Plug in f(6) so it would be -2/3(6)+5= 1
So ur answer would be one
We know that the area is 20.
Since 20 is a small number: lets list out possible combinations of lengths and widths.
1 * 20
2 * 10
4 * 5
L = 7 + 3w
lets see which on makes sense.
L = 7 + 3w
20 = w7 + 3w^2
3w^2 + 7w -20 = 0
(3w - 10)(w - 2)
w can equal 10/3 or 2.
So the dimensions: are Width = 2 Length = 10
Answer:
2
Step-by-step explanation:
We need to plot the points in a graph and see the general shape of the curve.
<em>Attached is the graph.</em>
<em />
This Upside Down "U" shaped curve is that of a parabola, which has the general form
Thus, we see, the function is a 2nd degree function, highest power is 2.

One pound of the item will cost 4.74 bill
Step-by-step explanation:
In this problem, we are told that Delia bought 4.5 pounds of fruit
and paid with a toa total bill of 20+5= 25 bill
and also she received a change of 3.67
this means that the item she bought cost 25-3.67= 21.33bill
now if 4.5 pounds of items cost 21.33 bill
then 1 pound will cost Xbill
cross multiply and solve for Xbill
X= 21.33/4.5
X= 4.74 bill
One pound of the item will cost 4.74 bill
Yes because you end up with 4,900 which is 70x70
