Answer:
r = 8
Step-by-step explanation:
The circumference of a circle is given by :
...(1)
We need to find the value of r when C = 16π
Solving equation (1)
So, the value of r is 8. Hence, the correct option is (b).
The equation is solved by the graphed systems of equations is 7x + 3 = x − 3.
The correct option is C.
Given
Two linear equations that intersect at the point (-1, -4) =(x, y) →x=-1, y=-4.
<h3>What is a system of equations?</h3>Systems of equations are sets of equations where the solution is the intersecting point (s) between the equations.
The equation is solved by the graphed systems of equations is;
7x + 3 = x − 3
Solving for x: Grouping the x's on the left side of the equation:
Subtracting x both sides of the equation:
7x+3-x=x-3-x
6x+3=-3
Subtracting 3 both sides of the equation:
6x+3-3=-3-3
6x=-6
Dividing both sides of the equation by 6:
6x/6=-6/6
Dividing:
x = -1 equal to the intersection at x=-1, then this is the equation.
Hence, the equation is solved by the graphed systems of equations is 7x + 3 = x − 3.
