Step-by-step explanation:
6k + 12 + 9=9
6k + 12 = 9 - 9
6k + 12 = 0
12 = -6k
12/-6 = -6k/-6
2/-1 = k
k = -2
--------------------------------------------------
Find Slope :
--------------------------------------------------
y = -2/7x + 9
Slope = -2/7
Perpendicular slope= 7/2
--------------------------------------------------
Find y - intercept :
--------------------------------------------------
y = mx + b
y = 7/2 x + b
At (4, -6)
-6 = 7/2 (4) + b
-6 = 14 + b
b = -6 - 14
b = -20
--------------------------------------------------
Form equation :
--------------------------------------------------
y = mx + b
y = 7/2 x - 20
2y = 7x - 40
--------------------------------------------------
Answer: 2y = 7x - 40
--------------------------------------------------

I attached a picture of my work and I stuck it into my calculator to check it
Answer:
-5x^2 +14x +24
Step-by-step explanation:
(x-4)(-5x - 6)
FOIL
first : x*-5x = -5x^2
outer : -6x
inner: -4*-5x = 20x
last: -4*-6 = 24
Add them together
-5x^2 -6x+20x +24
-5x^2 +14x +24
