The distance between point A and point B is 2 1/2 units. Which number could represent point B? A)-30. B)2.5. C)-2.0. D)3.5

C- -2.0

Step-by-step explanation:

Counting 2 1/2 to the right makes 3, but that is not one of the answer choices, so we should count to the left 2 1/2 units and then we get -2.0, which is C.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

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
