Write a function for the graph of y=3x+7 after the slope is doubled.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]y=3x+7[/tex]
As we know that the slope-intercept of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so comparing the equation [tex]y=3x+7[/tex] with the slope-intercept of the line equation, we conclude that
[tex]y = 3x+7[/tex]
[tex]m = 3[/tex]
So, the slope of the line is [tex]m = 3[/tex]
As the function is
[tex]y = 3x+7[/tex]
Now, if we double the slope,
The slope will become: 2m = 2(3) = 6
Therefore, the function of the graph after doubling the slope will become:
[tex]y = 6x+7[/tex]

gave her the right advice for how to fix it. What advice did Jennifer give to Ruby?
O
Multiply both sides of the equation by 3. The standard form of the equation is 12x - 2y = 21.

Jennifer told Ruby her equation is already in standard form and there is nothing to correct.
Oc
Multiply both sides of the equation by 3. The standard form of the equation is 12x - 2y = 7
Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x - y = 10.5.

1-La funcion lineal que pasa por el punto (3,6) tiene como expresion:
a) Y=3x+6
b) Y=6x-3
c) Y=2x
Answers
Answer:
Creo que es b
Step-by-step explanation:
The linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]
How to know if a point lies in the graph of a function?All the points (and only those points) which lie on the graph of the function satisfy its equation.
Thus, if a point lies on the graph of a function, then it must also satisfy the function.
Checking all the options to see if (3,6) lies on them:
Case 1: [tex]y = 3x + 6[/tex]Usually points are of the form (x,y). Thus, we have: (x,y) = (3,6) means x = 3, and y = 6.
Putting these values in the equation, we get:
[tex]y = 3x + 6\\6 = 3(3) + 6\\6 = 9 + 6\\6 = 15[/tex]
This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.
Case 2: [tex]y = 6x - 3[/tex]Putting x = 3, y = 6 in this equation, we get:
[tex]y = 6x - 3\\6 = 6(3) - 3\\6 = 18 - 3 \\6 = 12[/tex]
This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.
Case 3: [tex]y = 2x[/tex]Putting x = 3, y = 6 in this equation, we get:
[tex]y = 2x\\6 = 3(2)\\6 = 6[/tex]
This is correct. Thus, the point (3,6) satisfy this equation, and therefore, lies on its graph.
Thus, the linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]

parallel lines A B and C D are cut by a transversal forming 8 angles labeled 1 to 8. The transversal intersecting line A B form angles 1, 2, 3, and 4 clockwise from top left. The transversal intersecting line C D form angles 5, 6, 7, 8 clockwise starting from top left.
Answers
Answer:
m∠8 = 30°
Step-by-step explanation:
Since line AB is parallel to line CD, and m∠4 = 30°, therefore:
m∠4 and m∠8 are corresponding angles.corewslinding angles are congruent.
Therefore, this means that their measure would be equal to each other, since they are congruent.
Thus:
m∠8 = 30°

C is the midpoint of segment AB D is the midpoint of segment BC A is located at (4,8) and B is located at (-12,4) what are the coordinates of D
Answers
Answer:
coordinates of D are ( -8, 5)
Step-by-step explanation:
- the formula of the coordinates of the midpoint is (x1+x2)/2 & (y1+y2)/2
- first we find midpoint C by using coordinates of points A and B
C => (4 - 12)/2 & (8 + 4)/2
calculate, coordinates of C are ( -4, 6 )
- now find midpoint D by using the coordinates of B and C
D => ( -12 - 4 )/2 & (4 +6)/2
calculate and the coordinates of D are ( -8, 5 )

En la sala de una casa hay una gran ventana de vidrio, por la que se presenta una pérdida significativa de calor; las medidas de la ventana son 2,5 m x 1,5 m y 2,8 mm de espesor. Hallar la variación de calor en la unidad de tiempo si la temperatura exterior del vidrio es 16°C y la temperatura interior del vidrio es 20°C
Answers
Answer:
La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.
Step-by-step explanation:
Asumamos que la transferencia de calor es enteramente por conducción, en estado estable y unidimensional´y que la ventana es representada por una placa plana. Bajo estas consideraciones, la ecuación de conducción es la siguiente:
[tex]\dot Q = \frac{k\cdot w\cdot h}{l}\cdot (T_{i}-T_{o})[/tex] (1)
Donde:
[tex]\dot Q[/tex] - Tasa de transferencia de calor, medida en watts.
[tex]k[/tex] - Conductividad térmica, medida en watts por metro-grado Celsius.
[tex]w[/tex] - Ancho de la ventana de vidrio, medido en metros.
[tex]h[/tex] - Altura de la ventana de vidrio, medida en metros.
[tex]l[/tex] - Espesor de la ventana de vidrio, medida en metros.
[tex]T_{i}[/tex] - Temperatura interior del vidrio, medida en grados Celsius.
[tex]T_{o}[/tex] - Temperatura exterior del vidrio, medida en grados Celsius.
Si conocemos que [tex]k = 0.8\,\frac{W}{m\cdot ^{\circ}C}[/tex], [tex]w = 2.5\,m[/tex], [tex]h = 1.5\,m[/tex], [tex]l = 2.8\times 10^{-3}\,m[/tex], [tex]T_{o} = 16\,^{\circ}C[/tex] y [tex]T_{i} = 20\,^{\circ}C[/tex], entonces la tasa de transferencia de calor es:
[tex]\dot Q = \left[\frac{\left(0.8\,\frac{W}{m\cdot ^{\circ}C} \right)\cdot (2.5\,m)\cdot (1.5\,m)}{2.8\times 10^{-3}\,m} \right]\cdot (20\,^{\circ}C-16\,^{\circ}C)[/tex]
[tex]\dot Q = 4285.714\,W[/tex]
La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.
