Answer:
x=-2, y=-3
Step-by-step explanation:
we can rearrange the questions to make it easier
y=3x+3
2y=-3x-12
if you add the two equations, you get
3y=0x-9
so y=-9/3 = -3
plug y into one of the equations
-3=3x+3
-6=3x
x=-2
and then check your work by plugging into the other equation:
2*-3=-3(-2)-12
-6=6-12
-6=-6
Answer:
V_rocket = 44 ft^3 = 138.2 ft^3
Step-by-step explanation:
Volume of cone
V_cone = (1/3)*(*(radius^2))*h
radius = 2ft
h = height of the cone = 3 ft
pi = 3.1416
V_cone = 4 ft^3
Volume cylinder
V_cylin = (*(radius^2))*h_cyl
h_cyl = height of the cylinder = 10 ft
V_cylin = 40 ft^3
Volume rocket
V_rocket = V_cone + V_cylin = 4 ft^3 + 40 ft^3
V_rocket = 44 ft^3 = 138.2 ft^3
