What is y-13x=9 and how did you solve it

Mathematics
1 answer:
AURORKA [14]3 years ago
4 0

Simplifying

y + -13x = 9

Reorder the terms:

-13x + y = 9

Solving

-13x + y = 9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

-13x + y + -1y = 9 + -1y

Combine like terms: y + -1y = 0

-13x + 0 = 9 + -1y

-13x = 9 + -1y

Divide each side by '-13'.

x = -0.6923076923 + 0.07692307692y

Simplifying

x = -0.6923076923 + 0.07692307692y

Mazyrski [523]

Answer:

a) The rate of change is 3.5

b) The rate of change represents the price of a single cookie. $3.5

Step-by-step explanation:

a) To determine the rate of change along the graph, select a pair on the graph as;

(2,7)  and (8,28)

Rate of change, m= change in y/change in x

m=28-7/8-2 = 21/6 =7/2 = 3.5

b)

The equation of the relationship can be written as;

y=3.5 x + 0  where y is the amount collected and x is the number of cookies sold.

The slope here represents the price per cookie in $, $3.5

En un día de temporal de lluvia el meteorólogo dijo en las noticias que la probabilidad de que lloviera ese día era del 70%. ¿Qu
drek231 [11]

Answer:

Vamos a definir:

100% probabilidad de lluvia = Es seguro que ese día va a llover.

0% probabilidad de lluvia = Es seguro que ese día no va a llover.

Ahora, los valores intermedios admiten una dualidad, es decir, es posible que llueva o que no.

Particularmente en el caso del 70% significa que:

Si tenemos un dado de 10 caras, con los números {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Y lo tiráramos, los resultados {1, 2, 3, 4, 5, 6, 7} indicarían que llueve.

Los resultados {8, 9, 10} indicarían que no llueve.

Entonces es mas probable que llueva, pero la probabilidad de que no llueva no es despreciable.

Hope this helps you

Step-by-step explanation:

43. A "Square" cornfield, which means all 4 sides has the same lenght BxH

164.000 ft^2=404.96 NO

156.816 ft^2=396 Yes

174724 ft^2=418 Yes

215908  ft^2=464.66 NO

44. it's the same here, if the area is 81. then each side of the square is 9

1st figure: it has 12 sides x9 =108

2nd figure: it has 10 sides x9=90

3rd figure: has also 12 sides x9=108

45. 13^3= 13x13x13 = 2197

46. 25^2= 25x25 = 625

47.  15^3= 15x15x15 = 3375

48. 34^2= 34x34 = 1156

49.  5 root121= 5 (11)=55

50. -6.root36= - 6 (6)= -36

51.  10 root3 (8) = 10(2) = 20

52. -4. root 144= -4(12) = -48
