Is -9x^(2)-30x-25 a perfect square trinomial?

  no

Step-by-step explanation:

The leading term and constant term of a perfect square trinomial are positive. Here, all terms are negative, so the trinomial is not the square of any binomial with real coefficients.

It can be written in terms of a perfect square as ...

  = -(3x +5)²

answer: idk

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
