Answer:
Step-by-step explanation:
d(t)=-2t^2+9t+18
calculate the derivate : f'(t) = - 4t+9
f'(t) = 0 : - 4t+9= 0 so t = 9/4
the maximum value is f(9/4) = ....... continue
2x - y = -2 . . . (1)
5x - 2y = -7 . . . (2)
From (1), y = 2x + 2 . . . (3)
Putting (3) into (2), gives:
5x - 2(2x + 2) = -7
5x - 4x - 4 = -7
x - 4 = -7
x = -7 + 4 = -3
y = 2(-3) + 2 = -6 + 2 = -4.
Therefore, the required answer is (-3, -4)
Answer:
I believe that would be the rate..
Step-by-step explanation:
Use copy dot flip to solve.
= 3 5/7 / 2/1
= 26/7 * 1/2 (Turned into improper fraction)
= 26/14 (Improper Fraction Answer)
= 1 12/14 (Mixed Number Answer Simplified)
= 1 6/7 (Final Answer Simplified)
Hope This Helped! Good Luck!
