Tyler is 4 years older than tiffany in ten years he will be twicse as old a tifinay.
rusak2 [61]

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

iDentify the equation of the circle that has its center at (-27, 120) and passes through the origin A. (x−27)2+(y+120)2=123 B. (
melomori [17]
The equation of a circle is given in the form (x-a)^2+(y-b)^2=r^2, where

(a, b) is the centre of the circle
r = radius

We have the centre of the circle (-27, 120)
We can work out the radius by modelling the radius as the hypotenuse of a triangle as shown in the diagram below

r^2=27^2+120^2
r^2 = 15129

The equation of the circle is

[x-(-27)]^2+[y-120]^2=15129
[x+27]^2+[y-120]^2=15129

Correct answer: option number 4
