Answer:
t > 7
Step-by-step explanation:
2 paperclip points = 3 mm apart
After each trial, points are 2mm more apart ;
That is
Trial 1 : 3mm
Trial 2 : 5 mm
Trial 3 : 7 mm
Trial 4 : 9 mm
Trial 5 : 11 mm
Trial 6 : 13 mm
Trial 7 : 15 mm
Trial 8 : 17 mm...
Hannah reports feeling 1 point until the point are 15m apart which is equal to 7th trial
Hence, she starred reporting feeling 2 points after the 7 th trial
t > 7
Hence, the inequality
Multiply 15 times 2 I’m not sure
Answer:
y = -1
x = -1
Step-by-step explanation:
Answer:
1). Profit = 3x - 180
2) Profit of selling 1000 video games = $2820
Step-by-step explanation:
Expression for the revenue = 5x² + 2x - 80
Expression for the production cost of the video games = 5x² - x + 100
Since, profit is the difference between the revenue and the cost,
Expression for the profit will be,
Profit = Revenue - Cost
= (5x² + 2x - 80) - (5x² - x + 100)
= 5x² + 2x - 80 - 5x² + x - 100
= 3x - 180
Here, x = Number of video games sold
If number of video games sold = 1000
Profit = (3×1000) - 180
= 3000 - 180
= $2820
