Answer:
The individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
Step-by-step explanation:
First we have to find 2 equations to express the problem
x = value of each item
y = total amount of money
3x = y
4 ( x - 2.25 ) = y
we replace the y by (3x) in the second equation and obtain the value of x
4 ( x - 2.25 ) = y
4 ( x - 2.25 ) = 3x
4x - 9 = 3x
4x - 3x = 9
x = 9
9 - 2.25 = 6.75
this means that the individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony

Answer:
U is a point in the line segment TV
TV = TU + UV
TV = 3x
UV = x + 1
TU = x
3x = (x+1) + x
3x = 2x + 1
3x - 2x = 1
x = 1
Length of TU = 1
Hope this will help..
For this case we evaluate the function when x = 0
We then have to evaluate:
y = -2sinx - 1
y = -2sin (0) - 1
y = -1
Then, the intersection with the y-axis is -1 and the amplitude is 2.
Answer:
y = -2sinx - 1
option 2
