7(y^2) = 925.75 (divide both sides by seven)
(y^2) = 132.25 (take the square root of both sides)
y = 11.5 or y = -11.5

What is the product of (2x-7y)(x y)?
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
How do you solve x-7y equals 18 2x-7y equals 22?
x - 7y = 18 ... (A) 2x - 7y = 22 ... (B) Equation (B) - equation (A) gives x = 4 Substituting this value of x in equation (A) gives 4 - 7y = 18 or 7y = -14 which gives y = -2 Solution: (x, y) = (4, -2)
How do you solve 10x-7y equals -6 5x plus 7y equals 81 in an order pair?
10x-7y = -6 5x+7y = 81 Add both equations to eliminate y: 15x = 75 Divide both sides by 15 to find the value of x: x = 5 Substitute the value of x into the original equations to find the value of y: Therefore: x = 5 and y = 8
6x plus 7y equals 96 6x - 7y equals 12?

What is 4 equals 25-7y?
4 = 25 - 7y if you need the value of y, transpose -7y to the left side (it will become 7y). transpose 4 to the right side (it will become -4) here it is: 7y = 25-4 7y = 21 divide both sides by 7. y = 3 that's all.
What is the product of (2x-7y)(x y)?
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
How do you factor 49y squared minus z squared?
This is a difference of two sqaures. 49y2 - z2 = (7y - z)(7y + z)
What is the factor ofsixteen x squared-fortynine y squared?
(4x - 7y)(4x + 7y)
What is the value of y if 5y plus 8 equals 7y?
5y+8=7y 2y=8 y=4
What is the factor of 49y squared - 4?
(7y + 2)(7y - 2)
What is the value of x if y equals x-2 and 7y-4x equals 10?
If: y = x -2 and 7y -4x = 10 Then: x = 8 and y = 6
How do you solve x-7y equals 18 2x-7y equals 22?
x - 7y = 18 ... (A) 2x - 7y = 22 ... (B) Equation (B) - equation (A) gives x = 4 Substituting this value of x in equation (A) gives 4 - 7y = 18 or 7y = -14 which gives y = -2 Solution: (x, y) = (4, -2)
What is y times 7y?
Yx7y = 7y2 (squared )
How do you solve 10x-7y equals -6 5x plus 7y equals 81 in an order pair?
10x-7y = -6 5x+7y = 81 Add both equations to eliminate y: 15x = 75 Divide both sides by 15 to find the value of x: x = 5 Substitute the value of x into the original equations to find the value of y: Therefore: x = 5 and y = 8
