Does y=2x+5 line goes downwards from left to right?
o y= 2х +5
Оy= 2х – в
oy= 2х
Оy= -2х + 20

in steps

Step-by-step explanation:

when slope is negative line goes downwards from left to right

only y = -2x + 20 has slope -2

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

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
