930,000,000 would be your answer
Answer:
Use a matrix equation to solve the system of linear equations: -2x + 4y= 2, -3x+7y=7 *
Answer:
={6,7,8,9,10}.
Step-by-step explanation:
We have an empty set: M={} and the set N={6,7,8,9,10}.
The union of these two sets are elements in M or N or both.
Since the M is a null set, 
Therefore: ={6,7,8,9,10}.
The union for the given sets is {6,7,8,9,10}.
Answer:
66
Step-by-step explanation:
Use the combination formula.
<span>tan θ is defined as the opposite/adjacent side to the angle in a triangle
in this case you have a triangle which forms from (0,0) to (5,0) and (5,15), with </span><span>θ at (0,0)
-> your x coordinate is the adjacent side, and y the opposite
</span>
<span>tan θ=opposite/adjacent=y/x=15/5=3</span>
