Answer:
y = 46
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 23 when x = 8 , then
23 =
( multiply both sides by 8 )
184 = k
y =
← equation of variation
When x = 4 , then
y =
= 46
Answer:
37.7 inches
Step-by-step explanation:
She wants to paint the line along the circumference of the plate.
The plate is circular; the circumference of a circle is given as:
C = πD
where D = diameter
The diameter of the plate is 12 inches, therefore:
C = π * 12 = 37.7 inches
The line will be 37.7 inches long.
I think the answer is 3, because D(12;-4) and D' is (36;-12). Then 36/12=3, -12/-4=3
