Here is a riddle: “I am thinking of two numbers that add up to 5.678. The difference between them is 9.876. What are the two numbers?”


The riddle can be represented with two equations. Write the equations

Answers

Answer:  

X + Y = 5.678

X - Y = 9.876

The two numbers: X = 7.777   Y = -2.099

Step-by-step explanation: solve by elimination

X + Y = 5.678

X - Y = 9.876 . Add the two equations so the y cancels. Solve for x

2x = 15.554 .  Divide both sides by 2

X = 7.777    Substitute in the original equations to find Y

7.777 + y = 5.678 . Subtract 7.777 from both sides

Y = - 2.099

check in the second equation:

7.777 -(-2.099) = 9.876

7.777 + 2.099 = 9.876 True

The two numbers is X = 7.777 and Y = -2.099.

And, the two equation is X + Y = 5.678  and X - Y = 9.876.

Given that,

I am thinking of two numbers that add up to 5.678. The difference between them is 9.876.Here we assume the one number be X and the other number be Y.

Based on the above information, the calculation is as follows:

X + Y = 5.678

X - Y = 9.876

2x = 15.554  

X = 7.777    

Now  

7.777 + Y = 5.678  

Y = - 2.099

Therefore, the above should be the answers.

What is the slope of the line?

Answers

Answer:

In technical terms, the slope of the line is the change in y over the change in x. But I just like to think of it as rise over run. To find the slope of the line, pick two points on the line.

The slope of the line is -2/1 or -2. Because instead of rising you are going down -2. If you divide -2 by 1 it would be -2, so your slope is -2.

Answers

The average number of people who entered the stadium per minute was 4,160

we know that

To find out the average number of people who entered the stadium per minute, divide the total number of people by the time required to fill the stadium

Let

x ----> the total number of people

y ----> the time required to fill the stadium

we have

1.04*10 5/25 = 4,160 people/mintute

Answer:

A.) This system has no solutions.

Step-by-step explanation:

y = 1/2x + 4

-1/2x + y = -5

-1/2x + (1/2x + 4) = -5

4 = -5

The system has no solutions, if we graph it, we get that it has the same slope with two different y-intercepts, these two are parallel. These two points will never meet at a point.

Answer:

use the relationship between coefficients of a pair of linear equations for no solutions i.e. a1/a2 equal to b1/b2 not equal to c1/c2 .

Here, a is coefficient of x and b is coefficient of y and c is constant term in both equation but make sure that you put the values of a1,a2,b1,b2,c1 and c2 after converting both equation in the form ax+by+c=0 with proper sign and here y=1/2(x) +4 is equation 1 and other is equation 2

350

Step-by-step explanation:

Assumung that the $500 is before taxes, Jamel would have to pay $350.

$500 = price before discount

30% = discount

This means that Jamel would be paying 70% of the orginal price, because 30% of it is already taken off.

Is 3xy + 8 = 4y a linear equation ?

Answers

Answer:

No because of the 3xy term. For an equation to be considered linear there has to be one y value for every x value given

The answer is 3xy + 8 = 4y  is not a linear equation.

What are linear equations?

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: 3xy + 8 = 4y

The degree of this equation is 2 and thus the graph of this equation is not linear.

Hence, 3xy + 8 = 4y  is not a linear equation

Solve x2 – 12x + 26 = 0 by completing the square.

Answers

Answer:

6±√10

Step-by-step explanation:

x^2-12x+26=0

x= ± √10  +6

6±√10

The solutions of the given quadratic equation  [tex]x^2 - 12x + 26 = 0[/tex] are;

x = 6 + √10 and x = 6 - √10.

To solve the quadratic equation [tex]x^2 - 12x + 26 = 0[/tex]

using completing the square method, follow the steps below.

Move the constant term to the right side of the equation

[tex]x^2 - 12x = -26[/tex]

To find the value that completes the square, divide the coefficient of x by 2 and square it.

