To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this? because the system of equations actually has only one solution because the system of equations actually has no solution because the graphs of the two equations overlap each other because the graph of one of the equations does not exist

5/2x = 1

2/5 x 5/2x = 1 x 2/5

x = 2/5

Answer:

x = 2/5

Explanation:

Step 1: Multiply both sides by 2/5.

(2/5) * (5/2x) = (2/5) * (1)

Step-by-step explanation:

you multiply 30 with 0.7 to get the tax then divide by 20% of that to get the answer

Answer:

bill = $30

sales tax = 0.07         from 70%

tip = 0.2      from 20%

After Tax Bill = Bill * (1 + sales tax)

After Tax Bill = $30 * (1 + 0.07)

After Tax Bill = $30 * 1.07

After Tax Bill = $32.1

Total Bill = After tax Bill * (1 + tip)

Total Bill = $32.1 * (1 + 0.2)

Total Bill = $32.1 * 1.2

Total Bill = $38.52

Answer:

The number of

Fiction books = x = 2400 fiction books

Non fiction books = y = non fiction books

Step-by-step explanation:

Let the number of

Fiction books = x

Non fiction books = y

The libary has 4,000 books in total.

Hence: x + y = 4000........ Equation 1

The number of fiction books in a libary is %150 of the number of non-fiction books.

x = 150% of y

x = 150/100 × y

x = 1.5y

We substitute 1.5y for x in Equation 1

x + y = 4000

1.5y + y = 4000

2.5y = 4000

y = 4000/2.5

y = 1600 non fiction books

Solving for x

x = 1.5y

x = 1.5 × 1600

x = 2400 fiction books.

Therefore,

The number of

Fiction books = x = 2400 fiction books

Non fiction books = y = non fiction books

Answer:

x = 2y + 16

Step-by-step explanation:

     [tex]\frac{x}{2} - 8 = y[/tex]

[tex]\frac{x}{2} - 8 + 8 = y + 8[/tex]                   (adding 8 to both sides)

           [tex]\frac{x}{2} = y + 8[/tex]

         [tex]\frac{x * 2}{2} = (y + 8)*2[/tex]           (multiplying both sides by 2)

            [tex]x = 2y + 8 * 2[/tex]

            [tex]x = 2y + 16[/tex]

Answer: 5p - 6

Step-by-step explanation:

Brendan has six less than five times the number of pencils that Riley has.

P = the number of pencils Riley has.

The algebraic expression that represents the number of pencils Brendan has in terms of p, the number of pencils that Riley has would be:

= (5 × p) - 6

= 5p - 6

For example, if Riley has 5 pencils, the number of pencils that Brendan would have would be:

= 5p - 6.

= 5(5) - 6

= 25 - 6

= 19 pencils

Hope it helps!

Answer: Interest = Principal × Rate × Time

100

=> 6450×3.7×1

100

=> $238.65

Step-by-step explanation:

The two ways to write the algebraic expression is the quotient of p and 29 and or p divided by 29. Option A

Algebraic expressions are expressions comprising of variables, terms, factors, coefficients, constants.

These expressions are also made up of arithmetic operations such as;

From the information given, we have the expression as;

p ÷ 29

It is important to note that the sign for division is '÷' or '/’

Division is an arithmetic operation is also called quotient.

Now, we can say that;

p ÷ 29 is the quotient of p and 29 and or p divided by 29.

Thus, the two ways to write the algebraic expression is the quotient of p and 29 and or p divided by 29. Option A

Answer:

y = [tex]\frac{3}{2}[/tex] x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{3}{2}[/tex] , then

y = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

To find c substitute (- 4, - 7 ) into the partial equation

- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1

y = [tex]\frac{3}{2}[/tex] x - 1 ← equation of line

There is nothing wrong with you. Everyone ad their ups and downs

This is a process that happens in most humans. most often happening to teenagers due to their increased hormones during their puberty.  I would recommend getting attached to music as a form of reliance. I too had my days when I would be depressed but I got through it by attaching myself to something rather than someone. people's actions in real life during this time can seem exaggerated to you so it would be best to just ignore people for now if you are sensitive and just listen to music, study, or read a book to take your mind off the stress. However, based on the current trends I would recommend you to get attached to this thing called Kpop. recently I conducted a survey and many people said they were happier watching stuff about pretty people rather than going out and socializing. you could attach yourself to a particular idol and "stan" them as it would keep your mind off people. however, this method although effective can lead you to become a brain dead fan who will waste money and become a loner I suggest that if taking this idol attachment approach that you go out and try to connect with new people or try to reunite with your old people too so that you don't lose touch with reality. And lastly, it could be just that this Current situation stress is weighing too heavily on you and you have mistaken it and you just need a period of rest to get your bearings back. I recommend you try a period of resting and self-indulgence, then if that doesn't work music, and if the music doesn't work then attach yourself to an idol. Don't give up and try something new

Answer: The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope. y = mx+b is the equation to get slope.

The required characteristic that has a high survival value in a population is likely to become dominant or common.

Statistics is the study of mathematics that deals with relations between comprehensive data.

A characteristic that has a high survival value in a population is likely to become more common over time. This is because individuals with this characteristic are more likely to survive and reproduce, passing the trait on to their offspring. Over generations, this process, known as natural selection, can lead to an increase in the frequency of the advantageous trait in the population. Over time, the characteristic that has a high survival value in a population is likely to become dominant.

Thus, the required characteristic that has a high survival value in a population is likely to become dominant or common.
