Answer:
A; infinitely many solutions
Step-by-step explanation:
first, let's simplify the first equation to make it simpler.
divide both sides by 5
y=3x-8
new system
y=3x-8
y=3x-8
as you can see, they are the same.
not mandatory but useful!⬇⬇⬇⬇
just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.
3x-8=3x-8
add 8 to both sides; subtract 3x from one side
0=0
the answer is A, Infinitely many solutions.

Answer:
D. 267.9 in3
Step-by-step explanation:
So we know the diameter is 16 inches.
So we need to find the radius and we do that by: 16/2 = 8 then it is reduced by half: 8/2 = 4
Now we need to find the volume.
V= 4/3 times 3.14 times 4^3= 268.08
So we would need to round which would give us 267.9 in3.
Therefore the answer is the D. 267.9 in3.
I hope this helps!!!
A. Is the answer first choice
i think an estimate for the answer would be around 90 degrees
Reduces to ,7=19. no solutions
