The first three steps in determining the solution set of the system of equations, y = x2 - 2x + 8 and y = 2x + 11, algebraically
are shown in the table.
step
step 1
step 2
step 3
equation
-x° -2x+8 - 2x+11
0 - x² + 4x+3
0-(x + 1)(x+3)
which represents the solution(s) of this system of equations?
(-3,-1)
(-3,5)
(-3,5) and (-1,9)
(1, 13) and (3, 20)

(-3,5) and (-1,9)

Step-by-step explanation:

x+1 = 0              ;   x + 3=0

x = -1                 ;    x = -3

y = 2*-1 +11       ;   y = 2*-3 +11

y = -2+11 = 9    ; y = -6 +11 =5

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
