Answer:
Nine
Step-by-step explanation:
3 dollars for children tickets : x
5 dollars for adult tickets: y
Equation is:
3x+5y=57
Where 57 is the total amount spent
x+y=15
where 15 is the total number of tickets bought
3x+5y=57
5(x+y)=5(15)
___________________
3x+5y=57
5x+5y=75
minus the equations top to bottom=
-2x= -18
x= -18/(-2)
x=9
He bought a total of 9 children tickets
Volume id proportional to the cube of the dimensions.
The volume of the larger room is 10 x (2 cubed)
= 80 cubic metres.
Answer:
Step-by-step explanation:
1. As x approaches zero from the right, the line representing f(x) approaches 0. As x approaches zero from the left, the line representing f(x) approaches -4 (this is the answer to the 3rd part). These two limits are different, so the limit as x approaches zero is said to be "does not exist."
2. The line representing f(x) approaches 1 as x approaches 1 from the right. The limit is 1.
3. See 1. above. The limit is -4.
