User: One number is 3 less than twice another. If their sum is 39, find the numbers. Which of the following systems of equations represents the word problem? y = 2x - 3 and y = x + 39 y = 2x - 3 and x + y = 39 y = 2(x - 3) and x + y = 39

Weegy: x + 2x - 3 = 39 <==EQUATION 3x - 3 = 39 3x = 42 x = 14 2x - 3 = 25 14 and 25 <==ANSWERS Answer: B. y = 2x - 3 and x + y = 39

User: The line that passes through (-1, -3) and (2, 1)

User: Input in standard form the equation of the given line. The line that passes through (-1, -3) and (2, 1)

Weegy: The line that passes through (-1, -3) and (2, 1) is y = 4/3x - 5/3.

User: Input in standard form the equation of the given line. The line that passes through (1, 5) and (-2, 3)

Weegy: The equation of the line that passes through (4,1)and(-2,3) is y = -1/3x + 7/3.

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? 5x + 10y - 6 = 18 5y - 6 + 10y = 18 5y - 30 + 10y = 18

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?

Divide the following polynomials, then place the answer in the proper location on the grid. Write answer in descending powers of x. (27x^4 - 18x^3 + 9x^2) ÷ 3x
Question
Updated 9/12/2014 11:15:06 AM
(27x^4 - 18x^3 + 9x^2) ÷ 3x
= (27x^4/3x) - (18x^3/3x) + (9x^2/3x)
= 9x^3 - 6x^2 + 3x
Divide the following polynomials, then place the answer in the proper location on the grid. Write answer in descending powers of x. (12x3 - 11x2 + 22x - 5) (4x -1)
Question
Updated 9/12/2014 11:13:46 AM
(12x^3 - 11x^2 + 22x - 5) ÷ (4x - 1)
= (12x^3/4x - 1) - (11x^2/4x - 1) + (22x/4x - 1) - (5/4x - 1)
= 3x^2 - 2x + 5

Factor completely, then place the answer in the proper location on the grid. 12a^2 - 36ab + 27b^2
Weegy: 12a^2 - 36ab + 27b^2 = 3(2a - 3b)^2 User: Subtract the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of a. Subtract: 16a 2 - 32a + 9 from 12a 2 + 60a - 8. User: Multiply the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of x. (8x + 3)(4x + 7) Weegy: (8x + 3)(4x + 7) = 32x^2 + 12x + 56x + 21 = 32x^2 + 68x + 21 User: Divide the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of a. Divide 5a^2 + 6a - 9 into 25a^4 + 19a^2 - a - 78. (More)
Question
Updated 9/12/2014 7:54:22 AM
(12a^2 + 60a - 8) - (16a^2 - 32a + 9)
= (12a^2 + 60a - 8) + (-16a^2 + 32a - 9)
= -4a^2 + 92a - 17
Factor completely, then place the answer in the proper location on the grid. 16x4 - 64y8
