This is a "linear equation" problem. There is only one variable, the amount of time spent on the repair. Everyone is charged the uniform charge just for bringing it in. so let's set this up: 2 hrs.=$100 1.5 hrs.=$80 I say, let y = the total cast of a TV repair, x = the number of hours spent on repairing the TV, m = the rate that is charge per hours worked, and b = the uniform charge: y = mx+b (total cost = the hourly rate times the number of hours worked plus that funky charge everyone has to pay) a.) This is just asking us to fill in the numbers: $100=m(2hr)+b $80=m(1.5hr)+b b.) this is the slightly trickier one. Unless you have to show your work, you could just look at the difference in hours worked and the difference in total cost and see the rate: $100-$80=$20 2hr-1.5hr=.5hr so we reason that a half-hour difference costs $20 more, so a full hour costs $40. This means m= $40/hr. We then use either or both equations to find b. $100=($40/hr)(2hr) + b $100=$80 + b $100-$80= b b=$20 And now the equation read: y=($40)x + $20 The question was how much 3 hrs costs. So, let x=3 y=($40)(3) + $20 y=$120 + $20 y=$140 c.) we went over this one. x represents the number of hours works repairing the TV that I broke because I sent my Wii remote into it. d.) the constant would be the one factor in this equation that never changes, the one charge everyone is going to pay, that weird uniform charge of $20. I hope this helps.

Well, if the side you're looking for is the hypotenuse, this is how you do it. You really would have to use the Pythagorean Theorem (it really is the easiest way). 350 squared + 245 squared = x squared 122,500+60,025= x squared x squared = 182,525 x= about 427.22944 If the remaining side is a leg, you would just put the other values in the equation and solve (a squared +b squared = c squared)

QUESTION 1:for each graph, find the length of segment AB to the nearest tenth. i can't show you the graph but A is (-9,-6) and B is (6,6). How do i find the lenght of segment AB?????? QUESTION 2: there's a diagram of 2 segments. go to the link for the diagram http://i34.tinypic.com/148df7t.jpg. the question is MB=8x +7, AB=126, solve for x. for both questions please show me how to get the answer thanks! best question gets 10 pts
Homework help. Geometry, Apothems...?
Ok so heres the problem: The apothem of a regular pentagon is 10.8cm. a) Find the radius of the circumscribed circle. b) What is the length of a side of the pentagon. c) Find the perimeter of the pentagon. This is a review question from last years geometry and its got me totally confused. Btw incase anyone can't remember (I couldn't) an apothem is the measure of a line of the segment from the center of the polygon to the midpoint of one of its sides.
