Answer:
March he sells 51. April he sells 107
Step-by-step explanation:
In jan he made 14 so we double that for feb and have 28.
From that 28 he takes home 5 so we are left with 23.
Then we double 28 for March to get 56 but he takes 5 home which leaves 51 to be sold and so on.

Answer:
(x+4)² + (y+9)² = 100
Step-by-step explanation:
We want to find the equation of a circle with a radius of length 10 and a center at (-4, -9).
general equation of circle : (x-h)² + (y-k)² = r²
where (h,k) is at center and r = radius
the center is at (-4,-9) so h = -4 and k = -9 and the circle has a radius of 10 so r = 10
so we have (x-h)² + (y-k)² = r²
h = -4 , k = -9 and r = 10
(x-(-4))² + (y-(-9))² = 10²
==> apply double negative sign rule and remove parenthesis for -(-4) and -(-9)
(x+4)² + (y+9)² = 10²
==> simplify exponent
(x+4)² + (y+9)² = 100
and we are done!
Is there supposed to be a picture? (A graph)
Don't repost because somebody will answer (probably)
we got some points
normally it is like
y=mx+b
find m and x
if we assume they are in a straight line
m is slope and b is y intercept
ok so we see the slope betwee (6,11) and (3,5) is 2
because slope between (x1,y1) and (x1,y1) is (y2-y1)/(x2-x1)
y=2x+b
if we solve for b we get
hmm
5=2(3)+b
5=6+b
-1=b
y=2x-1
so double x and minus 1 to get y
10*2=20, 20-1=19
23=2x-1
24=2x
12=x
the missing points are 19 on right side and 12 on left
rule is y=2x-1 or
2x-y=1
