Answer:
A
Step-by-step explanation:
- The distance to the problem is 0.8.
Answer:
x = 11
Step-by-step explanation:
1/2(x-14)+11=1/2x-(x-4)
Distribute left half
1/2x-7=1/2x-(x-4)
Distribute right half
1/2x-7=1/2x-x+4
Combine like terms
1/2x-7=-1/2x+4
Add 1/2x
x-7=4
Add 7
x = 11

Answer:
(0, -3)
Step-by-step explanation:
Here we'll rewrite x^2+y^2+6y-72=0 using "completing the square."
Rearranging x^2+y^2+6y-72=0, we get x^2 + y^2 + 6y = 72.
x^2 is already a perfect square. Focus on rewriting y^2 + 6y as the square of a binomial: y^2 + 6y becomes a perfect square if we add 9 and then subtract 9:
x^2 + y^2 + 6y + 9 - 9 = 72:
x^2 + (y + 3)^2 = 81
Comparing this to the standard equation of a circle with center at (h, k) and radius r,
(x - h)^2 + (y - k)^2 = r^2. Then h = 0, k = -3 and r = 9.
The center of the circle is (h, k), or (0, -3).
Answer:
r = -12

<u>Step 1: Define</u>
6 + 18r = 20r - 18 - 4r
<u>Step 2: Solve for </u><em><u>r</u></em>
- Combine like terms: 18r + 6 = 16r - 18
- Subtract 16r on both sides: 2r + 6 = -18
- Isolate <em>r</em> term: 2r = -24
- Isolate <em>r</em>: r = -12
Answer:
26/76 or 0.346 is the answer
