Solve Each System Of Equations Using The Substitution Method Give The Solution In (x,y) Form

Answers

Answer 1

Step-by-step explanation:

y=-3+5x

substitute y into equation 2

3x-8y=24

3x-8(-3+5x)=24

3x+24-40x=24

x=0

y=-3+5(0)

y=-3

(x,y)=(0,3)

Solve: 2x + 3y = 1
y = -23 +11

Answers

Answer:

x = 18.5

y = -12

Step-by-step explanation:

First, solve y:

y = -23 + 11

y = -12

Then, solve the main problem:

2x + 3y = 1

(Substitute y)

2x + -36 = 1

2x - 36 = 1

2x = 1 + 36 = 37

x = 37 / 2

x = 18.5

Answer:[tex]\boxed{\boxed{\sf{x=19.25}}}[/tex]Solution Steps:

______________________________

1.) Subtract 17 from both sides:[tex]17-17=[/tex] Cancels Out[tex]94-17=77[/tex]

 - We do this to get 1 number left over at the end sum of the equation. To do this you do the opposite of what you see. In this case we have a positive 17, so you subtract 17 on each side.

2.) Divide both sides by 4:[tex]4x[/tex] ÷ [tex]4=x[/tex][tex]77[/tex] ÷ [tex]4=19.25[/tex]

 - We do this to get x alone. To do this you do the opposite of what you see. In this case we have [tex]4(x)[/tex] being multiplied, so you divide by 4 on each side.

So your answer is [tex]\bold{19.25}[/tex].

______________________________

Answer:

x= 77/4

Step-by-step explanation:

(You will first have to rearrange terms)

17+4x-94

4x+17=94

(Now you will have to subtract 17 from both sides of the equation.)

4x+17=49

4x+17-17=94-17

(You will have to simplify now)

4x=77

(You will have to divide from both sides of the equation by the same term.)

4x=77

4x=77

---  ---      (Divide by 4.)

4    4

(you will now simplify)

x=77/4

and that's how you get your answer.

There are three possible outcomes for a system of linear equations: one unique solution, infinitely many solutions, and no solution.

Step-by-step explanation:

9514 1404 393

Answer:

no solutionsa finite non-zero number of solutionsinfinite solutions

Step-by-step explanation:

1. No Solutions

This case arises when the equations are inconsistent. No values of the variables can satisfy all of the equations. An example is ...

y = xy = x+1

__

2. Finite Number of Solutions

The number of distinct solutions depends on the degree of the system and the domain being considered. For example, an n-th degree polynomial equation in one variable will always have n solutions in the domain of complex numbers. However, it may or may not have any real-number solutions. (The question here has no context, so we have to assume it is about any system of equations of any degree or nature (rational, polynomial, exponential, mixed, or other.))

__

3. Infinite solutions

An under-specified system, such as a system of 3 equations in 4 variables, may have an infinite number of solutions. In such a system, one or more of the variables may be allowed to assume any value. Systems that have dependent equations will fall into this category.

I need this very quickly

Answers

Answer:

P = 201.

Step-by-step explanation:

In mathematics, distributivity is a property of binary operations in which the multiplication is distributed, dividing the same multiplier by the different multipliers to obtain the result.

Thus, to solve the equation -4 (P - 212) = 44 the following calculation must be performed:

-4 (P - 212) = 44

(-4 x P) - (-4 x 212) = 44

-4P - (-848) = 44

-4P + 848 = 44

-4P = 44 - 848

-4P = -804

P = -804 / -4

P = 201

Karen recorded the numbers of people getting off her tram. The mean number for 10 stops is 6.3. After the tram stops at the 11th stop, the mean is 8. How many people got off the tram at the 11th stop?

Answers

Answer:

32 people got off

Step-by-step explanation:For the 10th stop, we can get the total number of people that have gotten off

Mathematically, this is the product of the mean and the number of stops

= 10 * 6.3 = 63 people

Now, for the 11th stop, the total becomes

11 * 8.6 = 94.6

Mario made 2 goals for every 5 shots on goal. What is the probability that Mario would make 2 goals on two shots?

Answers

Answer:

16%

Step-by-step explanation:

To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.

2 / 5 = 0.4  ...multiply by 100 to get percentage value

0.40 * 100 = 40%

We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.

0.40 * 0.40 = 0.16  ... multiply by 100 to get percentage value

0.16 * 100 = 16%

Answer:

16%

Step-by-step explanation:

I know that 2/5 = 0.4 or 40%

and 0.4 x 0.4 = 0.16

or 16%

The table shows the types of movies and the number of DVDs reented by customers at a Red Box in one

Based on the data in the table, what is the probability that a random customer will not rent a drama?

Answers

Answer:

A

Step-by-step explanation:

The probability that a random customer will not rent a drama is 4/5. Option B is correct.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

here,
Total number of rented DVDs = 25 + 36 + 52 + 12 = 125
Number of Drama movies = 25

The probability that a random customer will rent a drama.
P(D) = 25 / 125 = 1/5

Now,
The probability that a random customer will not rent a drama,
P(D)' = 1 - P(D)
       = 1 - 1/5 = 4/5

Thus, the probability that a random customer will not rent a drama is 4/5. Option B is correct.

A rectangular dog pen has an area of 64xy square units. The width is 4y. Write an expression for the length.

Answers

Answer:

An expression for the length is:

[tex]l=16x[/tex]

Step-by-step explanation:

Given

Area of a rectangular dog pen = A = 64xy square units

Width = w = 4y

To determine

The length = l = ?

We know that the area of a rectangular object is

A = l × w

where w is the width and l is the length of the rectangle.

substituting w = 4y and A = 64xy in the equation

[tex]A=l\times w[/tex]

[tex]64xy\:=l\times 4y\:[/tex]

[tex]\:\:l=\frac{64xy\:}{4y\:\:}[/tex]

Divide the numbers: 64/4 = 16

[tex]l=\frac{16xy}{y}[/tex]

Cancel the common factor: y

[tex]l=16x[/tex]

Therefore, an expression for the length is:

[tex]l=16x[/tex]
