Answer:
0
Step-by-step explanation:
Subtracting 3 from both sides yields 5v = -3v, or 8v = 0. Then v must be 0.
Answer:
(4,12)
(-1,-3)
Step-by-step explanation:
x^2 - y = 4
y = 3x
Use substitution. Substitute 3x for y in the first equation
x^2 - (3x) = 4
x^2 -3x =4
Subtract 4 from each side
x^2 -3x -4 = 4-4
x^2 -3x-4 =0
Factor
(x-4) (x+1) =0
Using the zero product property
x-4 =0 x+1 =0
x=4 x=-1
Now to find y for each x solution
x=4
y =3x = 3(4) =12
(4,12)
x=-1
y =3x = 3(-1) =-3
(-1,-3)

Answer:
v=50
Step-by-step explanation:
use the formula V=A(h/3), where V is the volume and A is the area of the base. a=5 h=6 5×6=30 5×3=15 30+15=45 45 rounded to neared whole number which is 50
