Answer:
(2, 4 )
Step-by-step explanation:
Given the 2 equations
y = 2x → (1)
x = - y + 6 → (2)
Substitute x = - y + 6 into (1)
y = 2(- y + 6) ← distribute
y = - 2y + 12 ( add 2y to both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Substitute y = 4 into (2) for corresponding value of x
x = - 4 + 6 = 2
solution is (2, 4 )

Answer:
1332 m³
Step-by-step explanation:
The volume of a prism is the product of its length (12 m) and the area of its base. This base is a ∩ - shape whose overall dimensions are 11 m high and 15 m wide. The "tunnel" is shown as 6 m high, but we need to calculate how wide it is.
The two "legs" are each 3 m wide, so total 6 m in width. Then the width of the "tunnel" is the difference between that and the overall width of 15 m:
tunnel width = 15 m -6 m = 9 m
__
One way to compute the base area is to subtract the tunnel area from the overall area:
base area = B = (15 m)(11 m) -(9 m)(6 m) = 165 m² -54 m² = 111 m²
The volume of the prism is ...
V = Bl = (111 m²)(12 m) = 1332 m³
The volume of the prism is 1332 m³.
