What is the center and radius of the circle? *<br> x² – 2x + 5+ y² = 8
wolverine [178]

Answer: center (1;0), radius = 2

Step-by-step explanation:

x² – 2x + 5+ y² = 8

x² – 2x + 5+ y² = x² – 2x + 1 + 4 + y² = (х-1)² +4 + y²

(х-1)² +4 + y² = 8

(х-1)² + y² = 8 - 4 = 4

(х-1)² + y² = 2²

center (1;0), radius = 2

The temperature in Miami, Florida is 22 degrees warmer than three times the temperature in Bangor, Maine. The temperature in Mia
Nastasia [14]

Answer:

y=\frac{x-22}{3} ; y=20

Step-by-step explanation:

Let Temperature of Maimi T_{m}  and that of Bangor be T_{b}

Given in the condition is T_{m} is 22 more than 3 times  T_{b}

i.e. T_{m} = 22+ 3 * T_{b}

Hence

T_{m} - 22 = 3 * T_{b}

T_{b} = \frac{T_{m}-22}{3}

Here also we are given that T_{m}=82

T_{b} = \frac{82-22}{3}

T_{b} = \frac{60}{3}

T_{b} = 20
