Answer:
81 F
Step-by-step explanation:
Hours | Temp.
0 | 75F
1 | 77F
2 | 79F
3 | 81F
8(3) - 3y = 12
First, multiply 8 × 3 to get 24.
Second, subtract '24' from both sides.
Third, subtract '12 - 24' to get '-12'.
Fourth, divide both sides by '-3'.
Fifth, change the whole fraction to a negative.
Sixth, 12 ÷ 3 = 4. Simplify your fraction to 4.

Answer: Banana has the lowest value, and habanero has the greatest value
Step-by-step explanation:
Complete the square:
<em>x</em> ^2 - 2<em>x</em> + <em>y</em> ^2 + 4<em>y</em> + 1 = 0
(<em>x</em> - 1)^2 + (<em>y</em> + 2)^2 + 1 = 1 + 4
(<em>x</em> - 1)^2 + (<em>y</em> + 2)^2 = 4 = 2^2
Hence the center is (1, -2) and the radius is 2. (D)
