The slope is undefined because it is a vertical line on the x axis at 0. Its a straight line going up
The sequence is alternatingly decreasing and increasing.
3 - 9 = -6
-6 + 18 = 12
12 - 8 = 4
4 + 16 = 20
Therefore, next term will be:
20 - 7 = 13
Answer:
B. 152 + 7
Step-by-step explanation:
(8x + 16) + (7x - 9)
8x + 16 + 7x - 9
15x + 16 - 9
15x + 7
None of these options have this answer, so we see A and B:
A. x + 7
B. 152 + 7
It can't be A because we have 15x and A is x + 7
By process of elimination we have B. 152 + 7
x = 10 and 2/15
So your variable are these
x= # of accountants
x+10= # of supervisors
4(x+10)= # of mechanics
So you get the equation x+ (x+10) + (4x+40) = 230
and you solve for x
6x + 50 = 230
6x = 180
x=30
so accountants = 30
supervisors = 40
Mecahnics = 160
