Weegy: The answer would be y = 2 (x+2). User: px + qy = r 2px - qy = 2r When solving this system of equations, x = Weegy: If r = px + qy and 2px - qy = 2r then.. 2px - qy = 2 (px + qy) 2px - qy = 2px + 2qy - > - qy = 2qy - - > qy = 0 If qy = 0 then 2px = 2r and px = r User: 3x + 2y = 4 2x - y = 5 This system of equations has no solution. has one solution. is coincident. User: John made a rectangle pen for his dog using 28 feet of fencing. If the width of the pen is 2 feet more than one-half the length, what is the length and width of the pen? The length of the pen is Weegy: The length of the pen is 6 feet User: Find the slope of the line whose equation is 2x - 3y + 6 = 0. Weegy: The slope of the perpendicular line would be 3/2. User: One number is 6 more than twice another. If their sum is 51, find the numbers. Which of the following systems of equations represents the word problem? User: One number is 6 more than twice another. If their sum is 51, find the numbers. Which of the following systems of equations represents the word problem? y = 2x + 6 and y = x + 51 y = 2x + 6 and x + y = 51 y = 2(x + 6) and x + y = 51 Weegy: This is an easy mathematical problem. In order to find the slope and the Y intercept of the equation all you need to do is bring the equation in the general form, y = mx + c. It will become y = 2x - 5. [ [ In this case as we can see 2 is the slope and -5 is the y intercept. ] ] User: 2x - y = 10 y = -x - 1 Solve the system of equations Weegy: x=-1/7 and y=-23/7 User: 5x + 10y = 18 x = y - 6 Which of the following equations is the result of substituting y - 6 in for x in the first equation?
