Answer:(x + 6) + (y + 2)^2 = 13
Step-by-step explanation:
The centre of the circle is halfway along the diameter = (-6, -2)
r^2 = (-4 - -6)^2 + ( 1 - -2)^2 = 2^2 + 3^2 = 13
So circle equation is (x - -6)^2 + (y - -2)^2 = 13
rotation, then translation, then reflection
Answer:
60
Step-by-step explanation:
Each pendant costs $1.90. The total costs to make the 2 necklaces (beads and pendant) is $10.20. You have to find how much the beads cost for BOTH necklaces so you would solve $3.20 x 2. You would get $6.40. So now you subtract $6.40 from $10.20 to find how much the pendant for both necklaces cost. That would be $3.80 now you just divide by 2 to find the cost of 1 pendant.
