Answer:

The discriminant is -23

The equation has 0 real solution

Step-by-step explanation:

The discriminant of the quadratic equation ax² + b x + c = 0 is Δ = b² - 4ac

If Δ > 0, then the equation has two different real solutionsIf Δ = 0, then the equation has one real solutionIf Δ < 0, then the equation has no real solutions

Let us use the rule above to solve the question

∵ x² - x + 6 = 0

∴ a = 1, b = -1 and c = 6

∵ Δ = b² - 4ac

∴ Δ = (-1)² - 4(1)(6)

∴ Δ = 1 - 24

∴ Δ = -23

∴ The discriminant is -23

∵ -23 < 0

∴ Δ < 0

∴ The equation has no real solutions

∴ The equation has 0 real solution

I need help finding the equation for y

Answers

Answer: y = -6x - 2

Step-by-step explanation:

54x + 15 = -3(3y + 1) To solve for y distribute on the right side to get,

54x + 15 = -9y -3 Add 3 to both sides

+3 +3

54x + 18 = -9y Divide each term by -9 on each side.

y = -6x - 2

Answer______

54x + 15 = -3 (3y + 1)

54x + 15 = -9y -3

+3 +3

54x + 18 = -9y

y = -6x - 2

Answers

Answer:

The minimum number of weeks Clarissa needs to save is 6 weeks.

Step-by-step explanation:

Clarisaa wants to go to the concert with the luke bryan

Ticket cost=$54.50

Inequality= 25+5w[tex]\geq[/tex] 54.50

upon solving the inequality we get

5w [tex]\geq[/tex] 54.50-25

What is an equation of the line that passes through the points (-3, -1)(and (-4, -4)? Put your answer in fully reduced form.

Answers

Answer:

y=3x+8

Step-by-step explanation:

m=3

y-(-1)=3(x-(-3))

y+1=3x+9

y=3x+8

The equation of the line passes through the point (-3, -1)(and (-4, -4) is y=3x+8.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that line passes through the points (-3, -1)(and (-4, -4)

The slope will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -4 + 1 ) / ( -4 + 3 )

Slope = 3

The y-intercept is calculated as,

y = 3x + c

-1 = 3 x -3 + c

c = 8

The equation of the line will be,

y=3x+8

Like others, I have described it to people as broken or fractured English. But I wince when I say that. It has always bothered me that I can think of no way to describe it other than broken, as if it were damaged and needed to be fixed, as if it lacked a certain wholeness and soundness. Ive heard other terms used, limited English, for example. But they seem just as bad, as if everything is limited, including peoples perceptions of the limited English speaker.I know this for a fact, because when I was growing up, my mothers limited English limited my perception of her. I was ashamed of her English. I believed that her English reflected the quality of what she had to say. That is, because she expressed them imperfectly her thoughts were imperfect. And I had plenty of empirical evidence to support me: the fact that people in department stores, at banks, and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.My mother has long realized the limitations of her English as well. When I was fifteen, she used to have me call people on the phone to pretend I was she. In this guise, I was forced to ask for information or even to complain and yell at people who had been rude to her. One time it was a call to her stockbroker in New York. She had cashed out her small portfolio and it just so happened we were going to go to New York the next week, our very first trip outside California. I had to get on the phone and say in an adolescent voice that was not very convincing, This is Mrs. Tan.And my mother was standing in the back whispering loudly, Why he dont send me check, already two weeks late. So mad he lie to me, losing me money.And then I said in perfect English, Yes, Im getting rather concerned. You had agreed to send the check two weeks ago, but it hasnt arrived.Then she began to talk more loudly. What he want, I come to New York tell him front of his boss, you cheating me. And I was trying to calm her down, make her be quiet, while telling the stockbroker, I cant tolerate any more excuses. If I dont receive the check immediately, I am going to have to speak to your manager when Im in New York next week. And sure enough, the following week there we were in front of this astonished stockbroker, and I was sitting there red-faced and quiet, and my mother, the real Mrs. Tan, was shouting at his boss in her impeccable broken English.What is the overall tone?A.humble and admiringB.cynical and condescendingC.resentful, yet lovingD.critical, yet understandingE.hopeful and nostalgic can someone please help me translate this to english (chinese (simplified) to english) What is the sum of the integers less than 100 that have both 6 and 9 as divisors?
