Answer:
13 sheep, 19 chicken
Step-by-step explanation:
You can start to solve this problem by assigning variables. First, let's assign the number of sheep there are as 
and the number of chickens there are as 
.
Because each sheep has 4 legs, the number of legs for each sheep would be 
. Similarly, because each chicken has 2 legs, the number of legs for each chicken would be 
. Each animal would have 1 head, so the number of heads would just be and . Because the number of legs in total are 90, 
. Because the number of heads in total are 32, 
There is now a system of equations with two unknown variables and two equations. There are many ways to solve this, but for me, the easiest would be elimination. First, I would double the second equation, 
. Then, I would subtract that from the first equation, eliminating . 
. Solving for x gives 13. We can then plug that value into the second equation, making y be 
. This means that 
and 
, meaning that there are 13 sheep and 19 chicken.
Since you need to run six times to get 6/6 miles, or 1 mile, you would have to run 5 times around your neighborhood to complete 5/6 of a mile.
129 degrees is the correct answer for the missing angle number 1 :)
Answer:
The y intercept is (0,-1)
Step-by-step explanation:
To find the y intercept, let x = 0
y = -x^2 -6x-1
y = -0^2-6(0) -1
y = -1
The y intercept is (0,-1)
