x(x-4)
Step-by-step explanation:
Answer:
It is C
Step-by-step explanation:
To get the new coordinates you would move the shape up the y-axis 8 times, and right on the x-axis 8 times as well.
You use the FOIL method for this problem. you should get X^2-25
20% of 40 is 8 :) hope that helps
Answer:
2x + 3y > 6 (1)
3x – 2y = 9 (2)
x + 5y = 20 (3)
From (1) and (2), we have:
(2x + 3y) - (3x - 2y) > 6 - 9
5y - x > -3 (4)
From (3) and (4), we have:
(x + 5y) - (5y - x) > 20 - (-3)
2x > 23
x > 12,5 (5)
From (3) and (5), we have:
x + 5y = 20 ⇔ 12,5 + 5y > 20
5y > 7,5
y > 1,5
So: C = 4x + 3y > 12,5 × 4 + 1,5 × 3 = 50 + 4,5 = 54,5
Conclusion: C > 54,5
