Answer:
( , -
)
Step-by-step explanation:
given the 2 equations
2x + 3y = - 4 → (1)
4x - y = 11 → (2)
Rearrange (2) expressing y in terms of x, that is
y = 4x - 11 → (3)
Substitute y = 4x - 11 into (1)
2x + 3(4x - 11) = - 4
2x + 12x - 33 = - 4
14x - 33 = - 4 ( add 33 to both sides )
14x = 29 ( divide both sides by 14 )
x =
Substitute this value into (3) for corresponding value of y
y = (4 × ) - 11 =
-
= -
= -
solution is ( , -

By definition, the volume of a cone is given by:
Where,
r: cone circular base radius
h: height of the cone
Substituting values we have:
Rewriting the equation we have:
Answer:
An expression that represents the volume of the cone, in cubic units is:
Note: rewrite the options again.
Answer:
--- The equation
