(5,11) (-5,-1)
Slope = (11 + 1) / (5 + 5)
= 12/10
= 6/5
Answer:
Step-by-step explanation:
x+y = 175
y = 175 - x
f(x) = (x+3)(y+4)
= x(175-x) + 3(175-x) + 4x + 12
= 175x - x² + 525 - 3x + 4x + 12
= -x² +176x + 537
f'(x) = -2x + 176
maximum when x = 88
y = 175-x = 87
Answer:
27cm^2
Explanation:
3 x 9 = 27