[tex](-12/2)^2 = 36[/tex]

Add and subtract the value obtained in step 2 to the left side of the equation

[tex]x^2 - 12x + 36 - 36 = -26[/tex]

Simplify the left side of the equation by factoring the perfect square trinomial

[tex](x - 6)^2 - 36 = -26[/tex]

Add 36 to both sides of the equation to isolate the perfect square trinomial

[tex](x - 6)^2 = 10[/tex]

To Take the square root of both sides of the equation

x - 6 = ±√10

Solve for x

x = 6 ± √10

So, the solutions of the given quadratic equation  [tex]x^2 - 12x + 26 = 0[/tex] are x = 6 + √10 and x = 6 - √10.

Oy+8= 5 (1-1)
oy-1-5(x + 8)
Oy-8= + (x+1)

Answers

Answer:

y-1 = 5(x+8)

Step-by-step explanation:

The standard equation of a line in point slope form is expressed as;

y-y0 = m(x-x0)

m is the slope

(x0, y0) is the point

Given

Slope m = 5 (assumed value)

Point (-8,1)

Substitute the given data's into the formula

y -1 = 5(x-(-8))

y-1 = 5(x+8)

BRAINLY Cristina is packing up some evidence in a case she was working on. She got a strange request from the prosecutor: Witness would like her locket back for the sentencing and mitigation hearing, please. She wants the defendant to be able to use it.Intrigued, Cristina reads through the case file. This is what she learns.Milo and Tara have grown up together in the same neighborhood all their lives. When they went to first grade, Milo's dad had an accident at work. He was permanently injured and, for a number of reasons, he never received the right medical care and the family struggled. Milo's dad became addicted to his pain medication as his health got worse.Tara's parents gave her a locket as a gift for starting school. They worked very hard to buy it, and it is one of her most valued possessions. On one side is a photo of her parents, and on the other side is a photo of Tara and Milo.When Milo and Tara were in fourth grade, Milo was having an even tougher time at home. He didn't always have enough to eat, and he almost never got much sleep. His mom worked a night shift, so it was up to him to take care of his younger sisters. Because of all this, he lost his temper and got into a fight at school. It was the first and only time, but it became a disciplinary matter in his file. At the end of the year, Tara was tested for gifted classes, and although Milo was always about at the same level as Tara, or he had been, he was not tested since his disciplinary file disqualified him.By the time Milo and Tara went to seventh grade, Milo's dad had been arrested for his drug use. He was first placed into a diversion program, but the program was far too expensive for the family to manage, and he violated the terms due to nonpayment. He went to prison to serve out his time for the nonviolent drug possession and use offenses. Milo has started working after school so he was tired all the time, and his grades were dropping. Tara continued to do well, and as always, she wore her locket everywhere.At 17, Tara was thinking about going to college. Milo wanted to go, but it just didnt seem possible. Thinking about what he might be missing out on made Milo sad, and he and Tara decided to go have a pizza to relax and have fun for an evening. At the pizza place, some young men started harassing Milo and Tara. One of them yanked Tara's locket off of her neck, cutting into her skin and breaking the chain. Tara screamed and fell to the floor.Milo was shocked. He jumped the man with the locket. He wrestled the locket from the man, but the man and his friends were drunk, laughing and sneering. He made a racist comment to Milo, and Milo snapped. He beat the man upbadly. When he was pulled off, the police were there and the man was unconscious.Tara told the police what happened and begged them not to arrest Milo, but they explained to her that he went way too far. He should have stopped after he recovered the locket. Milo was charged with aggravated assault, and because the man sustained a concussion, Milo faces prison time. His sentencing is next week.Cristina puts down the report, and sighs.In your notes, answer one of the following questions using bulleted notes:As a witness for the defense, what sort of arguments would you make on behalf of Milo at sentencing based on the theories you studied?orBased on your understanding of crime theories, what could be done after the trial to help Milo avoid a similar situation in the future?
