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.
Answer:

Step-by-step explanation:
The given line PQ passes through the points P(-5,-13) and Q(5,17) .
Find the slope using the formula:

Plug in the points to get:



Use the point-slope formula :

Substitute the point (5,17)

Expand:

The standard form is when the equation is put in the form

Regroup the terms to get:

The standard form is

8-3(-12x+2)
=8+-3(-12x+2)
=8+36x+-6
=36x+2
