Check the picture below.
notice, that one go-around is 2π, or namely 4π/2, and if we go 3π/2 more over, we'd end up at at 4π/2 + 3π/2 or 7π/2.
a couple of coterminal angles will be those in blue, one angle in the first go-around, and another one by simply going around one more time by 4π/2 extra, 7π/2 + 4π/2 is just that one there.
Answer:
y = x/4 + 5
Step-by-step explanation:
Solve for y:
20 - 4 y = -x
Hint: | Isolate terms with y to the left-hand side.
Subtract 20 from both sides:
-4 y = -x - 20
Hint: | Solve for y.
Divide both sides by -4:
Answer: y = x/4 + 5
P=98 m
l +9=4w
p=2l+2w
98=2(4w-9) +2w
98 = 8w-18+2w
116=10w
w=11,6 m
l = 4w-9 = 4*11,6 -9 = 46,4 -9 = 37,4 m
w=11,6 m
l= 37,4 m
Answer:
B
Step-by-step explanation:
i know
20 times 5 is 100. We can multiply 2*5 and get 10, then add another zero to make it easier.
