Answer:
center = (-2, 6)
radius = 6
Step-by-step explanation:
<u>Equation of a circle</u>
(where (a, b) is the center and r is the radius)
Therefore, we need to rewrite the given equation into the standard form of an equation of a circle.
Given equation:
Collect like terms and subtract 4 from both sides:
Complete the square for both variables by adding the square of half of the coefficient of and to both sides:
Factor both variables:
Therefore:
- center = (-2, 6)
- radius = √36 = 6
answer: x > - 1.25
Step-by-step explanation:
0.2 •(x + 20)- 3> -7- 6.2x
0.2x + 1> - 7 - 6.2x
