Celina had a rectangular tablecloth with dimensions x feet and 3 feet. She put lace along 4 feet of the edge of the tablecloth.
An expression is shown below:
(2x + 6)  4
Part A: What does the expression represent? (4 points)
Part B: What does 2x + 6 represent? (3 points)
Part C: What does 2x represent? (3 points)

Best ResponseYou've already chosen the best response.1dw:1432939869827:dw you would write: x + x +3 + 3

Best ResponseYou've already chosen the best response.0Yes, so (2x+6) represents the entire perimeter?

anonymous

Best ResponseYou've already chosen the best response.0So does (2x+6)4 represent the area or...?

Z4K4R1Y4

Best ResponseYou've already chosen the best response.1no. (2x + 6) is the entire perimeter...but 4 ft have lace on them.

Best ResponseYou've already chosen the best response.1so what would (2x +6)  4 be?

Best ResponseYou've already chosen the best response.0I'm not sure, but i'd have to guess, its the perimeter minus the lace. im not sure what it is otherwise.

Best ResponseYou've already chosen the best response.0Is there a more detailed way of describing the expression?

Z4K4R1Y4

Best ResponseYou've already chosen the best response.1you're right. it means that's the length of the perimeter that doesn't have lace.

anonymous

Best ResponseYou've already chosen the best response.0Okay i see now, So for part A i'd put Part A: The expression (2x+6)4 represents the part of the perimeter without the lace. Part B: (2x+6) Represents the entire perimeter, x+x being two sides, and 3+3 each being another two sides. Part C: 2x just represents the parallel sides of the rectangle. Also known as the sides opposite to each other, and would basically give its length once x is plugged in.

Best ResponseYou've already chosen the best response.0Okay here i go, Veronica teaches French in groups of four students. She rents a room for $200 per month. She charges $45 per hour per student. Veronica teaches seven groups of students, and her net earnings per month are $6,100. Part A: If each student learns French for the same number of hours, write an equation that can be used to calculate the number of hours each student learns French in a month. (5 points) Part B: How many hours did each student learn French each month? Show your work and justify each step of your work. (5 points)

Best ResponseYou've already chosen the best response.028*45*h=6100+200 28 represents the students 45 represents the cost per hour. h represents the # of hours

Best ResponseYou've already chosen the best response.0@LegendarySadist What do i use that for?

anonymous

Best ResponseYou've already chosen the best response.0It is the answer for Part A and the formula you would use to solve Part B

anonymous

Best ResponseYou've already chosen the best response.0Okay, so i just solve for h, in 28*48h=6,100+200?

anonymous

Best ResponseYou've already chosen the best response.0Honestly I'm not too sure about the "+200" part since I'm not very well acquainted with what "net earning" is referring to. You may or may not need the +200

anonymous

Best ResponseYou've already chosen the best response.0i get 28*48h=6,300 > 225 divded by 48 recieving 4.6875

anonymous

Best ResponseYou've already chosen the best response.0Is that the answer for part b?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0ok, I confirmed the +200, so yeah that should be the answer.

anonymous

Best ResponseYou've already chosen the best response.0but wait would the equation look like this (7)(4)(48)x+200=6,100?

anonymous

Best ResponseYou've already chosen the best response.0instead of the +200 being on the other side

Best ResponseYou've already chosen the best response.0Sam is observing the velocity of a car at different times. After two hours, the velocity of the car is 54 km/h. After four hours, the velocity of the car is 58 km/h. Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the car at different times. Show your work and define the variables used. (5 points) Part B: How can you graph the equation obtained in Part A for the first six hours? (5 points)

Best ResponseYou've already chosen the best response.0Sorry for the delay, but i suppose it would be y=2x+50 wouldn't it? Or just 2x+50

anonymous

Best ResponseYou've already chosen the best response.0Well it satisfies both of them. For x of 2, you would get 54 and an x of 4 would get you 58

anonymous

Best ResponseYou've already chosen the best response.0Okay but isnt that in slope intercept form

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0So X represents the amount of Hours, and Y represents different times???

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Slope intercept form is y=mx+b with m being the slope and b being the yintercept. We have y=2x+52 with 2 being the m and 52 being the b

anonymous

Best ResponseYou've already chosen the best response.0How can we put that in standard form??

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Oh, didn't notice that =(

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0does it being in slope intercept form change our entire equation? or can we just switch it to standard? also what do the X and Y variables represent

anonymous

Best ResponseYou've already chosen the best response.0I'd think it would just be 2x+y=50

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0But honestly I'm not sure

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Okay and x represents the velocity while y represents time? in other words we could do 2v+t=50???

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Standard form is just so useless that i never use it and don't remember how to convert.

anonymous

Best ResponseYou've already chosen the best response.0Okay well how would i answer for part A: and B:????

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Actually yeah, just graphed them and they both fit so 2v+t=50 would be it

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0For part A do i put Part A: 2v+t=50 If you input 2 for velocity or 4 both satisfy what is given in the primary equation. v represents the velocity, while t represents time. To solve for v just add it to the other side > t=+2(2)+50 > t=54, then you could switch out 4 for v receiving 58. Part B: To graph, just plug in 0 for t and then 6 for t...you get (0,50) and (6,62) Connect those 2 points and you have your graph for the first 6 hours

Best ResponseYou've already chosen the best response.0The table below shows the outputs y for different inputs x: Input (x) 1 1 3 3 Output (y) 4 2 12 6 Part A: Does the table represent y as a function of x? Justify your answer. (5 points) Part B: The total cost f(x), in dollars, for renting a paddleboat for x hours is shown below: f(x) = 20 + 10x What is the value of f(120), and what does f(120) represent? (5 points)

anonymous

Best ResponseYou've already chosen the best response.0I believe for Part a it would be Part A: No the GRAPH does NOT represent a function being there are more than one of the same x variable. But im not sure for part B

anonymous

Best ResponseYou've already chosen the best response.0Sorry i meant the table not graph

anonymous

Best ResponseYou've already chosen the best response.0Wait, the input of 1 has two outputs? Definitely not a function there.

anonymous

Best ResponseYou've already chosen the best response.0Yea, but i dont understand part B.

anonymous

Best ResponseYou've already chosen the best response.0Just put 120 for x so f(x)=20+10(120)

anonymous

Best ResponseYou've already chosen the best response.0Okay and what does that represent???

anonymous
