Solve the system of equations below by graphing both equations with a pencil and paper. What is the solution?
y = x+1
y - 2x+3
A. (4,5)
B. (-2,1)
C. (2,3)
D. (-4,-3)

(2/3,5/3)

Step-by-step explanation:

y= 5/3

x=2/3

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
