$70 is the profit because 12x10=120 then 120-50
Step-by-step explanation:
10x² + 11x − 6 = 0
10x² + 15x – 4x – 6 = 0
5x(2x + 3) – 2(2x + 3) = 0
(2x + 3) (5x – 2)
P + s = 200......p = 200 - s
20p + 15s = 3400
20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold
p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold
ANSWER:
y= 11/3x-7
REASONING:
Because if you do the slip equation m=y2-y1 divided by x2-x1 you get 11/3 or -11/-3 which is equal to 11/3 which is your slop and since the y intercept is already one of your points (0,-7) then your formula would be y=11/3x-7
