Answer:
Step-by-step explanation:
6x-3y+10=0 ⇒-3y=-6y-10 ⇒ y=-6x/-3 -10/-3⇒ y=2x+10/3
2x -y +9 =0 ⇒ -y=-2x-9 ⇒y=2x+9
<h2>y=2x+10/3</h2><h2>y=2x+9</h2><h2 /><h2 />
Answer: After 5 minutes, the plane is at 20,000 feet. It descended a total of 10,000 feet.
Step-by-step explanation:
f = feet above ground
r = rate of descent
m = minutes
f = 30000 - r · m
f = 30000 - 20000m
After five minutes:
f = 30000 - 2000(5)
f = 30000 - 10000
f = 20000

Answer:
Length: 48
Width: 12
Step-by-step explanation:
Substition
l - 2w = 24
I = 60 - w
60 - w - 2w = 24
60 - 3w = 24
-3w = -36
w = 12
Substitute it into the equation to get the length.
l = 60 - 12
l = 48
