Answer 1

Answer:

Step-by-step explanation:

A- Y is a decrease.

1/4 x 100 = 100/4 =25%

25% and decrease.

B- Y is a increase

1/4 x 100 = 100/4=25%

25% and increase.

Answer 2

Answer:

In A: y is a 25% decrease of x

In B: y is a 25% increase of x

Step-by-sep explanation:

For A:

The diagram in A shows that x = 4, while y = 3.

Thus, this means that y decreased by 1, relative to x.

The percentage decease would be:

$\frac{1}{4} \times 100$

$\frac{100}{4} = 25$

Therefore, y is a 25% decrease of x.

For B:

The diagram for B shows that x = 4, while y = 5.

Thus, this means that y increased by 1, relative to x.

The percentage increase would be:

$\frac{1}{4} \times 100$

$\frac{100}{4} = 25$

Therefore, y is a 25% increase of x.
