The maximum and minimum of the given function are 22 and -2, respectively

The system of inequalities is given as

y ≥ -x - 2

y ≥ 3x + 2

y ≤ x + 4

See attachment for the graph

From the graph, we have the following coordinates

(-1, -1), (-3, 1) and (1, 5)

Substitute (-1, -1), (-3, 1) and (1, 5) in f(x, y) = -3x + 5y

So, we have

f(-1, -1) = -3(-1) + 5(-1) = -2

f(-3, 1) = -3(-3) + 5(1) = 14

f(1, 5) = -3(1) + 5(5) = 22

Hence, the maximum is 22 and the minimum is -2

The prove that triangle ABE is congruent to triangle CDE is given below

Generally, To prove that triangle ABE is congruent to triangle CDE, we need to show that they have the same size and shape.

First, we can see that angle AED and angle CEB are opposite angles and therefore congruent, since AB || DC.

Also, since line AB = line DC, we know that segment AE is congruent to segment CE and segment BE is congruent to segment DE.

Using these congruent sides and the congruent angle, we can apply the Side-Angle-Side (SAS) congruence criterion to conclude that triangle ABE is congruent to triangle CDE.

Therefore, we have proven that triangle ABE is congruent to triangle CDE.

a. The six trigonometric functions of the angle β are:

sin β = 7/25

cos β = 24/25

tan β = 7/24

csc β = 25/7

sec β = 25/24

cot β = 24/7

b. Using trigonometric identity, cos X + (sin X)(tan X) = 1

We can use the given value of cos β = 24/25 to find the other trigonometric functions of the angle β.

Let's draw a right triangle with angle β, adjacent side of length 24, and hypotenuse of length 25 (since cos β = adjacent/hypotenuse):

Using the Pythagorean theorem, we can find the opposite side:

Opposite side = sqrt(hypotenuse^2 - adjacent^2) = sqrt(25^2 - 24^2) = sqrt(49) = 7

So the triangle is:

Now we can find the other trigonometric functions:

sin β = opposite/hypotenuse = 7/25

cos β = adjacent/hypotenuse = 24/25

tan β = opposite/adjacent = 7/24

csc β = hypotenuse/opposite = 25/7

sec β = hypotenuse/adjacent = 25/24

cot β = adjacent/opposite = 24/7

2. We can use the trigonometric identity for tangent:

tan X = sin X / cos X

to rewrite the expression as:

cos X + (sin X)(sin X / cos X)

Multiplying through by cos X, we get:

(cos X)(cos X) + (sin X)(sin X)

Using the Pythagorean identity:

(sin X)^2 + (cos X)^2 = 1

we can simplify further:

1 - (cos X)^2 + (cos X)^2 = 1

So the final simplified expression is equal to 1

3. We can start with the left-hand side of the equation and manipulate it using the definitions of the trigonometric functions and the Pythagorean identity until we arrive at the right-hand side:

tan²α(csc²α - 1)

= (sin²α/cos²α)((1/sin²α) - 1)

= (sin²α/cos²α - sin²α/cos²α)

= 0

Now, let's look at the right-hand side:

1

We see that the left-hand side simplifies to 0, while the right-hand side is 1. Therefore, the identity is not true for all values of α.

We can see this more clearly by picking a specific value of α and evaluating both sides of the equation. For example, let's take α = 45°:

tan²45°(csc²45° - 1) = (1/1)((2/1) - 1) = 1

1 = 1

So the identity holds for α = 45°, but we have already shown that it does not hold for all values of α. Therefore, the identity is not true for all values of α.

Step-by-step explanation:

This could result in one, two, or multiple points of intersection, depending on the specific values of the deposits and the rates of increase.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

we can assume that the graph of Cera's and Bethany's savings accounts will show the total amount of money in their accounts after a certain number of weeks.

Since both Cera and Bethany deposit the same amount of money and make the same additional deposits each week, their savings will increase at the same rate. Therefore, the graph will likely show two parallel lines that start at $20 and increase by $15 per week.

