If Y is an external point and XY and YZ are tangent to the circle, then by definition, XY = YZ.

Then, we just plug in the values to get:

2x + 8 = 8x - 16

Combine like terms to get:

6x = 24.

Divide 6 from both sides, and you get: x = 4 units.

You use a garden hose to fill a wading pool. If the water level rises 11 centimeters every 6 minutes and you record the data poi
irina1246 [14]

Answer:

y=22\ cm

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the number of minutes

y ----> the water level in centimeters

In this problem we have a proportional relationship between the variables x and y

Find the value of k

For x=6 min, y=11 cm

k=11/6 -----> the slope is equal to the constant of proportionality k

The linear equation is

y=(11/6)x

so

For (12,y)

we have

x=12 min

substitute in the equation and solve for y

y=(11/6)12

y=22\ cm
