9 = about 37.78
f. 100 degrees celsius
work: 212-32 = 180
180*5/9 = 100
celsius to fahrenheit is that number times 9/5, then + 32
2. (all of these answers are in degrees FAHRENheit. Make sure to write that!)
a. 32
work: 0*9/5 = 0 and 0+32 = 32
b. 89.6
work: 32*9/5 = 57.6.
57.6+32 = 89.6
c. 158
work: 70*9/5 = 126. 126+32 is 158
d. 209.48
work: 98.6*9/5 = 177.48. 177.48+ 32= 209.48
e. 212
work: 100*9/5 = 180. 180 + 32 = 212
f. 413.6
212*9/5 = 381.6. 381.6+32 = 413.6

The answer should be 2, 4.
Andres tiene una tienda donde venden juguetes de colección, entre ellos las esferas del dragón, cada esfera viene en una caja de forma cúbica cuya arista mide (a + 2) cm Andres hace un pedido de cierta cantidad de estas esferas, estas son colocadas en una caja cuya base tiene un área de (25a2 + 100a +100)cm2 y una altura de (3a + 6)cm.
A. ¿Cuál es el volumen de una caja que contiene una esfera del dragón y la caja donde se ubicará el pedido? Representa algebraicamente de dos formas.
B. ¿Cuántas cajas con las esferas del dragón compró Andres, si se sabe qué la caja donde se colocará el pedido se llena totalmente? Representa esta situación mediante una fracción algebraica y reducela de ser posible Si el valor de "a" fuera 6 ¿cambiaría la cantidad de cajas con esferas del dragón pedidas por Andres? justifica tu respuesta
Un reto más: La cantidad de niveles que tendrá la caja donde se colocará el pedido se puede representar con la siguiente expresión:
[tex] \frac{3a + 6}{a + 2} [/tex]
Tenemos un problema sobre volumenes y factorización.
Partimos con la informacion:
Cada caja de esfera es una cúbica, y tiene una arista que mide (a + 2)cm
Sabemos que la caja que contiene las cajas de las esferas tiene:
una base:
B = (25*a^2 + 100*a +100)cm^2
una altura:
H = (3a + 6)cm
A) Queremos encontrar el volumen de ambas cajas.
Sabemos que para un cubo, el volumen es el cubo de la arista, entonces el volumen de la caja que contiene la esfera es:
V = cm^3 = (a^3 + 6*a^2 + 12*a + 8) cm^3
(expresado en forma factorizada y expandida)
Y para un prisma rectangular, el volumen será igual que el producto entre la base y la altura.
V' = B*H = [(25*a^2 + 100*a +100)cm^2]*[(3a + 6)cm]
Tambien podemos expandir esto a:
V' = (75*a^3 + 450*a^2 + 900*a + 600) cm^3
También expresado en dos formas.
B) Para responder esto debemos tomar el cociente V'/V
[tex]V'/V = \frac{(75*a^3 + 450*a^2 + 900*a + 600) cm^3}{(a^3 + 6*a^2 + 12*a + 8) cm^3}[/tex]
Para simplificar esto, deberíamos utilizar las formas factorizadas:
[tex]V'/V = \frac{ [(25*a^2 + 100*a +100)]*[(3a + 6)]}{ (a + 2)^3} = \frac{ 3*[(25*a^2 + 100*a +100)]*[(a + 2)]}{ (a + 2)^3} \\\\V'/V = \frac{ 3*[(25*a^2 + 100*a +100)]}{ (a + 2)^2}[/tex]
Ahora debemos factorizar la base:
25*a^2 + 100*a + 100
Para ello debemos encontrar las dos raices, que se obtienen con:
[tex]a = \frac{-100 \pm \sqrt{100^2 - 4*25*100} }{2*25} = \frac{-100 \pm 0 }{25*2} = -2[/tex]
(dos raices iguales a -2)
Entonces podemos escribir:
25*a^2 + 100*a + 100 = 25*(a + 2)^2
Remplazando esto en el cociente de volumenes, obtenemos:
[tex]V'/V = \frac{ 3*[(25*a^2 + 100*a +100)]}{ (a + 2)^2} = \frac{3*25*(a + 2)^2}{(a + 2)^2} = 3*25 = 75[/tex]
Asi, podemos ver que entran 75 cajas.
También se pregunta:
" Si el valor de "a" fuera 6 ¿cambiaría la cantidad de cajas con esferas del dragón pedidas por Andres? "
La respuesta es no, pues podemos ver que el cociente de volumenes no depende del valor de a.
Reto extra:
La cantidad de niveles está dada por:
[tex]\frac{3a + 6}{a + 2} = \frac{3(a + 2)}{a + 2} = 3[/tex]
Así podemos ver que hay 3 niveles.

2. Which of the following inequalities is NOT true? F 0.309 > 0.3 G 0.329 > 0.4 H 0.104 > 0.09 J 0.9 > 0.890
Answer:
I believe that G 0.329 > 0.4 is not true.
Step-by-step explanation:
0.4 is clearly a larger number than 0.329. I feel like the key point to these are the starting numbers behind the decimal. So for 0.329 the key number would be the 3, and for 0.4 the key number would be the 4. Now which one do you think is bigger? Obviously the 0.4 for G is NOT true.

The following points are on the graph of a function:
X Y
2 4
3 5
4 6
5 7
6 8
7 9
Which point would be on the inverse of this function?
A (7, 5)
B (-7, -5)
C (-5, -7)
D (-2, -4)
An inverse function reverses the roles of inputs and outputs (of x-values and y-values).
If (2,4) is on the graph of a function, then (4,2) is on the graph of the inverse function.
If (9,7) is on the graph of the inverse, then (7,9) would be on the graph of the original function.
If (a,b) is on the graph of the function, then (b,a) is on the graph of the inverse.
Getting to your question, which of the points listed has the inverse listed up in the table?

Answer:
Here both line are perpendicular because as product of slope of both lines is -1
Answer:
lines are perpendicular
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(1)
y = [tex]\frac{3}{4}[/tex] x - 1 ← is in slope- intercept form
with slope m = [tex]\frac{3}{4}[/tex]
(2)
3y = - 4x + 6 ( divide each term by 3 )
y = - [tex]\frac{4}{3}[/tex] x + 2 ← in slope- intercept form
with slope m = - [tex]\frac{4}{3}[/tex]
Then
[tex]\frac{3}{4}[/tex] × - [tex]\frac{4}{3}[/tex] = - 1
Thus the 2 lines are perpendicular to each other
