Weegy: 1/15 right because 1/3 is the chance and there is five so 3 times five is 15

(x + 1)(x - 5) = -9
x^2 - 5x + x - 5 = -9
x^2 - 4x + 4 = 0
(x - 2)^2 = 0
x - 2 = 0

If (x + 1)(x - 5) = -9, then the true statements is: x - 2 = 0.

t Object]User: x + y = k x - y = k The solution to the system shown is _____. (0, k) (2, 2) (k, 0)
Weegy: Let's use the reduction method by adding them up, you'll cancel out the y's, leaving you with x=k Now if x=k, let's replace k by x x-y=k x-y=x x-x=y 0=y Since x = k and 0 = y, [ we'll say that the solution to this system is (K,0) ] User: 3x - 4y = 7 3x + 2y = -5 When the second equation is subtracted from the first, the resulting equation is _____. -6y = -12 -6y = 12 -2y = -12 2y = 12 Weegy: -6y = 12 User: 5x + y = 6 5x + 3y = -4 The y-coordinate of the solution to the system shown is ___. -5 -1 1 Weegy: that would be -5 User: Given the system of equations, what is the x-coordinate of the solution? y = 3 - 1/2x 3x + 4y = 1 22 -17/2 -11 (More)

t Object]User: A boat makes a 120-mile trip downstream in 3 hours but makes the return trip in 4 hours. What is the rate of the current? 3 mph 4 mph 5 mph User: Solve the system algebraically. 3x - 2y - 1 = 0 y = 5x + 4 What is the solution? {(-9/7,-17/7)} {(9/7,17/7)} {(9/7,-17/7)}
Weegy: Y = 5X + 4 since: 3X - 2Y - 1 = 0 3X - 2(5X + 4) - 1 = 0 3X - 10X - 8 - 1 = 0 -7X - 9 = 0 so: X = - 9/7 Y = 5( - 9/7 ) + 4 Y = - 45/7 + 28/7 = - 17/7 answer is A.{(-9/7,-17/7)} User: 2x - y = 5 x + 3y = 7 What is the value of the y-determinant? 7 9 22 Weegy: Did you mean the determinant of coefficients? 2 -1 1 3 determinant = 2(3) - (-1)(1) = 6+1=7 source: yahoo User: The system shown has _____ solution(s). y = 1/2x + 1 2y - x = 2 no one infinite User: Which of the following equations is equivalent to 1/2x - 2/3y = 5? x - 2y = 30 4x - 3y = 30 3x - 4y = 30 Weegy: 3x - 4y = 30 User: 2x - y = 5 x + 3y = 7 What is the second row of entries for the system determinant? 0, 3 1, 3 3, 7 Weegy: Did you mean the determinant of coefficients? 2 -1 1 3 determinant = 2(3) - (-1)(1) = 6+1=7 source: yahoo User: A boat makes a 120-mile trip downstream in 3 hours but makes the return trip in 4 hours. If b = the rate of the boat in still water and c = the rate of the current, which of the following equations represents the trip upstream? 3(b - c) = 120 4(b - c) = 120 4(b + c) = 120 Weegy: A.3(b - c) = 120 User: In a certain clothing store, 6 shirts and 3 ties cost $79.50, and 3 shirts and 2 ties cost $41. Determine the cost of each shirt. $10.00 $11.00 $12.00 Weegy: 3s + 5t = 60 ......(1) 2s + 3t = 39 ......(2) (1)*2 - (2)*3: t = 3, s = (39 - 3t)/2 = 15 Answer: Shirts cost $12 each, and ties cost $3 each. User: Solve the system algebraically. Check your work. 5x + 2y = 10 3x + 2y = 6 Make sure there are NO SPACES in your answer. Be sure to include a comma. Weegy: The solution for 5x + 2y = 10, 3x + 2y = 6 is (2, 0) (the value of x is 2 and the value of y is zero) User: In which of the following data sets is the mean equal to the mode? 4, 4, 4, 6, 6 4, 5, 5, 5, 6 3, 3, 4, 6, 7 Weegy: 4, 5, 5, 5, 6 is data set where the mean is equal to the mode.

What is plagiarism?
Weegy: Plagiarism is getting the work of someone else and claim it as your own. It is a big no-no in university life and it could mean expulsion. [ Sometimes people just get to tired to search and discover for themselves that they actually steal someone's idea to save their butts. How hard can it be? considering all the innovation that we have today in terms of researching. It's a big lie when we say that everything that can be discovered already exists. On the contrary, there are a lot of things that we need to know. The world continuously moves and everything changes. Don't think you can't be caught when you plagiarize. Cheaters never win. ] User: What are the consequences of plagiarism? Weegy: The major consequence of plagiarism is that people who engage in it hurt themselves. [ Good research and writing involve a host of skills: for a start, evaluating sources, taking careful notes, selecting appropriate quotations, paraphrasing, and giving credit to others for their ideas and words. Students who plagiarize may never learn these skills, and life in college and beyond can be difficult without them. ] User: Plagiarism damages reputations and relationships. True False (More)
