Answer:
Step-by-step explanation:
3n+8=35
subtract 8 on both sides
3n=27
n=9
Answer:
Not a function fails the vertical line test
Step-by-step explanation:
This is not a function. The value of x = -1 goes to two different values of y
This would fail the vertical line test
Using the equations y-3x=3 and x+y=31 you can find that x=7 and y=24. There for x is the smaller of the two numbers.
Answer:
Is a consistent independent system
Step-by-step explanation:
we know that
If a system has at least one solution, it is said to be consistent .
If a consistent system has exactly one solution, it is independent .
If a consistent system has an infinite number of solutions, it is dependent
If a system not have solution, it is said to be inconsistent
we have
----> equation A
----> equation B
----> equation C
substitute equation A and equation B in equation C

Solve for z

The solution is the point (5,6,11)
The system has only one solution
therefore
Is a consistent independent system
Yup, the amount of 0's is the exponent. for example 1000= 10^3, hope this helped :)
