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
A solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.

ANSWER
EXPLANATION
It was given that,a bottle of la belle bœuf contains 3/8 ounces of perfume.
We want to find how many ounces of perfume would 4 1/2 bottles contain.
If 1 bottle contains 3/8 ounces;
Then 4½ bottles should contain more ounces.
If more less divides.
4½ bottles contain
=1.6875 ounces.
Answer:
256
Step-by-step explanation:
All of these are multiples of 4.
4^2= 16
4^3=64
4^4=256
8x^2 = 96x
8x^2 - 96x = 0
8x(x - 12) = 0
8x = 0....x = 0
x - 12 = 0
x = 12
ur number is 12
