For this case we have to:

x: Variable that represents Tyler's age

y: Variable that represents Tiffany's age

According to the data of the statement we can propose the following equations:

x = y + 4\\x + 10 = 2y

To solve we substitute the first equation in the second equation:

y + 4 + 10 = 2y\\14 = 2y-y\\14 = y

So, Tiffany is 14 years old.

Then Tyler has:

x = 14 + 4\\x = 18

Tyler is 18 years old.

Answer:

Tyler: 18 years old

Tiffany: 14 years old

Answer:

See answers below

Step-by-step explanation:

From the given functions, the equivalent function for when x = 0 is -(x-1)²

h(x) = -(x-1)²

h(0) = -(0-1)²

h(0)= -(-1)²

h(0) = -1

when x = 2, the equivalent function is -1/2x - 1

h(x) =  -1/2x - 1

h(2) =  -1/2(2) - 1

h(2) = -1-1

h(2) = -2

when x = 5, the equivalent function is -1/2x - 1

h(x) =  -1/2x - 1

h(5) =  -1/2(5) - 1

h(5) = -5/2-1

h(5) = -7/2
