Answer:

-2x^2-5x-3

Step-by-step explanation:

(3x^2 – 3x+6) - (5x^2 + 2x + 9)

Distribute the minus sign

(3x^2 – 3x+6) - 5x^2 - 2x - 9

Combine like terms

3x^2 -5x^2 -3x-2x +6-9

-2x^2-5x-3

Which equation is in point-slope form for the given point and slope?
faust18 [17]

Answer: y-7 = 4(x+3), choice B

============================================

Point slope form is generally

y-y1 = m(x-x1)

we have m as the slope and (x1,y1) as the point this line goes through. In this case,

m = 4

(x1,y1) = (-3,7) so x1 = -3 and y1 = 7

So,

y-y1 = m(x-x1)

y - 7 = 4(x - (-3))

y - 7 = 4(x + 3)

which is why choice B is the answer
