No the don't add up to one eighty I'm pretty sure if not tell me
Answer:
where is the question.......?
Answer:
y= 1/3x - 1
Step-by-step explanation:
1/3 is slope so m and -1 is the y-intercept
That would be 9% of 15.....turn ur percent to a decimal..." of " means multiply
0.09(15) = $ 1.35 sales tax <==
The standard equation of the circle is x² + y² + 8x - 9 = 0 if the circle with center at (-1,-4) that passes through the point (-4,0).
According to the question,
The circle with center at (-1,-4) that passes through the point (-4,0).
To find the radius of the circle:
Radius r = √[(-4 - (-1))² + (0- (-4))²]
=√(-4+1)² + (4)²
=√9+16
=√25
=5.
In order to find the standard equation of the circle is
(x - (-4))² + (y - (0))² = (5)²
(x + 4)² + (y )² = 25
x² + 8x + 16 + y² = 25
x² + y² + 8x + 16 = 25
x² + y² + 8x = 25 - 16
x² + y² + 8x = 9
x² + y² + 8x - 9 = 0
Hence, the standard equation of the circle is x² + y² + 8x - 9 = 0.
