Has to be c. x=8 y=8sqrt(2)
if you ever wonder why we multiply both sides by the LCD, well is just to do away with the denominators.
now, notice something, if we multiply the first equation by say -2, we end up with
-2( -2x + 7y ) = -2( -5 )
4x - 14y = 10
well well well, low and behold the second equation is really the first equation in disguise, so both equations are really the same thing, namely is the same exact line, and so their graph is just one line pancaked on top of the other, which means every single point in the lines are solutions namely infinitely many solutions.
that said, let's proceed with the substitution
Answer:
A
Step-by-step explanation:
The normal probability has two parameters mean and standard deviation. Every normal probability distribution can become a standard normal probability distribution when mean is zero and standard deviation is 1. This means that standard normal probability distribution centers at 0 and the spread about the mean is 1.
Hello.
The mathematical symbol that would best fill the blank to compare both numbers is '>', which indicates a number is greater than the other.
Hope I helped.
