Answer:

quadratic

Step-by-step explanation:

Given

x²y - 2xy - 24y ← factor out y from each term

= y(x² - 2x - 24) ← quadratic factor

To factor the quadratic

Consider the factors of the constant term ( - 24) which sum to give the coefficient of the x- term (- 2)

The factors are - 6 and + 4, since

- 6 × 4 = - 24 and - 6 + 4 = - 2, hence

x² - 2x - 24 = (x - 6)(x + 4) and

x²y - 2xy - 24y = y(x - 6)(x + 4) ← in factored form

Find the equation of the line The line has a slope of 1.3 and passes through the point (-2.3, -3.2)

irga5000 [103]

Answer:

y=1.3 x - 0.21

Step-by-step explanation:

$y = (slope) \times x + (constant)$

set (-2.3,-3.2) in above

$- 3.2 = 1.3 \times ( - 2.3) + c$

then c=-0.21