The number of solutions modeled by the graph will depend on whether the two lines ever intersect. If the lines do not intersect, then there is no solution to the system of equations that model the two savings accounts. In other words, there is no point at which the total amount of money in both accounts is the same.

On the other hand, if the lines do intersect, then there is at least one solution to the system of equations. In this case, the point of intersection represents the week at which the total amount of money in both accounts is the same.

To change the situation so that the graphs model a different number of solutions, we could change the initial deposit or the amount of money deposited each week for one or both of the savings accounts. For example, if Cera starts with a higher initial deposit than Bethany, or if Cera deposits more money each week, then their savings will increase at different rates and the lines on the graph will not be parallel.

Therefore, This could result in one, two, or multiple points of intersection, depending on the specific values of the deposits and the rates of increase.

Answer:

Step-by-step explanation:

We can start by setting up an equation to solve for x, the number of years it will take for the car to be worth $8,200:

8200 = 20000(0.8)^x

Dividing both sides by 20,000, we get:

0.41 = 0.8^x

Taking the logarithm of both sides (using any base, as long as we're consistent), we get:

log(0.41) = log(0.8^x)

Using the property of logarithms that allows us to bring down the exponent as a coefficient, we get:

log(0.41) = x log(0.8)

Dividing both sides by log(0.8), we get:

x = log(0.41) / log(0.8)

Using a calculator, we find:

x ≈ 5.92

Therefore, it will take about 5.92 years for the car to be worth $8,200.

The price per pound of the carrots Dora bought is $0.80.

What is the unit rate?

Unit rate is a ratio that compares the amount of one unit of measure to the corresponding amount of another unit of measure. It is a special case of a ratio, in which the second term is always one. For example, if a car travels 120 miles in 2 hours, the unit rate of speed is 60 miles per hour, which means that the car travels 60 miles for every hour of driving.

Unit rate is commonly used in everyday life, such as in shopping (price per unit) or in cooking (ingredients per serving).

To find the price per pound of the carrots, we need to divide the total cost by the total weight.

First, we need to convert the mixed number 4 1/2 to an improper fraction:

4 1/2 = (4 x 2 + 1) / 2 = 9/2

Next, we divide the total cost by the total weight in pounds:

Price per pound = Total cost / Total weight

Price per pound = $3.60 / 4.5 pounds

Price per pound = $0.80

Therefore, the price per pound of the carrots Dora bought is $0.80.

What is average rate ?

Average rate refers to the rate of change of a quantity over a given period of time. It is calculated by dividing the change in the quantity by the time period over which the change occurs.

To find the average rate of change in cost per class, we need to calculate the slope of the linear function that relates the gym fee to the number of classes taken.

Let x be the number of classes taken, and y be the gym fee. We can use the two data points given to find the equation of the line:

When x = 6, y = 43

When x = 11, y = 73

The slope of the line passing through these two points can be calculated as follows:

slope = (change in y) / (change in x)

slope = (73 - 43) / (11 - 6)

slope = 30 / 5

slope = 6

A histogram is a graph used to represent the frequency distribution of a few data points of one variable. Histograms often classify data into various “bins” or “range groups” and count how many data points belong to each of those bins.

The histogram shows the number of items sold at various price ranges, and the heights of the bars indicate the number of items sold within each price range.

The data set that is represented in the histogram is:

{0.50, 2.00, 2.52, 3.37, 4.53, 5.00, 8.99}

This is because the histogram has four bars with heights of 2, 4, 0, and 1, which correspond to the number of items sold in each of the four price ranges shown.

The values in the data set correspond to the boundaries of these price ranges. For example, the first bar represents the price range from $0.00 to $2.50, so the data set includes the value 2.00 (which is within this range) and the value 2.52 (which is just outside this range).

Similarly, the second bar represents the price range from $2.51 to $5.00, so the data set includes the value of 4.53 (which is within this range) and the value of 5.00 (which is the upper boundary of this range).

Therefore, the second bar represents the price range from $2.51 to $5.00, so the data set includes the value of 4.53 and the value of 5.00 the correct answer is {0.50, 2.00, 2.52, 3.37, 4.53, 5.00, 8.99}
