I think it’s 7x plus -4x which equals -3 then u would do 2 plus -7 which equals-5 so it will be positive 8 I think I do t really know I tried
5/3 or $1.66, $1.66, and $1.67
k = 
and b = 
Given 2 points that lie on the graph of y = kx + b then the coordinates of these points will make the equation true. Substituting the coordinates into the equation allows us to find k and b
(2, 10) → 10 = 2k + b → (1)
( - 7, - 10) → - 10 = - 7k + b → (2)
subtracting (2) from (1) term by term gives
(10 - (- 10)) = (2k - (- 7k)) + (b - b)
20 = 9k → ( divide both sides by 9)
k =
Substitute this value into ( 1) or (2) and solve for b
(1) → 10 = (2 × ) + b
hence b = 
-

They should purchase the $369 one with the $9 plan.
330 + (14x8) =442
369+ (9x8) = 441
Hope this helps!
Answer: d) Easton
<u>Step-by-step explanation:</u>
Let's evaluate Round 1 (blue) for each bowler:
Jimmy --> the lowest score is 0.5 SD below the mean
Claudia --> the lowest score was the mean
Easton --> the lowest score is 0.75 SD below the mean
Cynthia --> the lowest score was the mean
The person that had the worst game is: Easton
