Help anyone:( I need it now giving brainliest.

C) Your new salary is the same as your original salary

Explanation:

A 25% increase means that we multiply by 1.25

Think of 1.25 as 100% + 25% = 1 + 0.25 = 1.25

So the initial $40,000 salary bumps up to (40,000)*1.25 = 50,000 dollars per year.

Then we reduce this by 20%, so we'll involve the multiplier 0.80

Why this value? Because if you lose 20% of something, then you still keep the remaining 80%. Think of it as 80% + 20% = 100%, or you can say 100% - 20% = 80%

So the salary of 50,000 will drop to (50,000)*0.80 = 40,000

The salary is back to its original value. The new salary is the same as the old one.

Extra info (optional section)

It's not a coincidence that we end up with the same number. Why is this?

If we multiply the two decimal values (1.25 and 0.8) together, we end up with 1.25*0.80 = 1

So overall, the multiplier is 1 when we increase by 25% and then decrease by 20%. The multiplier of 1 does not change the value.

This is due to the rule 1*x = x*1 = x.

This applies to any starting value you want, and there's nothing special about the 40,000 figure.

answer: e 9, 5.75

step-by-step explanation:

step 1

find the variation ab in the x coordinate

delta x=(x2-x1)=10-> 8 units

find the variation ab  in the y coordinate 

delta y=(y2-y1)=6-> 2 units

step 2

find the coordinates point c

  x coordinate 

cx=ax+delta x*2/> cx=2+8*(2/> cx=3

  y coordinate 

cy=ay+delta y*2/> cy=4+2*(2/> cy=4.25

the coordinates of point c are (3,4.25)

step 3

find the coordinates point d

  x  coordinate 

dx=ax+delta x*4/> dx=2+8*(4/> dx=4

  y  coordinate 

dy=ay+delta y*4/> dy=4+2*(4/> dy=4.5

the coordinates of point d are (4, 4.5)

step 4

find the coordinates point e

  x  coordinate 

ex=ax+delta x*4/> ex=2+8*(6/> ex=5

  y  coordinate 

ey=ay+delta y*4/> ey=4+2*(6/> ey=4.75

the coordinates of point e are (5, 4.75)

step 5

find the coordinates point f

  x  coordinate 

fx=ax+delta x*4/> fx=2+8*(8/> fx=6

  y  coordinate 

fy=ay+delta y*4/> fy=4+2*(8/> fy=5

the coordinates of point f are (6,5)

step 6

find the coordinates point g

  x  coordinate 

gx=ax+delta x*4/> gx=2+8*(10/> gx=7

  y  coordinate 

gy=ay+delta y*4/> gy=4+2*(10/> gy=5.25

the coordinates of point g are (7,5.25)

step 7

find the coordinates point h

  x  coordinate 

hx=ax+delta x*4/> hx=2+8*(12/> hx=8

  y  coordinate 

hy=ay+delta y*4/> hy=4+2*(12/> hy=5.5

the coordinates of point h are (8,5.5)

step 8

find the coordinates point i

  x  coordinate 

ix=ax+delta x*4/> ix=2+8*(14/> ix=9

  y  coordinate 

iy=ay+delta y*4/> iy=4+2*(14/> iy=5.75

the coordinates of point i are (9,5.75)
