Answer:
(a) (-12/13, 5/13)
(b) (12/13, -5/13)
(c) (-12/13, -5/13)
(d) (12/13, 5/13)
Step-by-step explanation:
(a) The terminal point is effectively reflected across the y-axis, so the sign of the x-coordinate changes. (-12/13, 5/13)
__
(b) The terminal point is effectively reflected across the x-axis, so the sign of the y-coordinate changes. (12/13, -5/13)
__
(c) The terminal point is effectively reflected across the origin, so the signs of both coordinates change. (-12/13, -5/13)
__
(d) The terminal point is mapped to itself, so its coordinates remain unchanged. (12/13, 5/13)
The answer should be 3x^2 -13x+7.
Answer:
C
Step-by-step explanation:
y = 2.5 x - 57
y = Profit: 143
143 = 2.5 x - 57 Add 57 to both sides
143 + 57 = 2x - 57 + 57 Combine like terms
200 = 2.5 x Divide by 2.5
200/2.5 = 2.5x/2.5
x = 80 plants
The correct answer to your equation is 25%.
