Answer:
32/ 3 pi ft^3
Step-by-step explanation:
The volume of a sphere is 4/3 pi r^3
V = 4/3 pi r^3
The radius is 2
V =4/3 ( pi) (2)^3
V = 4/3 pi (8)
= 32/ 3 pi ft^3
Since you can factor 5 out of both 45c and 10d, the expression will be 5(9c+2d)
5(9c+2d)
=)=)=)
Answer:
its 3/5 so you just add the numerator to the numerator and add the denominator to the denominator.
It's slope would be undefined.
2x-3y=13 equation (1)
x+2y=-4 equation (2)
multiply equation (2) by -2
-2x-4y=8 now we got equation (3)
Add equations(1) and (3) and combine like terms
2x-2x-3y-4y=13+8
-7y=21
y=-21/7= -3
substitute y with -3 in equation (2) and solve
<span>x+2(-3)=-4
</span>x-6=-4
x= -4+6
x=2
the solution for the system of equations is x=2, y= -3
