Alright then! First question! A graph has height (inches) on the x-axis and arm span (inches) on the y-axis. Points are at (30, 27), (45, 45), (53, 50), (60, 60), (67, 70), and (73, 72).

Identify if there is a relationship between the variables.
(A) No, there is no relationship because the points are all up and down.
(B) Yes, the relationship displayed shows arm span increasing as height increases.
(C) Yes, the relationship displayed shows arm span decreasing as height increases.

hmmm...i wanna go with B

Step-by-step explanation:

because it goes from 30 to 45 and 45 and 45 to 53 to 50 then the 50 goes 60 meaning their both increasing as it it goes on

at least i believe im right haha hope this helped if its not to  late

Remember that you can do anything to an equation as long as you do it to both sides

also
x times 1/x=1 becasue x/x=1

try to get rid of fractions

notice we have
somethng/10 =something/20
if we times both sides by 20 we clear the 20 fraction, and double the left fraction

(2x-4)/10=(2x)/20
times both sides by 20



2(2x-4)=2x
distribute
4x-8=2x
minus 2x both sides
2x-8=0
add 8
2x=8
divide 2
x=4
distribute
