6x² - x - 15

Rewrite the expression by writing -x as a difference:

6x² + 9x - 10x - 15

Factor out 3x from the expression:

3x * (2x + 3) - 10x - 15

Factor out -5 from the expression:

3x * (2x + 3) - 5 * (2x + 3)

Factor out the expression:

(2x + 3) * (3x - 5)



Therefore the answer to your question would be:

D) 3x - 5

Find an equation of the line in the form whose​ x-intercept is 15 and​ y-intercept is 3​, where​ a, b, and c are integers with n
madreJ [45]

x-intercept = (15, 0)                  y-intercept = (0, 3)

slope (m) = (y₂ - y₁)/(x₂ - x₁) = (0 - 3)/(15 - 0) = -3/15 = -1/5

Point-Slope formula: y - y₁ = m(x - x₁)   ; where (x₁, y₁) is one of the given points

y - 0 = (-1/5)(x - 15)

    -5y = x - 15

             x + 5y = 15

Answer: x + 5y = 15
