Answer:t The volume of the box as a function of x is given by
Step-by-step explanation:
Since we have given that
Length of metal = 28 inch
Width of metal = 28 inch
Since squares are cut out of the four corners so that the sides can then be folded up to make a box.
Let the length of the sides of the squares that are cut out be 'x'.
So, Length of box would be
Width of the box would be
Height of the box would be x.
As we know the formula for "Volume of box":
Hence, the volume of the box as a function of x is given by
Step-by-step explanation:
The union of two sets contains all the elements contained in either set,
The intersection of two sets contains only the elements that are in both sets.
Top equation, minus 10 both sides to get
3x-2y=-10
bottom equation, minus 4x both sides
5y-4x=8
-4x+5y=8
now elimiate y's
multiply top equation by 5 and bottom equaiton by 2 and add them together
15x-10y=-50
<u>-8x+10y=16 +</u>
7x+0y=-34
7x=-34
divide both sides by 7
x=-34/7
sub back
3x-2y=-10
3(-34/7)-2y=-10
(-102/7)-2y=-10
add (102/7) to both sides
-2y=-10+(102/7)
-2y=(-70/7)+(102/7)
-2y=32/7
divide both sides by -2, or times both sides by -1/2
y=-32/14
y=-16/7
(x,y)
(-34/7,-16/7)
It is either 17 or 151 i believe
You should choose 25% of $950 as that gives the higher amount of money.
15% of $1,500 = $225
25% of $950 = $237.5
