Answer:

  • See below

Step-by-step explanation:

We assume Q is between P and R.

<u>According to segment addition postulate we have:</u>

  • PQ + QR = PR

<u>Substitute values and solve for x:</u>

  • 7x - 3 + 32 -2x = 59
  • 5x + 29 = 59
  • 5x = 30
  • x = 6

<u>Find PQ:</u>

  • PQ = 7*6 - 3 = 42 - 3 = 39 units

<u>Find QR:</u>

  • QR = 32 - 2*6 = 32 - 12 = 20 units

6x/11+2= -2<br><br> what is x?<br> pls hurry I need help<br> Do NOT convert to a decimal
UNO [17]
X both sides by 11
=6x+2=-22
-2 from both sides
=6x=-24
both sides /6
=x=-3

Answer:

<em>Center: (3,3)</em>

<em>Radius: </em>2\sqrt{5}<em />

Step-by-step explanation:

<u>Midpoint and Distance Between two Points</u>

Given two points A(x1,y1) and B(x2,y2), the midpoint M(xm,ym) between A and B has the following coordinates:

\displaystyle x_m=\frac{x_1+x_2}{2}

\displaystyle y_m=\frac{y_1+y_2}{2}

The distance between both points is given by:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Point (5,7) is the center of circle A, and point (1,-1) is the center of the circle B. Given both points belong to circle C, the center of C must be the midpoint from A to B:

\displaystyle x_m=\frac{5+1}{2}=\frac{6}{2}=3

\displaystyle y_m=\frac{7-1}{2}=\frac{6}{2}=3

Center of circle C: (3,3)

The radius of C is half the distance between A and B:

d=\sqrt{(1-5)^2+(-1-7)^2}

d=\sqrt{16+64}=\sqrt{80}=\sqrt{16*5}=4\sqrt{5}

The radius of C is d/2:

r =4\sqrt{5}/2 = 2\sqrt{5}

Center: (3,3)

Radius: 2\sqrt{5}
