Answer:
The correct answer is : Fourth, PR = 6
Step-by-step explanation:
PR is mid segment ( median line) of the side YZ in the triangle XYZ and is equal it's half.
PR = 1/2 YZ = 1/2 · 12 = 6
PR = 6
God with you!!!
So that is equal to 180 miles per 2 hours which is 90 miles per hour if each hour has the same m/hr rate.
You can set up a proportion:
let x = number of miles per hour
![\frac{x}{180} = \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B180%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20)
cross multiply and you get
2x=180
divide both sides by 2 and you get
x=90
so you get the same answer both ways,
90 miles per hour
The anwser to your question is 1 and 5/7
Answer: There's an increasing interval between -1 and 1
While x goes from -1 to 1, the value of y increases (from -2 to 2).

Answer:
14 units
Step-by-step explanation:
The angle bisector divides the sides proportionally, so you have ...
(x+4)/8 = (2x+1)/12
3(x +4) = 2(2x +1) . . . . . . multiply by 24
3x +12 = 4x +2 . . . . . . . . eliminate parentheses
10 = x . . . . . . . . . . . subtract (3x+2)
Then BD = x+4 = 10 +4.
The length of BD is 14 units.

The "triangle" cannot exist, as the side lengths are shown as 8, 12, and 35. The long side is too long. Nice math; bad geometry.
