Vera claimed the solution set on the number line represents the inequality negative 78. greater-than-or-equal-to x. a number line going from negative 82 to negative 78. a closed circle is at negative 79. everything to the left of the circle is shaded. which error did vera make? vera wrote the inequality with the variable on the left side of the relation symbol. vera wrote a relation symbol that does not represent the direction of the ray. vera selected an inequality that does not include –79 in its solution set. vera used the wrong number in her inequality.

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

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

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
