Answer:
The center is the point (3,1) and the radius is 3 units
Step-by-step explanation:
we know that
The equation of a circle in standard form is equal to
we have
Convert to standard form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square twice. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
The center is the point (3,1) and the radius is 3 units
Answer: It’s A
Step-by-step explanation: C= -14/3 which is simplified to -4 2/3
Answer:
a=-5
Step-by-step explanation:
divide both sides by -2: -5=a
a=-5
Given: the points (1|2) and (0|3) lie on the line.
Question: equation of the line.
Solution:
General equation of a line: y = kx+d,
whereby:
the point (y|x) lies on the line
When x = 0, y = d
The point (0|3) says that d = 3.
So far, the equation is y = kx +3 ……… (1)
Inserting the point (1|2) into (1):
2 = k(1) + 3 => 2–3=k => -1 = k
Putting k into (1):
y = -1x + 3 => y = -x + 3 => y = 3 - x
Answer:
y = 3 - x
The answer is she puts 4 seeds on each loaf. To get the answer (amount of seeds per loaf), you have to divide 12 by 3, which is obviously 4. Good luck! hope you get a good grade on your homework! :)
