After solving, the farmer have total 21 chicken and 19 cows.

In the given question, a farm raises cows and chickens.

The farmer has a total of 40 animals.

One day he counts the legs of all his animals and realizes he has a total of 118 legs.

We have to find how many chickens the farmer have.

Let the number of cows that the farmer have is x.

Let the number of chicken that the farmer have is y.

The farmer has a total of 40 animals.

So the equation should be

x + y = 40....................(1)

As we know that a cow has 4 legs and a chicken has 2 legs.

He has a total of 118 legs.

Now the equation should be

4x + 2y = 118....................(1)

Substituting x = 40 - y from the equation 1, we get

4(40 - y) + 2y = 118

160 - 4y + 2y = 118

160 - 2y = 118

Subtract 160 on both side, we get

-2y = - 42

Divide by -2 on both side, we get

y = 21

Now putting the value of y in x = 40 - y, we get

x = 40 - 21

x = 19

Hence, the farmer have total 21 chicken and 19 cows.

The farmer has 0 chickens and 40 cows.

Let's solve this problem using an algebraic equation. First, we will assign a variable to represent the number of chickens the farmer has. We will call this variable 'x'. We also know that the total number of animals the farmer has is 40. Therefore, we can write an equation that states:

x + (40 - x) = 40

This equation states that the sum of the number of chickens and the number of cows is equal to the total number of animals the farmer has. Now, let's look at the number of legs the animals have. We know the total number of legs is 118. We also know that chickens have two legs and cows have four legs. We can now write another equation that states:

2x + (4(40 - x)) = 118

This equation states that the sum of the number of chicken legs and the number of cow legs is equal to the total number of legs the animals have. We can solve for x by multiplying both sides of the equation by -1 and then adding both equations:

2x + (4(40 - x)) = 118

-2x - (4(40 - x)) = -118

0x = -118 + 118

0x = 0

Since 0x = 0, we can conclude that x = 0. This means that the farmer has 0 chickens and 40 cows.

The angles in the triangle is as follows:

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

Therefore, let's find the angles a, b and c in the triangle as follows:

c + 44 + 53 = 180(sum of angles in a triangle)

c = 180 - 44 - 53

c = 83 degrees

Therefore, let's find the value of a and b.

b + 83 = 180 (sum of angle on straight)

b = 180 - 83

b = 97 degrees.

Hence,

28 + 97 + a = 180(sum of angles in a triangle)

The time Billy should get up to be right on time for school is 6:52 am.

The formula to calculate the time Billy should get up to be right on time for school is as follows: Time Billy Should Get Up = School Start Time - (Time to Get Dressed + Time to Eat Breakfast + Time to Walk to School). In this case, the formula is: Time Billy Should Get Up = 8:35 am - (32 minutes + 13 minutes + 17 minutes). In order to solve this equation, first we must convert the minutes to hours. 32 minutes is equal to 0.53 hours and 13 minutes is equal to 0.22 hours. 17 minutes is equal to 0.28 hours. Thus, the formula is: Time Billy Should Get Up = 8:35 am - (0.53 hours + 0.22 hours + 0.28 hours). Now, we can solve for the time Billy should get up. 8:35 am minus 0.53 hours is 7:42 am. Then, 7:42 am minus 0.22 hours is 7:20 am. Finally, 7:20 am minus 0.28 hours is 6:52 am. Therefore, the time Billy should get up to be right on time for school is 6:52 am.

The first inequality can be solved by combining like terms and isolating x on one side:

-2(6x + 36) - 7x <= 23

-12x - 72 - 7x <= 23

-19x - 72 <= 23

-19x <= 95

x >= -5

The second inequality can be solved by subtracting 10 from both sides:

6x + 10 > 40

6x > 30

x > 5

The solution to both inequalities is x >= -5 and x > 5, which means that x is a real number greater than 5.

The values for the inequality in vertex form is y < -1.5(x - 1)^2 + 4.5

The equation for a parabolic function in vertex form is given by y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

The vertex of the parabolic path of the drinking fountain is (1, 4.5). So, h = 1 and k = 4.5.

Substituting the values for h and k into the equation:

y = a(x - 1)^2 + 4.5

Now, we need to determine the value of a using the point

(x, y) = (2, 4)

So, we have

a(2 - 1)^2 + 4.5 = 4

What is increasing interval?

The interval is expanding if the value of the function f(x) grows as the value of x increases, and it is contracting if f(x) shrinks as x shrinks.

The graph is increasing in between points (-5.5,-2.5) to (-5,0), (-4,-2)to (-3,2.5) and (2,0) to (∞,∞)

The increasing interval is (-5.5,-5)∪(-4, -3)∪ (2,∞).

The graph is decreasing (-5,0 to (-4,2) and (1,2.5) to (2,0).

The decreasing interval of the function is (-5,-4)∪(1,2).

If the value of x for which the value of f(x) is negative, the interval is known as the negative interval.

From the point (-5.5, -2.5) to (-3.25,0), the graph lies below x-axis.

Thus the negative interval is (-5.5, -3.25).

From the point (-3.25,0) to (∞,∞), the graph lies above x-axis.

Thus the negative interval is (-3.25,∞).

The graph of a function y = f(x) has a local maximum at the point where the graph changes from increasing to decreasing. At this point the tangent has zero slopes. At the point when the graph shifts from declining to increasing, a local minimum is present.

The minimum is at (-4,-2) and (2,0).

The maxima are at (-5,0).

The possible value of the x-coordinates of the graph is the domain of the graph.

The domain of the graph is (-5.5,∞).

The possible value of the y-coordinates of the graph is the range of the graph.

The range of the graph is (-2.5,∞).

The y-coordinate of a point at x = a on the graph is the value of f(a).

(-5,0) is a point on the graph. Thus the value of f(-5) is 0.
