If an ordered pair is reflected on x-axis, it will result in opposite number of y. If the original y positive, the reflected point of y will be negative.

we can write it as
(x,y) -> reflected to x axis -> (x, -y)

Solution:
(x,-y) = (4.75, -2.25)
(x,y) = (4.75, 2.25)

The original point was (4.75, 2.25)

Miguel bought 8 equally priced pens for $3.84.<br><br> How much will 15 of these pens cost?
Snezhnost [94]

Answer:

$7.20

Step-by-step explanation:

If 8 pens cost $3.84, we need to find out how much ojne pen costs.

To find out the cost of one pen we need to divide $3.84 by 8.

$3.84 / 8 = $0.48

1 pen cost $0.48

We then need to work out the cost of 15 pens. So from using the information that one pen costs $0.48 we can multiply that by 15 to find out the answer.

$0.48 x 15 = $7.20

15 pens cost $7.20

How do you know if a square root of something is rational or irrational? like i know it can be represented by a fraction or a ra
ra1l [238]
The square root of a whole number will be rational if the whole number is a perfect square (i.e 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144 etc) and irrational otherwise.

Rational number is a number that can be described as m/n 

so a fraction can be a rational number, 0.8=4/5 
Irrational numbers can't be written as a fraction 

The part about the number having to be a perfect square is still correct, if it's not a prefect square than it will just keep going(a decimal that never ends) 

for example the square root of 0.64 is 0.8 
and the square root of 10 is 3.162277... 
as you can see the 0.64 one ends and is rational, whereas the 10 one just keeps going and is irrational.
