Answer: C - 15.81
Step-by-step explanation:
pythagorean theorum: a^2 + b^2 = c^2
13^2 + 9^2 = c^2
169 + 81 = c^2
c^2 = 250
root both sides
c = 15.81
Answer:
147.06 a night
Step-by-step explanation:
129x.14=18.06
18.06+129=147.06 a night
Answer:
When something is viable, it means that it would be able to live on its own how ever non-viable is totally opposite, it needs help.
Step-by-step explanation:
Answer: The graph is shown below
The solution to the system is (x,y) = (2,3)
=============================================================
Explanation:
To graph 
, we need two points. Generating any (x,y) point involves picking a random x value to find its paired y value. For instance, if you plugged in x = 0, you should get to y = -2 which is the y intercept. Then trying something like x = 2 will lead to y = 3. This line goes through (0,-2) and (2,3). This line is shown in red below.
The blue line is horizontal and goes through 3 on the y axis. Every point on this horizontal line has the same y coordinate of 3. The x value doesn't matter, so it's not part of the equation y = 3.
The intersection of the red and blue line is the solution to the system. That intersection occurs at (x,y) = (2,3). This means x = 2 and y = 3 pair up together to make both original equations true.
Since this system has at least one solution, we consider it a consistent system.
Answer:
15
Step-by-step explanation:
Opposite angles, angles that are opposite each other when two lines cross, are also known as vertical angles because the two angles share the same corner. Opposite angles are also congruent angles, meaning they are equal or have the same measurement.
Therefore 60 = x + 45 or 60 - 45 = x =15
