a system of linear equations is graphed.

which ordered pair is the best estimate for the solution to the system?

a. (2, −6.5)

b. (0, −6.5)

c. (−1.5, 0)

d. (2.5, −6.5)

Option A

Step-by-step explanation:

we know that

The solution of the system is the intersection point both graphs

The x-coordinate of the intersection point  is

The y-coordinate of the intersection point belong to the interval--->

see the attached figure to better understand the problem

therefore

the best estimate for the solution to the system is the point

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

a)(x-2)^2+(y-1)^2=9
