Which value, when placed in the box, would result in a system of equations with infinitely many solutions?
Fantom [35]

Answer:

<h2>If we placed the number 10 in the box, we obtain a system of equations with infinitely many solutions.</h2>

Step-by-step explanation:

The given system is

y=2x-5\\2y-4x=a

<em>It's important to know that a system with infinitely many solutions, it's a system that has the same equation</em>, that is, both equation represent the same line, or as some textbooks say, one line is on the other one, so they have inifinitely common solutions.

Having said that, the first thing we should do here is reorder the system

y=2x-5\\2y=4x+a

This way, you can compare better both equations. If you look closer, observe that the second equation is double, that is, it can be obtained by multiplying a factor of 2 to the first one, that is

y=2x-5\\2y=4x-10

So, by multiplying such factor, we obtaine the second equation. Observe that a must be equal to 10, that way the system would have infinitely solutions.

Therefore, the answer is 10.

Reference angle for -19pi/6? 
kow [346]
\bf \cfrac{19}{6}\implies 3+\cfrac{1}{6}&#10;\\ \quad \\\\&#10;\cfrac{-19\pi }{6}\implies -\left(3\pi +\cfrac{1\pi }{6}  \right)\impliedby clockwise&#10;\\ \quad \\\\&#10;or\implies -\left(2\pi +\pi +\cfrac{\pi }{6}  \right)

go that much "clockwise", you'll end up at the 2nd quadrant,
the reference angle, is its reflective angle on the 1st quadrant
