A system of equations is shown below.
y=-2x + 6
6x + 3y = 18
What is the solution to the system of equations?
(Show work)

Answers

Answer 1

Answer:

Step-by-step explanation:

First, we need to look at the simpler equation. We see that the top equation is the simpler one.

y=-2x + 6

Now we plug that equation with the other one.

6x + 3(-2x + 6) = 18

6x -6x + 18 = 18

18 = 18

Since we see that 18 = 18. We know that this equation is a true equation. We can plug the y-variable in first and it will still be a true statement.

- Chong waits on tables at a restaurant. One day he served 4 different tables with bills without tips
as follows: $85.40, $125.00, S92.60, and $155.50. If he earned an average of 12% on tips for the
value of the meals, how much did he make on tips from the 4 tables?

Answers

Answer:

$55.02

Step-by-step explanation:

Sum up the bills:

85.40 + 125.00 + 92.60 + 155.50 = 458.5

Find 12% of the sum:

458.5*12/100 = 55.02

Total bill:-

85.4+125+92.6+155.5=458.5$

During an experiment, the temperature of a mixture changes from 12 1/4°F to 15 3/5°F. What is the percent of increase in the temperature of the mixture?

Answers

The percentage increase is  21.4% increase

Given Data

Initial temperature =  12 1/4°F = 49/4 = 12.25°F

Final Temperature =  15 3/5°F = 78/5 = 15.6°F

We know that the expression for percentage increase is given as

Percent Increase = Increase/Final *100

Percent Increase = 15.6-12.25/15.6 *100

Percent Increase = 3.35/15.6 *100

Percent Increase = 0.214 *100

Percent Increase = 21.4%

Hence there is a 21.4% increase

What are the benefits of creating and using functions in your code?.

Answers

It is critical to remember that creating functions while coding is a vital component of coding. There are various benefits to doing so.
A few of the advantages include the following:

The function can be called from anywhere in the code and made to perform exactly what it was written for the first time if it is called from a different line of code.

2. Writing functions reduces redundancy by allowing for fewer lines of code to be written in total. It eliminates the need to rewrite numerous lines of code over and over again. After the initial line of code has been set, we can call the method from another location.

3. It increases the efficiency of coding.

4. It makes it easier for others to comprehend the fundamentals involved in a coding structure, which is an advantage.

Luke buys a certain brand of cereal that costs $11 per box. Luke changes to a super-saving brand of the same size. The equation shows the price, y, as a function of the number of boxes, x, for the new brand.

y = 9x

Part A: How many more dollars is the price of a box of Luke's original brand of cereal than the price of a box of the super-saving brand? Show your work.

Part B: How much money does Luke save each month with the change in cereal brand if he buys 6 cereal boxes each month? Show your work. (10 points)

Answers

Answer:

See below.

Step-by-step explanation:

Part A

"y = 11x is the function for the original boxes that he bought...it was $11 per box.

y = 9x is the function for the super saving brand...it is $9 per box

so there is a $2 difference between the original and the super saver."

Part B

"original box.....6 cereals

y = 11(6)

y = 66

super saver....6 cereals

y = 9(6)

y = 54

66 - 54 = 12.....so Luke saves $12 per month by buying the super saver brand."

When creating a right triangle using 3 squares as seen in the online video, which sides create the right angle in the triangle?

Answers

When creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle (see image attached below).

Creating a Right Triangle with Three Squares

The right angle of a right triangle is formed by the two small legs of the right triangle that are perpendicular to each other.

Just like in the diagram attached below, the two squares with the smallest sides will form the right angle in the right triangle.

Therefore, we can conclude that when creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle.

How do I find the percent of a number?

Answers

Answer:

[tex]\frac{x}{100} =[/tex] the value you are solving for over total value.

Step-by-step explanation:

The way I learned it was like this:

Let's say you're trying to find the percent of red marbles there are in a pile. You have 24 red marbles and there are 48 in all. Set it up like so:

[tex]\frac{x}{100} =\frac{24}{48}[/tex]

x is over 100 because all percents are out of 100, and 24 is over 48 because that's the value you are trying to solve the percent for. Then cross-multiply.

[tex]\frac{x}{100} =\frac{24}{48}\\48(x)=24(100)\\48x=2400[/tex]

Then divide.

[tex]48x[/tex] ÷[tex]48x=2400[/tex] ÷ [tex]48[/tex]

[tex]x=50[/tex]

So the percentage is fifty.

Approximately how many square inches of fabric were used to make the triangular flag? 15 square inches 76 square inches 186 square inches 215 square inches.

Answers

The area used to make the triangular flag is 15 square inches.

Given

Two of the sides are 8 in.

Lila made a triangular flag to cheer on her favorite sports team.

The perimeter of the flag is 20 inches.

What is Heron’s formula?

Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.

Then,

The value of S is;

[tex]\rm S = \dfrac{20}{2}\\\\S =10[/tex]

Therefore,

The area used to make the triangular flag is;

[tex]\rm Area = \sqrt{s(s-a)(s-b)(s-c)} \\\\A rea= \sqrt { (10)(10-8)(10-8)(10-4) }\\\\Area = \sqrt{10 \times 2 \times 2\times 6}\\\\Area = \sqrt{240}\\\\Area = 15.49[/tex]

Hence, the area used to make the triangular flag is 15 square inches.
