Answer:
Solve equations of the form a x 2 + c = 0 by extracting the roots. Extracting roots involves isolating the square and then applying the square root property. After applying the square root property, you have two linear equations that each can be solved.
Step-by-step explanation:
The appropriate relation is ...
... s = rθ
Filling in the given information, you get ...
... 3 ft = r·(1/4)
Multiply by 4 and you find r:
... 12 ft = r
Answer:
x=-7, y=2. (-7, 2).
Step-by-step explanation:
x-y=-9
x+y=-5
-----------
2x=-14
x=-14/2
x=-7
-7-y=-9
y=-7-(-9)
y=-7+9
y=2
Answer:
c = 
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 
m = 
with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (2, c)
m = 
= 
, then
= ( cross- multiply )
2(c - 4) = - 3
2c - 8 = - 3 ( add 8 to both sides )
2c = 5 ( divide both sides by 2 )
c =
