The given linear system of equation has no solution.

In Mathematics, no solution is also referred to as zero solution, and an equation is said to have no solution when the left hand side and right hand side of the equation are not the same or equal.

In this scenario, we would use an online graphing calculator to plot the given system of equations and then take note of the point of intersection;

x + 3y = 6     ........equation 1.

3x + 9y = 18      ........equation 2.

Based on the graph (see attachment), we can logically deduce that the given system of equations has no solution because both lines are the same and lie on the same co-ordinate.

After 36 minutes of calls, when the function returns a line with a slope of -0.13, there will be $27.56 credit.

Mathematics deals with numbers and their variants, equations and related structures, shapes and their locations, and locations where they might be found. A function is an association between inputs and outputs where each input results in a single, unique output. A domain and a codomain, or scope, are assigned to each function. Functions are typically denoted by the letter f. (x). The input is an x. On functions, one-to-one functions, many-to-one functions, within functions, and on functions are the four main categories of functions that are available.

The two equations that represent the situation are r+s= 1,787 and

4r+3s= 5,792. The solution is obtained using cost function.

What is Cost Function?

A mathematical formula known as a cost function is used to visualise how manufacturing costs will vary depending on the output level. In other words, given a specified quantity produced, it calculates the entire cost of production.

We are given that 'r' represent the number of reserve seats.

So, if 'r' number of reserve seats are sold, then '1,787-r' represents the number of student tickets sold.

Therefore, we get the equation as,

⇒ s= 1,787-r

⇒ r+s= 1,787

Also, we are given that tickets for a reserved seat, r, for the basketball game cost $4 each and student tickets, s, cost $3 each. Total $5,792 was earned in ticket sales.

Therefore, we get the equation as,

⇒ 4r+3s= 5,792

Hence, the two equations that represent the situation are r+s= 1,787 and

4r+3s= 5,792.

Answer: To find the entire parade route, we need to know how many yards the band marched for each of the four sides of the square and then convert those yards to feet.

If the band marched 1,872 yards before their first turn onto Market Street, it means that they also marched 1,872 yards along each of the other three sides of the square.

So the total distance of the parade route in yards is:

1,872 yards + 1,872 yards + 1,872 yards + 1,872 yards = 7,488 yards

To convert that to feet we need to multiply it by 3, since 1 yard equals to 3 feet.

7,488 yards * 3 feet/yard = 22,464 feet

Therefore, the entire parade route was 22,464 feet long.

Step-by-step explanation:

The lateral surface area of the cylinder is 51.22 cm2.

Surface area is a two-dimensional measure that refers to the total area of a surface, such as the area of a two-dimensional shape, a three-dimensional solid, or a combination of both. It is the sum of the areas of all the faces of a solid object. It is also referred to as the area of the boundary of a three-dimensional object. It can be used to calculate the volume of an object, and is also used in other calculations like area of the base of a triangle, area of a circle, and more.

The cylinder shown below has a diameter of 5.2 cm on the base and a height of 7.1 cm. The diameter of the base is referred to as 'd' and the height of the cylinder is referred to as 'h'. The lateral surface area of the cylinder can be found by using the formula LSA = 2πrh, where 'r' is the radius of the base.

The radius of the base of this cylinder is half of the diameter, or 2.6 cm. Therefore, the lateral surface area of the cylinder is: 2π x 2.6 x 7.1 = 51.22 cm2.

V = 236 - 2.5t

O = 0, 2, 5, 6

247, 243, 237, 235

So let's try substituting some numbers in for Valerie.  Let's do 0, 2, 5 and 6 to compare them to Oscar.

V = 236 - 2.5(0)
V = 236

She started at a lesser weight than Oscar.

Week 2:
V = 236 - 2.5(2)
V = 236 - 5
V = 231

So already, at week 2, Valerie lost 5 pounds compared to her first weight.  Oscar lost 4 pounds.  Valerie is losing weight faster than Oscar.

Week 5:
V = 236 - 2.5(5)
V = 236 - 12.5
V = 223.5

From week 2, she lost 12.5 pounds.  Oscar lost 6 pounds.  Looks like Valerie is losing weight faster!

So now, week 6.

V = 236 - 2.5(6)
V = 236 - 15
V = 221
Valerie lost 2.5 pounds compared to week 5.

Oscar lost 2 pounds compared to week 5.

To solve this problem, we need to follow the order of operations (PEMDAS) which stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.

First, we need to perform the multiplication.

11*90 = 990

Next, we add 5 to 990:

990+5 = 995

Finally, we subtract 20 from 995:

995-20 = 975

Therefore, the solution is 975

In summary, we first multiplied 11 and 90, then added 5 to the result, and finally subtracted 20. This is why the order of operations is important because it determines the order in which we perform the calculations in the equation.

Answer:$2.75 for soda 9$ for pizza

Step-by-step explanation: Let p = pizza and s = soda. For the first week, we have the following:

                          24p+24s = 282

Now, for the next week, we have:

                            15p + 8s = 157.

We can multiply the equation 15p+8s=157 by -3 which ends up equaling

                  -45p -24s = -471

Now, we add them.

            24p+24s = 282

            -45p-24s = -471.

The s cancels out and we have -21p = -189. each pizza costs $9, so each soda costs (157-135)/8  which equals $2.75

The ratio of an object's original scale to that of a new, smaller representation is known as the scale factor.

A scale factor is defined as the ratio of an object's original scale to that of a new, smaller depiction of that object (bigger or smaller).

The scale factor is the amount that is multiplied by the original object to create a replica that is smaller but otherwise identical. The only difference between the copy and the original is its size. As though you had used a copy machine to increase or reduce the image or object, scale factor doubles it.

The ratio between the representation and the real thing is indicated by a scale factor. In order to reduce the actual thing's dimensions, a precise depiction of the object is called a scale drawing.

Step-by-step explanation:

Karen sent 16, Chau sent 72 and Goran sent 24 messages over their phones during the weekend.  

Here we use the concept of Linear equation to find the Number of messages sent by each person. A linear Equation is a mathematical statement that is formed by constant and variable terms.

Given that

Karen, Chau, and Goran sent a total of 112 text messages over their cell phones during the weekend.

[Since we don't know the number of messages sent by each person take them as different variables. ]

Let x, y, and z be the number of messages that Karen, Chau, and Goran sent respectively

=> x + y + z = 112 ---- (1)

Given that

Chau sent 3 times as many messages as Goran.  

=> y = 3z --- (2)  

Goran sent 8 more messages than Karen.

=> z = x + 8

=> x = z - 8 --- (3)

From (1) (2) and (3)

=> z - 8 + 3z + z = 112  

=> 5z = 120      

=> z = 24

From (3)

=> x = 24 - 8 = 16    

From (2)

=> y = 3(24) = 72  

Therefore,

Karen sent 16, Chau sent 72 and Goran sent 24 messages over their phones during the weekend.

Answer: The sum of the cubes of the roots of a quadratic equation with coefficients a, b, and c can be found using the formula:

x³ + y³ = (x + y)(x² - xy + y²) = -b

Where x and y are the roots of the equation ax² + bx + c = 0.

In this case, the equation is 2x² - 10x + 12 = 0, so a = 2, b = -10, and c = 12.

So, the sum of the cubes of the roots is:

x³ + y³ = -b = -(-10) = 10

Therefore, the sum of the cubes of the roots of the equation 2x² - 10x + 12 = 0 is 10.
