Please help asap! the problem is in the picture

Given:

$AB=6\ BC=r,\ CD=r,\ AD=12$ .

To find:

The value of r.

Solution:

We have,

$AB=6\ BC=r,\ CD=r,\ AD=12$ .

We know that the radius is perpendicular to the tangent at the point of tangency

AD is the tangent and CD is the radius. So, CD is perpendicular to AD at point D, i.e., $m\angle D=90^\circ$ .

Using Pythagoras theorem, we get

$AC^2=AD^2+CD^2$

$(6+r)^2=12^2+r^2$

$36+12r+r^2=144+r^2$

$12r=144+r^2-36-r^2$

On further simplification, we get

$12r=108$

$r=\dfrac{108}{12}$

$r=9$

Therefore, the value of r is 9.

|x-1| if x>1 how do you simplify this

JulsSmile [24]

Use the definition of absolute value.

$|x| = \begin{cases} x & \text{if } x \ge0 \\ -x & \text{if } x < 0 \end{cases}$

The absolute value is always non-negative. So if $x$ is already non-negative, $|x|=x$ is unchanged. But if $x$ is negative, then $|x|=-x$ because multiplying $x$ by -1 makes it positive.

Now, if $x>1$ , then by the definition of absolute value,

$x > 1 \implies x - 1 > 0 \implies \boxed{|x - 1| = x - 1}$

Y-8=-x solve for y please show work I'm trying to find the y intercept

Novay_Z [31]

x- intercept (- 8, 0), y- intercept (0, 8)

Step-by-step explanation:
To find the y- intercept, let x = 0 in the
equation and solve for y
y = 0 +8 =8 (0,8 ) y -intercept
To find the x- intercept, let y = 0 in the
equation and solve for x
x + 8 = 0 ( subtract 8 from both sides )
x=- 8 (-8, 0) intercept.
