The answer is C: (-3,-1)

To test if points satisfy an equation, all you need to do is test the numbers in both of the equations it provides you

Here is proof the answer is C :

<em>y > x - 2 </em>

(lets plug in point C)

-1 > -3 - 2

<u>solve </u>

-1 > -5 <em>?</em>

<em>Yes</em> this statement is true- onto the next inequalitity!

<em>y > 2x + 2 </em>

-1 > 2(-3) + 2

<u>solve </u>

-1 > -6 + 2

-1 > -4<em> ? </em>

<em>Yes, </em>this inequality is true too!

Know we know answer c (-3,-1) is the right answer!

Answer:

There are 29 chickens and 19 sheep.

Step-by-step explanation:

Samantha has chickens and sheep on her farm.

Let the number of chickens be c.

Let the number of sheep be s.

Each chicken has one head and each sheep has one head.

She looked out one day and counted 48 animal heads. Each chicken has one head and each sheep has one head.

This means that the number of chickens and sheep add up to 48:

c + s = 48 ____________(1)

She also counted 134 legs. Each chicken has one head and each sheep has one head. This means that:

2c + 4s = 134 ________(2)

From (1),

c = 48 - s ____________ (3)

Put (3) in (2):

2(48 - s) + 4s = 134

96 - 2s + 4s = 134

Collecting like terms:

2s = 134 - 96

2s = 38

s = 38 / 2 = 19

Putting this back in (3):

c = 48 - 19

c = 29

There are 29 chickens and 19 sheep.
