The range is 13 because 115-102 is 13
Answer:
40 students
Step-by-step explanation:
So, first we can subtract the $25 fee from the total
1325-25=1300
Then subtract the amount for the 10 adult tickets. Each ticket is $30 and 10 adults and since 30 times 10 is 300 it cost $300 for the 10 adult tickets. Subtract that from 1300 and we get $1000 left for the student tickets. Each student ticket is $25 so we can divide 1000 by 25 to get the number of students going to the park
1000/25=40 meaning 40 students are going to the park
I hope this helps and please don't hesitate to ask if there is anything still unclear!
Answer:
R'(- 2, 4 )
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
R(4, - 2 ) → R'(- 2, 4 )
Answer:
None.
Step-by-step explanation:
The only possible restriction in the rational expression can originate in its denominator being zero for some values of a. However, since the denominator in this case (a^2+4) is always positive (and larger or equal to 4) for all values, no restrictions on the variable a exist.
