The equation of any circle is
(x - a)^2 + (y - b)^2 = radius^2 where our center is (a, b)
Therefore, our equation is as follows.
(x + 2)^2 + (y - 3)^2 = 16
Sarah scored 82 points on her first test of the year. On the second test,

Answer:
x=0.450765 or x=−0.950765
Step-by-step explanation:
14x² + 7x - 6
→ Find the product, sum and factors
Product = -6
Sum = 7
Factors = No factors
→ Since there are no factors utilise the quadratic formula
→ List the values of a, b and c
a = 14
b = 7
c= -6
→ Substitute into the formula
→ Simplify
x=0.450765 or x=−0.950765
Integers are numbers and absolute value is the magnitude of the numbe non dependent of its sign (absolute value is the number as a positive) ex; the absolute value of -3 is 3... and if the original number is positive it stays the same so ex; the abosolute value of 8 is 8
