Answer:
5, -9
Step-by-step explanation:
(x - 5)(x + 9) = 0 These are factors, to get the roots, just set each one equal to zero
x - 5 = 0
x = 5
x + 9 = 0
x = -9
The solutions to the system of equations are (-2,-6) and (4,6)
<h3>How to determine the system of equations?</h3>
We have:
-2x + y = -2

Next, we plot the graph of both functions.
From the attached graph, the equations intersect at (-2,-6) and (4,6)
Hence, the solutions to the system of equations are (-2,-6) and (4,6)

The radius is 4.9 and the Circumference is 9.8π
Step-by-step explanation:
<u>Data:</u>
Diameter = 9.8
Circumference = ?
Radius = ?
<u>Radius</u>
Radius is half of the diameter so radius = 
Radius =
Radius = 4.9
<u>Circumference</u>
Circumference = 2πr
Circumference = 2π(4.9)
Circumference = 9.8π
Therefore, the radius is 4.9 and the Circumference is 9.8π
