Hi!

We will solve this using the system of equations, like this:

x + y = 27

2x + 4y = 78

___________

x = 27 - y

2 * (27 - y) + 4y = 78

54 - 2y + 4y = 78

2y = 24

y = 12

x = 27 - 12 = 15

There are 15 chickens and 12 puppies.

Hope this helps!

abruzzese [7]

Answer:

y = -2x + 6

Step-by-step explanation:

Slope = (-4 - 8)/(5 + 1)

= -12/6

= -2

Equation

y - 8 = -2(x + 1)

y - 8 = -2x - 2

y = -2x + 6  <-----------slope-intercept form

For f(x)= 5^x, find<br> f(3/2)
Sergio039 [100]

Answer:

f(3/2)= 5√5

Step-by-step explanation:

f(3/2)= 5^(3/2)

f(3/2)= (5^3)^1/2  is the same things

f(3/2)= (125)^1/2 fraction exponent are the same are roots ^(1/2) is √

f(3/2)= √125

f(3/2)= √25 times √5 break up 125 to be 25 x 5

f(3/2)= 5√5 because √25 = 5 and √5 stays as √5

Answer:

Hello! Your answer would be BELOW

Step-by-step explanation:

In the history of education the one-room schoolhouse has played an important role in several countries. In the rural areas of the US Midwest and in Norway the one-room schoolhouse was the most common school in the second half of the nineteenth century and the first decades of the twentieth. Although the schoolhouses at first sight seem identical there are some interesting points of distinction in their educational history and how their legacy is interpreted, managed, preserved and promoted today. In the Midwest they are a beloved national icon, often listed, embodying national values and virtues. In Norway their story is effectively untold, not a single one is listed on national preservation lists and by no means do they embody national identity, virtues or values. This article offers an explanation for this different treatment.

Hope I helped! Ask me anything if you have questions! Brainiest plz. Hope You make a 100%! Have a nice day! -Amelia♥
