We have the following function:
(x)  = 3x - 7
The function f translated 6 units up and 2 units rigth:
6 units up:
y  = 3x - 7 + 6
2 units rigth:
y  = 3(x-2) - 7 + 6
y  = 3x - 6 - 7 + 6
Finally:
g(x)  = 3x - 7

The function f reflected about the y-axis and translated 7 units left:
reflected about the y-axis:
y = 3(-x) - 7
y = -3x - 7
translated 7 units left:
y = -3(x+7) - 7
y = -3x - 21 - 7
y = -3x -28
Finally:
g(x) = -3x - 28

The function f stretched vertically by a factor of 2 and translated up by 5 units:
stretched vertically by a factor:
y = 6x - 14
translated up by 5 units: 
y = 6x - 14 + 5 
y = 6x - 9
Finally:
g(x) = 6x - 9

 The function f stretched vertically by a factor of 4 and translated up by 9 units:
stretched vertically by a factor of 4:
y = 12x - 28
translated up by 9 units: 
y = 12x - 28 + 9 
y = 12x - 19
Finally:
g(x) = 12x - 19

Given that our original function is:
f(x)=3x-7

To Match each verbal description to its equivalent function rule we shall proceed as follows:
The function is translated 6 units up and 2 units right. 
since f(x) cuts through point (0,-7) the translation will give us the points (2,-7) and (2,-1), since the new line is parallel to the old, the slope will be m=3, thus the equation will be:
y=3x+c
using point (2,-1)
-1=3(2)+c
-1-6=c
c=-7
thus our equation will be:
y=3x-7
thus our new equation is: g(x)=3x-7


b] The function f is reflected about the y-axis and translated 7 units left. when we reflect the function f o y -axis, the new function will be:
y=-3x-7
when we translate this 7 units to the left we shall have:
y=-3x(x+7)-7
thus the final equation is
g(x)=-3x-21-7
simplifying we obtain:
g(x)=-3x-28


c] When f is stretched vertically by a factor of 2 and translated up by 5 units we shall have the following:
when f is stretched, the new function will be:
y=2(3x-7)
y=6x-14
when the above function is translated up by 5 units we shall have:
y=6x-14+5
thus simplifying the above the function becomes
g(x)=6x-9

c] The factor f is stretched vertically by a factor of 4 and translated up by 9 units.
when f(x) is stretched by a factor of 4, the new function will be:
f(x)=4(3x-7)
f(x)=12x-28
when the function is translated up by 9 units, the new function will be:
f(x)=12x-28+9
simplifying the above we get:
g(x)=12x-19

en una encuesta a 200niños sobre el programa de T.V. que más les gusta ver ,se encontró que a 30 niños ven dibujos animados 45 n
Lelu [443]

Answer:

15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Step-by-step explanation:

Dado que en una encuesta a 200 niños sobre el programa de TV que más les gusta ver se encontró que 30 niños ven dibujos animados, 45 niños miran películas animadas, 55 niños miran programas sobre animales, 38 niños miran programas sobre animales y dibujos animados y 32 niños miran los tres tipos de programas, para determinar el porcentaje de cada grupo​ se deben realizar los siguientes cálculos:

30/200 = 15/100 = 15%

45/200 = 22.5/100 = 22.5%

55/200 = 27.5/100 = 27.5%

38/200 = 19/100 = 19%

32/200 = 16/100 = 16%

Así, 15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.
