These statistics compare the population density of these countries.
Answer:
A. 9y-8x=23
B. 9y-8x=-23
C. 8y-9x=-23
D. 7y-8x=25
Step-by-step explanation:
Formula: y-mx=b
y=mx+b ------> y-mx=b
Put opposite signs
Ex: y=7x+2 ------> 7x-y=2
1.x+4y- - 67 =-1
x+4y+67=-1
x+4y=-1-67
X+4y=-68
2.2x-y+2z=-7
2x=-7+y-2z
x=-7/2+1/2y-z
x=-7/2+1/2y-z, y€R, z€R
Warning: I don’t have the € and R
3.-x+2y- -43=5
-x+2y+43=5
-x+2y=5-43
-x+2y=-38
x-2y=38
Hope this helps!
