Answer:
perpendicular
Step-by-step explanation:
x = -2 is a vertical line at x = -2
y is a horizontal line the two lines are perpindicular
1) Since an increase of 25% represents an increase of 1/4 of the whole.
2) And we have 4/5, increasing 1/4 we'll write:

3) So representing in the diagram an increase of 25% would be:
x =4/5
x(1.25) =y
4/5(1.25) =1
Answer:

Step-by-step explanation:

Multiplying the term by x, adds 1 to the power.
EG

Therefore

When you divide by a fraction, flip the fraction over and change divide to multiply:
3/2 / 1/8 would become:
3/2 x 8/1
8/1 simplifies to 8
You get:
3/2 x 8 = 12
The answer is:
Three-halves times 8 = 12
