Answer:
k = 4
Step-by-step explanation:
Given that a varies directly as b then the equation relating them is
a = kb ← k is the constant of variation
To find k use the condition a = 8 when b = 2
k =
=
= 4
Answer:
the square root of 5=2.2361
Answer:
Both of these values don't have asymptotes.
Answer:
70
Step-by-step explanation:
35 because the 4 segments have to total to 180
X+y=11
x is longer than y
x>y
x is 4 less than 4 times y
x=-4+4y
sub back
x+y=11
-4+4y+y=11
-4+5y=11
add 4 to both sides
5y=15
divide both sides by 5
y=3
sub back
x=-4+4y
x=-4+4(3)
x=-4+12
x=8
the pieces are 8ft and 3ft
