I need to Know how to find the maximum and the minimum values of a function?

To divide the 1/4 of a pound into two equal parts, it is necessary to divide 1/4 by 2, as follow:

(1/4)/2

if 2 is written as 2/1, the previous quotient can be written as a product:

(1/4) (1/2) = 1/8

Now, to write a general expression that takes into account the number of siblings, you name the number of siblings as x. Thus, you have:

(1/4)/(x) = 1/(4x)

We get from the question the following equation:

S = d/t

We have the following informations:

Speed(S) = 75 miles /h

Distance(d) = 187.5 miles

If you plug those informations into the formula, you'll get the following:

75 miles/h = 185.5 miles/ t

Now, you just have to solve for "t". If you invert the equation, you'll get(I'm going to omit the units, to make it clearer, but don't forget about them!)

1/75 = t / 185.5

If you multiply both sides by 185.5, you'll get

185.5/75 = t

Solving this calculation, we get the final solution!

t = 185.5/75 hours = 2.47 hours

The amount that each theater make if they received the same number of moviegoers will be $2550.

From the information, 5,780 people saw a new movie at 17 different theaters and each theater sold tickets at $7.50 a piece.

Therefore, the amount that each theater make if they received the same number of moviegoers will be:

= (5780 × $7.50) / 17

= $43350 / 17

= $2550

The cost of the 5 bags using proportionality method is: $36.25

What is proportionality?

In mathematics, the term proportionality can be defined by considering a two quantities in constant ratio. And the two quantities can be recognized as the variable y and x. Where, the variable y is defined as directly proportionate to the changes in the variable x which is based on its constant ratio.

According to the question, the given data states that 5 bags will cost $36.25.

By using proportionality method to solve the given statement.  Put the price over the number of bags

21.75          x

---------- = ---------

3 bags       5 bags

Using cross products defined in standard mathematics,

21.75 * 5 = 3x

108.75 = 3x

Divide each side by 3

108.75/3 = 3x/3

36.25 =x

5 bags will cost 36.25

Hence, the cost of the 5 bags using proportionality method is: $36.25

Dora have 144 shares of stocks while Addison have 37 shares of stocks.

Let us say that Addison own X shares of stock.

According to the situation provided,

The number of shares of stocks own by Dora are 4 less than 3 times of the Stocks owned by Addison.

Stocks Owned by Dora = 3x - 4

The total shares of stocks are 152.

So, we can write the relation between the stocks as,

x + 3x - 4 = 152

4x - 4 = 152

The above formed relations between the stocks is in the form of linear equation in one variable. A linear equation has highest power of variable equal to 1 and only one variable.

Now, solving the equation further,

4x - 4 = 152

4x = 148

x = 37

The total numbers of stocks owned by Addison are 37.

Shares of stocks owned by Dora are 3(37)-4.

The share of stocks owned by Dora are 144.

reason:

since 1 and 4 are equal to each other and because lines AB and CD are parallel, any line crossing both lines will create the same angles in the same areas, thus connecting 4 and 2 together. And since 4 is equal to 1, it is also equal to 2.

We illustrate the division of fractions by taking the example below.

The first step is to change the division sign to multiplication by changing the fraction after the division sign.

Next, we multiply the numerators together and the denominators together.

You then simplify by dividing common factors.

a)  Amount of paint needed for 200 km road = 6250 litres

b)  Length of road that can be painted by using 4000 litres of paint = 128 km

Amount of paint used for painting white lines on road= 250 litres

Length which was painted = 8 km

By using unitary method;

Thus for 1 km amount of paint required = 250/8

= 31.25 litres

a) Amount of paint needed for 200 km road = 31.25 × 200

= 6250 litres.

therefore, Amount of paint needed for 200 km road = 6250 litres

b) Since for 1 km 31.25 liters paint is required this implies with 1 liter = 1/ 31.25 =  0.032 km can be covered.

Length of road that can be painted by using 4000 litres of paint = 4000× 0.032

= 128 km

Thus, Length of road that can be painted by using 4000 litres of paint = 128 km

A single or unique unit is referred to as unitary. Determining values in relation to a single unit is the goal of this strategy. For instance, we can use the unitary technique to determine how many kilometers a car will go on one litre of gas if it travels 44 km on two litres of fuel.

We have to find the line equation of the function shown. We see that passes through the points:

For doing so, we will find the slope and the y-intercept. The slope is given by the expression:

where (x₁,y₁) and (x₂,y₂) are two points of the line. In this case, replacing we obtain:

And thus, the slope is - 1/3. Now, for the y-intercept, we remember that when the x-coordinate is 0, the y-intercept is the y-coordinate.

As the line passes through the point (0,2), the y-intercept will be 2.

Putting those two together, the equation of the line will be:

Answer

The solution is

-3 < x < 3

Explanation

To solve an expression with the absolute value symbol. we obtain two solutions for it.

We first solve when the other side of the equation to the absolute value symbol has positive sign.

Then, we obtain another solution by setting that other side (the right-hand side) to negative. For equations involving inequality signs, the second solution usually changes the inequality sign.

| 2x + 3 | < x + 6

First solution

2x + 3 < x + 6

2x - x < 6 - 3

x < 3

Second solution

2x + 3 > -(x + 6)

2x + 3 > -x - 6

2x + x > -6 - 3

3x > -9

Divide both sides by 3

(3x/3) > (-9/3)

x > -3

So, the solution written together,

x > -3 and x < 3

together, it is

-3 < x < 3

You have to perform two transformations the first one is a 180º rotation with respect to the origin r(180º,O) and the second one is a translation of one unit left and 5 units up T(-1,5)

Given point A(8,-6)

To make a 180º rotation you have to invert the signs of both coordinates, following the rule:

For point A, the rotation is the following:

Once you rotate the point, you have to perform the translation T(-1,5). The rule for the translation can be expressed as follows
