Since PB' = (3/5)*PB, the scale factor is 3/5, the 2nd choice.
Option D
<u>Answer:
</u>
y =
is the equation representing proportional relationship.
<u>
Solution:
</u>
For the proportional relationship, for all values of x,
must be a constant value.
Let’s check option A.

Divide both the sides by x.

For x = 1,

For x = 2,

So
is different for x = 1 and x = 2.
So option A do not represent proportional relationship.
Similarly for option B and C also there is constant term in the equation.
So option B and C will also have different values of
for two values of x.
For option D

So for all value of x in above case y/x will be 1/3 .hence D is correct option , that is y = (1/3)x is the equation represents proportional relationship.
Your answer would be (6,8)
2 (x - 3) = 2
2x - 6 = 2
2x = 2 + 6
2x = 8
x = 8 / 2
x = 4
So, your final answer is 4
Hope this helps!
Cup A
<em><u>Formula</u></em>
V = 1/3 pi r^2 h
<em><u>Givens</u></em>
r = d/2 = 2/2 = 1 inch
pi = 3.14
h = 4 inches
<em><u>Solution</u></em>
V = 1/3 * 3.14 * 1^2 * 4
V = 4.187
Cup B
<em><u>Formula</u></em>
V = pi * r^2 * h
<em><u>Givens</u></em>
pi = 3.14
r = d/2 = 2/2 = 1
h = 6
<em><u>Solution</u></em>
V = pi * r^2 * h
V = 3.14 * 1^2 * 6
V = 18.84
<em><u>Answer</u></em>
VB - VA = 18.84 cu in - 4.187 = 14.65 = 14.7 Rounded.
