Draw a graph of the circle with equation x²+y²=9.What are the solutions to the system of circle and line when the circle is give
aleksandrvk [35]

Answer:

(-2.23606, 2) and (2.23606, 2)

Step-by-step explanation:

x^2+y^2=9

y=2

The circle has its center situated at the origin and radius of 3 units

Applying the value of y to the first equation

x^2+2^2=9

\Rightarrow x^2=9-4

\Rightarrow x^2=5

\Rightarrow x=\sqrt{5}

\Rightarrow x=\pm 2.23606

So, the points where the line will intersect the circle is (-2.23606, 2) and (2.23606, 2)

Tom and his friend are driving to Tameka is taking the same 432-mile round trip as Tom to Louisville, but renting a car at a spe
timurjin [86]

Answer: The correct answer is $ 134.42 for the gas and the rental.

Step-by-step explanation: The trip is 432 miles and Tameka's car gets 35 miles to the gallon. So we have to figure out how many gallons we would use for the entire trip by dividing 432 by 35= 12.34 gallons of gas.

We know gas is $2.79 a gallon so we multiply 2.79 (cost per gallon) x 12.34 ( our total gallons used) =$34.43 in gasoline.

The rental costs $99.99 so we add that cost and the cost of the gas $34.43= $134.42 the total cost of the rental and the gas.
