-6 +8x = -38
8x = -32
x = -4
I did this by first adding 6 to both sides to get 8x by itself. I then divided by 8 to get x by itself. I remembered to use the - - + rule (Two negatives make a positive, a positive and a negative make a negative). Hope this helps!

Answer:
#5a: After 3 weeks, they will have a total score of 415 points.
#5b: (Full work below) Kris' score: 520 ; Justin's score: 450
Step-by-step explanation:
-------------------------------------------------------------------------------------------------------
#5b FULL WORK BELOW
-------------------------------------------------------------------------------------------------------
x=number of weeks: 10
y= total score
Use your equations.
Kris will have 520 points.
Justin will have 450 points.
The center is at origin O(0,0).
If it contains the point, P(-8,6), then the radius r is, by Pythagoras theorem,
r=sqrt((-8)^2+6^2)=10
The general equation of a circle at centre (xc,yc) with radius r is given by
(x-xc)^2+(y-yc)^2=r^2
Substituting r=10, (xc,yc)=(0,0)
the resulting equation is therefore
(x-0)^2+(y-0)^2=10^2
or simply
x^2+y^2=100
