You can use substitution for this.
x+5 = 5x -11
Combine like terms
16=4x
Divide 4 on both sides to isolate the x
x=4
Plug x=4 to one of the equations
y= 4 +5
Combine like terms
y=9
So the answer is A. (4,9)
I hope this helps you out a bunch hun :)

Solution:
we are given that
The magnitudes of the moon and Sirius are -12.5 and -1.44 respectively.
we have been asked to find approximately how many times is the moon brighter than Sirius?
The word magnitude is used by the scientist to describe the brightness of moon/star/object etc.
So we can find the brightness by dividing the given values. so we get
Hence we can say
The moon is 8.68 times brighter than Sirius.
we are given
basketball player Chauncey Billups of the Detroit Pistons makes free throw shots 88% of the time
so, probability of making shot is
=88%
so, p=0.88
To find the probability of missing first shot and making the second shot
so, we can use formula
probability = p(1-p)
now, we can plug values
we get
So, the probability that he misses his first shot and makes the second is 0.1056........Answer
