What would x be?????
yarga [219]

Answer:

  12 cm

Step-by-step explanation:

The square of the length of the tangent segment is equal to the product of near and far distances to the circle from the point of intersection of the secant and tangent:

  (8 cm)^2 = (4 cm)(4 cm +x)

  16 cm = 4 cm +x . . . . . . divide by 4 cm

  12 cm = x . . . . . . . . . . . . subtract 4 cm

What is the answer to –(d+1)>3
aleksandrvk [35]

Answer:

−(d+1)>3

Step 1: Simplify both sides of the inequality.

−d−1>3

Step 2: Add 1 to both sides.

−d−1+1>3+1

−d>4

Step 3: Divide both sides by -1.

\frac{-d}{-1} >  \frac{4}{-1}

d < -4

Find the slope and the y-intercept in this equation: 3y+6=-2x
Dmitry [639]
Hello,

To solve this problem, you should first put in it slope intercept form.

Here are the steps:

3y + 6 = -2x   Add 6 to both sides
3y = -2x - 6    Divide both sides by 3
y = (-2/3)x - 2

The you can see that the slope is (-2/3) and the y-intercept is (0, -2).

I hope this helps,

Solve the equation and show all work. 4|x + 1/3| = 20 <br> i'm kind of stuck hhh

Absolute value is a function that takes some number and outputs the size of that number, regardless of the sign. By definition, |x|=x if x\ge0, and |x|=-x if x.

For example,

  • |2| = 2 because the input 2 is positive, so the input is unchanged;
  • |-3| = -(-3) = 3 because the input -3 is negative, so the sign is switched.

What this means for this problem is that there are two cases to consider:

  • If x+\frac13\ge0, then \left|x+\frac13\right|=x+\frac13, so that

4\left(x+\dfrac13\right)=20\implies x+\dfrac13=5\implies\boxed{x=\dfrac{14}3}

  • On the other hand, if x+\frac13, then \left|x+\frac13\right|=-\left(x+\frac13\right), so

-4\left(x+\dfrac13\right)=20\implies x+\dfrac13=-5\implies\boxed{x=-\dfrac{16}3}
