Sylvie finds the solution to the system of equations by graphing. y = x + 1 and y = x – 1 Which graph shows the solution to Sylv
ie’s system of equations?
1 answer:
Graphs of y = x+- 1 and of y = x - 1 are shown in the figure below.
The intersection of the two graphs is the solution for the two equations.
Answer:
There is no solution.
Explanation:
It is clear that the two lines are parallel and will never intersect.
Note that the equation for a straight line is of the form
y = mx + b
where
m = slope,
b = y-intercept.
y = x + 1 has slope of m=1.
y = x - 1 has slope of m=1.
The two slopes are equal.
Because parallel lines do not intercept, there is no solution.

Answer:
No.
Step-by-step explanation:
The equipment wll save $35,000 per over for 10 years, which totals to $350,000.
If the equipment is bought on a simple interest rate of 12% annually for ten years, it will cost:
We will need to pay $440,000 in total for the machine in over ten years.
If we compare both values, it can be deduced that industrial equipment is more expensive than labor cost.
