Answer:
The equation of a circle having the center (a, b) and radius r could be formulated by:
(x - a)^2 + (y - b)^2 = r^2
A circle, which has equation form: (x + 3) ^ 2 + y ^ 2 = 81, can be turned into:
(x - -3)^2 + (y - 0)^2 = 9^2
=> center (-3, 0)
=> radius = 9
=> Option 1 is correct
=> Option 4 is correct
=> Option 7 is correct
Hope this helps!

Answer:
x = 5, x = 1
Step-by-step explanation:
Hello!
We can solve this quadratic by factoring.
<h3>
Solve</h3>
Use the zero product property:
- x - 5 = 0
x = 5 - x - 1 = 0
x = 1
x = 5, or x = 1
Answer:
the first one is 12
the second one is 5
Step-by-step explanation:
just work it out you go 7+5=12
and 6-1=5
Answer:
x < −60
Step-by-step explanation:
<em><u>Step 1: Add 10 to both sides.</u></em>
−0.4x−10+10>14+10
−0.4x>24
<em><u>Step 2: Divide both sides by -0.4.</u></em>
−0.4x / −0.4 > 24 / −0.4
x<−60
Answer: w x h = Area
Step-by-step explanation:
If you had a square and the left and right side was 3, that is the width. Then, if you have on the top and bottom lines, that is the height. You multiply one of the widths (3) and one of the heights (3) and in this case you would get:
w x h = area
3 x 3 = 9
Area= 9
