X/y = 4 , x = 4y
x^2 -12y^2 = (4y)^2 - 12y^2 = 16y^2 -12y^2 = 4y^2
Answer:
75.36 feet
Step-by-step explanation:
The formula for circumference is C=2xpixr. Diameter is two times the radius so the radius is 12 feet. If we plug everything in, then 2 times pi equals 6.28 times 12 equals 75.36 feet.

Answer:
y+3/8x=-17/8
Step-by-step explanation:
y=mx+b
y=-3/8x+b
-4=-3/8(5)+b
-4=-15/8+b
-32/8+15/8=b
-17/8=b
y=-3/8x-17/8
change to standard form where x and y are on one side of the equation
y+3/8x=-17/8
Answer:
