Answer:
0
Step-by-step explanation:
To find the slope, we use the formula
m= (y2-y1)/(x2-x1)
= (6-6)/(-2-4)
= 0/-6
=0
The answer is C...........
Answer:
12
Step-by-step explanation:
(x-h)^2 + (y-k)^2 = r^2 so taking the square root of 144 gives you 12
Answer: 1
Step-by-step explanation:
Answer:
--3 ±sqrt((-3)^2 -4(4)(-9))
-------------------------------
2(4)
Step-by-step explanation:
4x^2-5=3x+4
We need to get this in standard form to answer the question
Subtract 3x from each side
4x^2-3x-5=3x-3x+4
4x^2-3x-5=+4
Subtract 4 from each side
4x^2-3x-9 =0
a = 4
b = -3
c = -9
-b ±sqrt(b^2 -4ac)
---------------------------
2a
--3 ±sqrt((-3)^2 -4(4)(-9))
-------------------------------
2(4)
