Y = 3x-5
(3, ) - your x is 3 in that case, y = 3*3-5 = 4 - answer (3,4)
(4, ) - your x is 4, y = 4*3-5 = 7 - answer (4,7)
( ,10) - your y is 10:
10 = 3x - 5
3x = 15
x = 5 - answer (5, 10)
Solution pairs - (3, 4); (4, 7); (5, 10)
Perimeter = 300
Area = a(w)
Width = w
Perimeter = 300 and width = w ⇒ length = [300 - 2w ]/2 = 150 - w
Area, A = width * length = w(150-w) = 150w -w^2
Roots = w = 0 and w =150
Vertex
w =[0 + 150]/2 = 75
A = 75(150-75) = 75^2 = 5625
(75,5625)
Given that the coefficient of w^2 is negative, the vertex is the maximum of the function or area.
The second coordinate of the vertex (5625) is the maximum area the fence can enclose.
Answer: the maximum area that can be enclosed by the fencing.
Hope this helps!
6.75 because .25 is a quarter of 1 and .25 times 3 is .75
You first round 289 and get 290 then multiply it by 7
48 (total chocolates)=8f (workers)
to get (f) by itself you have to divide by 8 on both sides
48/8 =8f/8
f=6
