Answer:
y = 2x + 5+2 graph would shift by 2 unit.
Step-by-step explanation:
Given : y = 2x + 5 .
To find :If you wanted to shift the graph up what would be equation .
Solution : We have given that y = 2x + 5 .
BY the transformation rule ; if f(x) +k then graph would shift up by k units .
Then to shift the graph of y = 2x + 5 up we need to add something in 5
Like y = 2x + 5+2
Then graph would shift by 2 unit.
Therefore, y = 2x + 5+2 graph would shift by 2 unit.
Answer:
Adult ticket: $7 Student ticket: $11
Step-by-step explanation:
First, we set up our equations.
x (adult ticket) y(student ticket)
For the first day, 11x + 3y = 110
For the second day, 3x + 6y = 87
Then we solve.
(-2)11x + 3y =110
Equals
-22x - 6y = -220
Add them
-22x - 6y = -220
3x + 6y = 87
This equals
-19x = -133
x = 7
Plug in to find y
3(7) + 6y = 87
21 + 6y = 87
6y = 66
y= 11
Answer:
the circumference is 25.133 and the area is 50.265
