Answer:
-5
Step-by-step explanation:
3u+4=6u+19
-3u -3u
4=3u+19
-19 -19
-15=3u
÷3 ÷3
-5=u or u=-5
Circle equation
(x - h)^2 + (y - k)^2 = r^2
Since radius isn't given use the center and point, with the distance formula, to find the radius.
D=sqrt((x2-x2)^2+)y2-y1)^2)
D=sqrt((1-0)^2+(2-6)^2
D=sqrt(1+16)
D=sqrt 17
radius = sqrt 17
(h, k) is the center and r is the radius
(x - 1)^2 + (y - 2)^2 = 17
can you post a pic so i can understand it better
Answer:
Obtuse, isosceles
Step-by-step explanation:
Classify. Two same length sides make it isosceles
A larger angle than 90° make it obtuse

Answer:
Part 67)
and ![x < 3](https://tex.z-dn.net/?f=x%20%3C%203)
Part 68)
or ![x\geq 1](https://tex.z-dn.net/?f=x%5Cgeq%201)
Step-by-step explanation:
Part 67) we know that
The solution of the number line is the interval -------> (-2,3)
All real numbers greater than -2 and less than 3
so
The compound inequality could be
and ![x < 3](https://tex.z-dn.net/?f=x%20%3C%203)
"And” indicates that, both statements must be true at the same time
Part 68) we know that
The solution of the number line is the interval (-∞,-1] ∪ [1,∞)
All real numbers less than or equal to -1 or all real numbers greater than or equal to 1
The compound inequality could be
or ![x\geq 1](https://tex.z-dn.net/?f=x%5Cgeq%201)
"Or” indicates that, as long as either statement is true, the entire compound sentence is true
