Answer:
y = - 
x - 7
Step-by-step explanation:
Parallel lines have equal slopes.
Calculate the slope m of the given line using the slope formula
m = 
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line
m = 
= - , thus
y = - x + c ← is the partial equation
To find c substitute P(- 3, - 3) into the partial equation
- 3 = 4 + c ⇒ c = - 3 - 4 = - 7
y = - x - 7 ← equation of parallel line
-2(7-y)+4=-4
Distributive property for -2(7-y)
-14+2y+4=-4
Addition property
-14+14+2y+4=-4+14
2y+4=10
Subtraction property
2y+4-4=10-4
2y=6
Division property
2y/2=6/2
Y=3
ANSWER
EXPLANATION
The room represents a rectangular prism or a cuboid.
The dimensions of the room are 30 feet by 16 feet by 8 feet(height).
The volume of a rectangular prism is
Substitute the given values
Simplify:
Hence the cubic feet of air in the room is 3,840ft³.
Answer: 12
To get 12 you multiply 20%×60 and get 12.
Note: When finding the answer to these types of problems, multiply the percent times the number.
Answer:
volume 1050 
surface area 859 
Step-by-step explanation:
volume is length times width times height (7*25*12)/2
surface area is area of all the sides added together
2(25*12)+(12*7)+ 2(
)
