Answer:
Q' (2,4)
R' (3,1)
S' (5,3)
Step-by-step explanation:
When reflected across x-axis, the x-values stay the same but y-values change signs. Because you count how many points till the reflection line then same amount you have to go to the other side. But since it is saying x-axis, the reflection line is on x=0 so you just change the sign.
Answer:
D. (6) is the distance between 6 and 0, and the distance is negative from 6 to 0
Step-by-step explanation:
(6) means the number exists in the negative state. It is -6.
Option A - As it is -6, it cannot be greater than positive 6. So, it is incorrect.
Option B - As it is -6, it cannot be less than negative 6. So, it is wrong.
Option C - As it is -6, its distance cannot be 0 to 6, and it should not be positive.
Option D - As it is -6, its distance should be negative and the distance is from 6 to 0. Therefore, it is the correct answer.

Answer:
- 39 quarters and 41 nickels
Step-by-step explanation:
Let the number of quarters be x and nickels be y.
<u>Given:</u>
- Quarter is 25 cents
- Nickel is 5 cents
- Number of coins is 80
- Total amount is $11.80 = 1180 cents
<u>We have equations:</u>
- x + y = 80
- 25x + 5y = 1180
<u>Solve the system by elimination, subtract 5 times the first equation from the second one:</u>
- 25x + 5y - 5x - 5y = 1180 - 80*5
- 20x = 780
- x = 780/20
- x = 39
<u>Find the value of y:</u>
- 39 + y = 80
- y = 80 - 39y = 41
<u>Verify:</u>
- 25*39 + 5*41 = 975 + 205 = 1180
