You are asked to solve the inequality (x+3)(x-4)<7: (1) Suppose that you incorrectly begin by solving x+3=7 and x-4=7. You will get two values for x; x=-3 and x=4. These you might suppose to be the upper and lower bounds for the inequality. Thus you might get -3<x<4 as an answer. All numbers in this range are indeed solutions, but not every solution is in the interval. For instance, 4.5 is a solution since...http://www.enotes.com/homework-help/referring-what-you-have-learned-you-will-solve-472692Sun, 23 Nov 2014 02:37:13 PSTReferring to what you have learned, you will solve this inequality: (x...

Referring to what you have learned, you will solve this inequality: (x + 3)(x – 4) < 7. To solve (x + 3)(x – 4) < 7, start by setting (x + 3) = 7 and (x – 4) = 7. Now solve the two equations. Provide a detailed explanation of why using this method to solve the inequality does not give the correct answer. To show your work, attach a MS Word document to your response. Use Microsoft Equation Editor or a similar tool to help you...http://www.enotes.com/homework-help/referring-what-you-have-learned-you-will-solve-472692#1November 22, 2014, 10:16 pm PSTThis answer translates the 1 is less than or equal to x or better yet x...

This answer translates the 1 is less than or equal to x or better yet x is greater than or equal to 1. The variable is usually on the left but it would never hinder you finding the answer. So if x is greater than 1 or equal to 1, x can only be 1 and numbers greater than one. X can NEVER be a number less than one not even .999999. So x can be number 1,2,...,15, 16,17,... and so on.http://www.enotes.com/homework-help/what-x-1-lt-x-471377Sat, 22 Nov 2014 01:35:14 PST59x2 59 x 2 is equal to 118 However you can look at it from several...

59x2 59 x 2 is equal to 118 However you can look at it from several other ways as well! You can add 59 twice. It will look something like 59+59 which will give you 118. Or if its easier for you to visualize smaller numbers you can think of it as (40+19) + (40+19) or (50x2) + (9x2) which will all give you 118.http://www.enotes.com/homework-help/what-59x2-471049Sat, 22 Nov 2014 01:05:53 PST1) |-6 - 10| Anything that happens to be inside absolute value will...

1) |-6 - 10| Anything that happens to be inside absolute value will always be positive so |-a| will always equal a. So with this question you are going to add the contents inside together since they are both negative. Sometimes it helps for people to see the question asked as -6 + (-10) so the answer will be -16 which is inside absolute value so |-16|= 16 2) 3 + 4(8 (3.5 - 20) - 41) Let's take this problem step by step using Please Excuse My...http://www.enotes.com/homework-help/1-6-10-2-3-4-8-3-5-20-41-3-6-1-8-3-8-4-13-5-3-7-2-470862Sat, 22 Nov 2014 00:30:20 PST1. |-6 - 10| Anything that happens to be inside absolute value will...

1) Michael is only able to work 35 hours a week so you are going to multiple that to the $8.50 that Jan is going to be paying him per hour. Also you are going to add the $20 bonus she pays every week for the position so you will get 8.50(35) + 20= c . C being the total cost of that week. To make it into a 2-week pay period you will multiply the entire equation by 2 so 2 x (8.50(35) + 20) this equation will give you the answer $635 for...http://www.enotes.com/homework-help/1-jan-owns-coffee-shop-she-planning-hire-michael-470812Fri, 21 Nov 2014 21:36:15 PST5x/x-2 -7=10/x-2 Okay so our goal here is find the LCD of the entire...

5x/x-2 -7=10/x-2 Okay so our goal here is find the LCD of the entire equation. The LCD is x-2 which is going to be multiplied on both sides of the equation. x-2(5x/x-2 -7) = (10/x-2) x-2 so you distribute and you will get 5x(x-2)/x-2 -7(x-2) = 10(x-2)/x-2 Now the denominators on both side cancel each other out and you will have 5x -7(x-2) = 10 Now distribute the seven amongst the x-2. 5x -7x +14 =10 Add like terms! -2x + 14 = 10 Now subtract...http://www.enotes.com/homework-help/solve-x-5x-x-2-7-10-x-2-470756Fri, 21 Nov 2014 21:16:49 PSTSo we are going to be using the slope intercept form which is y=mx+b y...

So we are going to be using the slope intercept form which is y=mx+b y and x are going to be your points/ coordinates. m is the slope b is what we are going to be looking for in order to find the equation for the line that passes through the point. So 10 is x and -1 y and m is -2 we are going to substitute these into the equation -1 = -2 x(10) + b So multiply the -2 by the 10 -1 = -20 + b Now add 20 on both sides 19 = b So we are now going to...http://www.enotes.com/homework-help/what-line-passes-through-point-10-1-has-slope-2-471701Fri, 21 Nov 2014 20:30:02 PST-8 - (-8) There is always two ways you can think of this questions 1....

-8 - (-8) There is always two ways you can think of this questions 1. Two negatives always make a positive! the negatives here would be the negative outside of the parentheses and the negative inside the parentheses so -8 - (-8) which will turn the equation into -8+8 = 0 2. The second way to think about it would be to add a 1 out side the paranthese and you will get negative one, -1, to multiply by -8 which will turn the -8 positive which...http://www.enotes.com/homework-help/change-each-subtraction-addition-opposite-number-471754Fri, 21 Nov 2014 20:19:43 PST100 + 5 Why do I love this question so much?

100 + 5 Why do I love this question so much? So back when I was younger my teacher always taught me that if you add a number that has a zero at the end by numbers one through nine that zero will always be the single number it was added to. So 100 of course has a 0 at the end and it is being added by a single number 5. So the answer is 105!http://www.enotes.com/homework-help/100-5-471762Fri, 21 Nov 2014 19:41:31 PSTHence each of each of the five friends will get 4/15 of the...

So we are going to turn Sean and his friends into a fraction 5/1 Now you are going to take the 1 pepperoni pizza and add it with the 11/3 of cheese pizza that is left. You get 2 1/3 but you do not want it in this form you want it as a fraction. So you will take the 2 and multiply by the denominator which the answer will be 6/3 which you will then add to the 1/3. You will get 7/3 as the amount of pizza left that you want to divide amongst the...http://www.enotes.com/homework-help/sean-his-4-friends-wanted-share-remaining-pizza-472434#2Fri, 21 Nov 2014 19:20:15 PSTThe negative numbers are lower than the positive no .

The negative numbers are lower than the positive no . The higher the negative no , the lesser its value . The higher the positive no , the greater the value . Hence the order should be as follows -14, -12, -7, -1, 0, 3, 9, 11, 12 . Starting from -14 as it is the lowest and ending at at 12 as it is the highest . http://www.enotes.com/homework-help/how-do-you-put-these-order-1-12-12-11-7-14-9-3-0-472579Fri, 21 Nov 2014 18:49:17 PST
