A system of inequalities to model the situation using x, the number of adult tickets, and y, the number of child tickets is x + y ≤ 200 and 10x + 5y ≥ 750.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides.

Let the number of adult tickets = x

Let the number of child tickets = y

The total number of tickets that can be sold = 200

So, the inequality will be -

x + y ≤ 200

Adult tickets costs $10.00 and child tickets costs $5.00.

The total amount of tickets that can be sold = $750

So, the inequality will be -

10x + 5y ≥ 750

Therefore, the inequality equations are - x + y ≤ 200 and 10x + 5y ≥ 750.

The parentheses are used to indicate that (x - 1) is a single quantity being multiplied by 13.2.

The result of two numbers being multiplied in any order is unaffected, according to the commutative property of multiplication.

In other words, if a and b are any two numbers, then a * b = b * a.

Using the commutative property, we can write:

13.2 (x - 1) = (x - 1) 13.2

This means that the product of 13.2 and (x - 1) can be computed in either order, and the result will be the same.

Answer:

a) x=15

b)x=12

Step-by-step explanation:

a) x/5=3

to get x by itself, undo the division and multiply the 5 on both sides

b) x/2=8.5

to get x by itself, undo the division and multiply the 2 on both sides

Answer:

The system of equations "a)x/5=3" and "b)x/2=8.5" has no solution because the two equations contradict each other. Solving the first equation for x gives us "x=15", while solving the second equation for x gives us "x=17". Since x cannot have two different values at the same time, there is no value of x that makes both equations true.

The solution of the system of equations y = x² + 6x + 9 and y = -x + 3 is (-6, 9) and (-1, 4)        

An equation shows the relationship between numbers and variables in an expression.

From the system of equation:

y = x² + 6x + 9   (1)

And:

y = -x + 3      (2)

Using substitution method, substitute y = -x + 3 into equation 1:

-x + 3 = x² + 6x + 9  

x² + 6x + x + 9 - 3 = 0

x² + 7x + 6 = 0

x² + x + 6x + 6 = 0

x(x + 1) + 6(x + 1) = 0

(x + 6)(x + 1) = 0

x = -6 or x = -1

substitute value of x to get y:

when x = -6; y = -(-6) + 3 = 9        

when x = -1; y = -(-1) + 3 = 4

Step-by-step explanation:

The center of the circle is [tex](-3,3)[/tex] and the circle passes through [tex](0,1)[/tex].

So, the square of the radius is [tex](-3-0)^2+(3-1)^2=13[/tex].

Substituting into the center-radius form for the equation of a circle, the equation is [tex](x+3)^2+(y-3)^2=13[/tex].

The equation of circle is [tex](x + 3 )^2 + (y - 3)^2 = 13[/tex] whose center is at (-3, 3).

The standard form of the equation of a circle is:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

In this equation, (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

From the figure, the center of circle is at (-3, 3) and the passing point is (0, 1).

So, the radius of circle is

= √( 3-1)² + (-3-0)²

= √2² + 3²

= √13

Now, the equation of circle is

The number conjecture that proves the given assertion is;

D) Let (2a + 1) be one odd number, and let (2b + 1) be the other odd number. (2a + 1) + (2b + 1) = 2a + 2b + 2 = 2(a + b + 1). Because 2(a + b + 1) is a multiple of 2, it is an even number.

Number Conjecture is also called Goldbach conjecture which is defined as a number theory that states that every even counting number greater than 2 is equal to the sum of two prime numbers.

Now, when we multiply any number by two, it will become even. We can also see that, if we divide any number by two without a remainder, it will be even. In this question, we can say that;

Let (2a + 1) be one odd number.

Let (2b + 1) be the other odd number. Thus;

(2a + 1) + (2b + 1) =

2a + 2b + 2 =

C) Let a and b both represent odd numbers, and let a + b be an even number. Therefore, a + b = b + a, which shows that the sum of two odd numbers is even.

D) Let (2a + 1) be one odd number, and let (2b + 1) be the other odd number. (2a + 1) + (2b + 1) = 2a + 2b + 2 = 2(a + b + 1). Because 2(a + b + 1) is a multiple of 2, it is an even number.

The cost of driving a car for a trip will be $356 and for air, the trip will be $275.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Rob and Janice had to choose between making a 600-mile trip by car or by plane. Round-trip airfare was $260 for each of them and would take 2 hours. Round-trip cab fare to the airport would add another $15.

Driving their own car would take 2 days each way and would add the cost of gas, food, and lodging. Janice estimated that gas would cost $60, that food would cost $25 per day (4 days) for each of them, and that lodging would be $48 for each night of the 2 nights they would stay in a motel.

The driving cost:-

Answer: To estimate the height of Big Tex, we can use the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the length of the hypotenuse is the height of Big Tex, and the two other sides are the distance from Dami to Big Tex (24 feet) and the height of Dami's eyes above the ground (6 feet).

So, if we call the height of Big Tex "h",

h^2 = 24^2 + 6^2

Solving for h,

h = sqrt(24^2 + 6^2)

h ≈ 45

So Big Tex is about 45 feet tall to the nearest foot.

Solving systems of equations by elimination is a method of finding the solutions to systems of equations with two or more variables. To do this, the equations are manipulated so that the two variables can be canceled out, resulting in a simpler equation. This simpler equation can then be solved using basic arithmetic. Depending on the equations, different methods may be used to manipulate them, such as adding them together or subtracting one from the other.

The measure of angle ∠8 by using the properties of supplementary, opposite, and corresponding angle will be 72°

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

The properties of the angle are as follows:

Given that m∠2 = 2x and m∠3 = 3x.

Angles ∠2 and ∠3 are the supplementary angle. Then we have

∠2 + ∠3 = 180

2x + 3x = 180

5x = 180

x = 36

The measure of angle 2 is given as,

∠2 = 2(36)

∠2 = 72°

Angles ∠2 and ∠4 are opposite angles. Then we have

She also correctly isolated the cost and found its value to be 0.1276. However, when she solved for B, instead of using the inverse cosine function, arccos(0.1276), she used the cosine function with the value 0.1276 which resulted in an angle of 82.7 degrees. The correct value of B as per the provided equation should have been arccos(0.1276) which is not equal to 82.7.
