Answer:
Y= -2x -11
Step-by-step explanation:
Y-y1=m(x-x1)
Y- -1= -2(x- -5)
Y+1= -2x -10
Y= -2x -11
4x=3(x-6)-2
distribute
4x = 3x-18 -2
combine like terms
4x =3x-20
subtract 3x from each side
x = -20
Let width = w
Let length = l
Let area = A
3w+2l=1200
2l=1200-3w
l=1200-3/2
A=w*l
A=w*(1200-3w)/2
A=600w-(3/2)*w^2
If I set A=0 to find the roots, the maximum will be at wmax=-b/2a which is exactly 1/2 way between the roots-(3/2)*w^2+600w=0
-b=-600
2a=-3
-b/2a=-600/-3
-600/-3=200
w=200
And, since 3w+2l=1200
3*200+2l=1200
2l = 600
l = 300
The dimensions of the largest enclosure willbe when width = 200 ft and length = 300 ft
check answer:
3w+2l=1200
3*200+2*300=1200
600+600=1200
1200=1200
and A=w*l
A=200*300
A=60000 ft2
To see if this is max area change w and l slightly but still make 3w+2l=1200 true, like
w=200.1
l=299.85
A=299.85*200.1
A=59999.985
Answer:
3x - 20 = 5
Step-by-step explanation:
Answer:
I would say the first one
Step-by-step explanation:
The others don't make any sense, and that is the only one that mentions 2 x and 5 1s.
