Ight now, ivy is half as old as her sister, rose. in six years, ivy will be two-thirds as old as rose. how old are the sisters right now? write a linear equation (hopefully in one variable) that could be used to solve this problem. (2pts) define your variable(s). (1pt) solve the equation for the variable that you have chosen. you need not show your work. (1pt) respond to the question. (1pt)

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

x = 23.78

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
