Answer:
A=-2
B=-8
Step-by-step explanation:
In order for the system of linear equations to have infinitely many solution, they must be the same equation.
Ax-y=8
2x+y=B
We need to choose A and B so they are the same equation.
I notice they are both in the same form but in the second column you have opposites;
the -y and y.
So im going to multiply either equation by -1 so that part is exactly the same.
Don't choose both; choose only one.
Let's multiply the first equation by -1.
Doing this gives us the following:
-Ax+y=-8
2x+y=B
So now we can choose A and B so these equations appear exactly the same.
We need -A=2 and B=-8.
-A=2 implies A=(opposite of 2) which is -2.
Conclusion:
A=-2
B=-8

Answer: 34 miles
Step-by-step explanation:
Answer:
∛3, ∛3 to the fourth power, 3³∕ ², 3³∕ ², radical 3 to the fifth power
Step-by-step explanation:
I'm going to convert all these to decimal form to make it easier.
3³∕ ² = 4.5
∛3 = 1.44
radical 3 to the fifth power= 15.60
∛3 to the fourth power= 4.33
