Answer:
The scale factor is 0.25
Step-by-step explanation:
we know that
The dilation is a non-rigid transformation that produce similar figures
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
In this problem
ABCD and A'B'C'D' are similar
therefore
Find the scale factor
Looking at the graph
we have
Let
z ---> the scale factor
substitute the values
Answer:
x = 4
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 = 8 when x = 10
k = yx = 8 × 10 = 80
y = ← equation of variation
When y = 4, then
4 = ( multiply both sides by x )
4x = 80 ( divide both sides by 4 )
x = 20
