Answer:
y = 4x-9
Step-by-step explanation:
16x-4y-36 = 0
-4y = -16x+36(subtract 16x from both sides and add 36)\
y = 4x-9(divide both sides by -4)
Answer:
I think they have 2, I could be wrong though
Step-by-step explanation:
Answer:
y=-7x -2
Step-by-step explanation:
use formula to find the equation when you know slope and a point
it is: y-y1 = m(x-x1)
plug in values
y-(-30) = -7(x-4)
y+30 = -7x + 28
- 30 from both sides
y = -7x -2

Answer:
A= 5278.34 in ²
Step-by-step explanation:
A= r² × 3.14 (pi)
Radius = Diameter ÷ 2
82 ÷ 2 = 41
41²= 1681
1681 x 3.14 = 5278.34
hope this helps
