Answer:
(a)y=-10x
(b)x=0.9
Step-by-step explanation:
If y varies directly with x, we write:
Therefore, a direct variation equation relating y to x is:
(a)y=-10x
(b)When y=-9
Substituting y=-9 into the equation obtained in (a) above
Hi!
To answer this, simply add all of the values together to get the final answer.
12.99 + 20.99 + 66.49 + 12.06 = 112.53

The last answer, (40 pieces of paper)
Answer:
201.06 square feet.
Step-by-step explanation:
=> The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.
=> The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.
=> Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet
Answer:
ans: centre of circle is ( -4 , 6 )
and radius is 3 unit
