we have
<u>The system of equations</u>
-------> equation 
-------> equation 
Substitute equation
in equation 

subtract
both sides


Divide by
both sides

the solution is the point 
therefore
the answer is
the solution to the system of equations is the point 
To find the number of non-defective chips, we simply use this equation:
2,000 * 4/5
8000/5
Now you simply divide:
1600
1600 chips aren't defective
The y-intercept of the function is +5. The average rate is 1/3. The domain is 20.4 miles/hour.
the answer is
x=8y/3(1-8y)
y=3x/8(1+3x)
hope this helped l used cymath to solve this problem.
good day : )
