The solution of a system, in graphic terms, is where the lines intersect. Ordered pairs follow this form (x,y). Note that all x values are on the horizontal line (think of running when you think of x) and all y values are on the vertical line (think of jumping when you think of y).
According to the graph, y is 0 since the inserect is directly on the x-axis. So (-,0). Cross out A and C because these answer choices do not have '0' as their y-value. This leaves (1/2,0) or (1/3,0). The answer that seems most likely is D. 0.5 (1/2) is closer to 1, and can rounded to 1, opposed to 0.3 (rounded 1/3) The point of solution seems close to one.
Hi there
Total cost of job=
Retail price of goods+labor cost+OH
First find the labor cost
Labor cost=worker A+worker B+worker C
Worker A=13×1.5=19.5
Worker b=9.5×(1+3÷4)=16.63
Worker C=5×(2+3÷4)=13.75
Total labor cost
=19.5+16.63+13.75=49.88
Overhead cost49.88×0.75=37.41
Total cost of job is
74.5+49.88+37.41=161.79
So it's option d
Hope it helps
Answer:
Step-by-step explanation:
<u>Use slope formula:</u>
1) Points (1, 2) and (5, 4)
- m = (4 - 2)/(5 - 1) = 2/4 = 1/2
2) Points (1, -5) and (3, 5)
- m = (5 - (-5))/(3 - 1) = 10/2 = 5
3) Points (2, 3) and (-1, 6)
- m = (6 - 3)/(-1 - 2) = 3/-3 = -1
- Slope is negative, so function is decreasing
4) Points (4, 2) and (-2, 2)
- m = (2 - 2)/(-2-4) = 0/-6 = 0
Answer:
Then you don't change the sign.
Two like signs become a positive sign.
Two unlike signs become a negative sign.
