Answer:
3/5 3:5 3 to 5
1/4 1 to 4 1:4
Step-by-step explanation:
Answer:
168 = L + 2W
And you want to maximize LW.
Which means you want to maximize W (168 - 2W), or 168W - 2W^2.
To maximize that, the derivative must go to zero.
0 = 168 - 4W, or W = 42. And L = 84. Done. :-)
Step-by-step explanation:
X - 6 1/3 < = 1 1/2 ....turn to improper fractions
x - 19/3 < = 3/2 ....add 19/3 to both sides
x < = 3/2 + 19/3 ...common denominator is 6
x < = 9/6 + 38/6
x < = 47/6 = 7 5/6....first answer choice
slope = (y2-y1)/(x2-x1) (x1,y1) = (2,-5) (x2,y2) = (7,1)
= (1- (-5))/(7-2)
= (1+6)/(5
7/5
m=7/5
