Step-by-step explanation:
AC+CB+BA=180
2x+23+3x-8+4x+1=180
9x+16=180
9x=180-16
9x=164
x=164/9
x=18.2
Answer:
B
Step-by-step explanation:
the more people who would've surveyed then the graph would be at the same rate.
4-(

)+111
=4-(4)+111
=111 since 4 and -4 cancel each other out
Answer:
m=0.25
Step-by-step explanation:
m = (y_2-y_1)/ (x_2-x_1)
Let's get 2 of any coordinates in the graph, for example: (4,2) and (0,1)
m = (1-2)/(0-4) = 1/4 or 0.25
