Y_Kistochka [10]

Answer:

The answer to your question is below

Step-by-step explanation:

To solve this problem, for a and c, just look in the x-axis the value given and find the value of a and c in the y-axis.

To solve this problem, for b and d, just look in the y-axis the value given and find the value of b and d in the x-axis.

f(2) = -3    a = -3

f(b) = 0      b = -4

f(-2) = -1     c = -1

f(d) = -6     d = 8

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)
