The mode is 7 think of mode- most- the most numbers in the data set is 7 so thats the mode.
Range, you take biggest # - smallest.
9-1 =8 so the range is 8
80 just add 22+31+18+9=80
The first step to solving this is to solve the equation for x
x = - 21/5 - y
4x + 4y = -14
now,, substitute the given value of x into the equation "4x + 4y = -14"
4( - 21/5 - y) + 4y = -14
next,, solve the equation for y
y∈∅
since this system has no solution for y, your answer is (x,y)∈∅
