The price for senior citizens was 4 dollars and the price for the child tickets would be 7 dollars.
Answer:
Option (A)
Step-by-step explanation:
The given absolute function is,
f(x) = |-4x + 36|
If the given function f(x) ≥ 0,
(-4x + 36) ≥ 0
4x ≤ 36
x ≤ 9
If the given function f(x) < 0,
(-4x + 36) < 0
4x > 36
x > 9
Therefore, piecewise function that defines the absolute function will be,
f(x) = 4x - 36 if x ≤ 9
-4x + 36 if x > 9
Option (A) will be the correct option.
Answer:
18
Step-by-step explanation:
Answer:
$(159+x)
Step-by-step explanation:
Given
Discount price = $x
Amount Emma paid after discount = $159
Original price = Amount paid + Discount
Original price= $159 + $x
Hence the required expression is $(159+x)
Ruby's hours will represent x+6
Svetlana's hours will represent 4(x+6)
Issac will represent x.
The equation would read:
x+(x+6)+(4(x+6))=126
x+x+6+4x+24=126
6x+30=126
Subtract 30 from both sides.
6x=96
Divide 6 on both sides to get x by itself.
x=16
So:
Issac worked 16 hours
Ruby worked 22 hours
Svetlana worked 88 hours.
To check your answer, plug in the values:
16+22+88=126
126=126
Hope this helps.
