Help ASAP!! See screenshot below.
Anika [276]

ANSWER

The relation is not a function.

EXPLANATION

The relation is not a function because we have an x-coordinate mapping on to more than one y-coordinate.

This occurs at x=1.

The ordered pairs (1,1) and (1,3) disqualify the relation from being a function.

Hence the relation is not a function.

Masha is making a scale diagram of the front face of an aquarium. The face is shaped like a rectangle.
Marat540 [252]
Scale:
1 cm : 6 inches

---------------------------------
Length of the aquarium:
---------------------------------
5 feet = 5 x 12 = 60 inches
60 ÷ 6 = 10 
The length will be 10 cm on the scale drawing.

---------------------------------
Width of the aquarium:
---------------------------------
2 feet = 2 x 12 = 24 inches
24 ÷ 6 = 4 

The width will be 4 cm on the scale drawing.

---------------------------------
Find Perimeter:
---------------------------------
Perimeter = 2 (length + width)
Perimeter = 2( 10 + 4 )
Perimeter = 28 cm

--------------------------------------------------------------------------------------------------
Answer:  The perimeter of the scale drawing of the front face is 28 cm.--------------------------------------------------------------------------------------------------

X = amount of the 25% copper alloy
y = amount of the 60% copper alloy
amounts are in kilograms

------------------------------------------------

The first equation is 
x+y = 90
because the two alloy amounts (x and y) must combine to a total of 90 kg
We can solve for y to get
y = 90 - x

------------------------------------------------

Now onto the second equation.
x kg of the 25% alloy ---> 0.25*x kg of pure copper
y kg of the 60% alloy ---> 0.60*y kg of pure copper
In total, we have 0.25*x+0.60*y kilograms of pure copper
This is equal to 90*0.46 = 41.4 because the total amount of 90 kg alloy will have 46% copper
In short, the second equation is 0.25*x+0.60*y = 41.4

------------------------------------------------

Use the two equations (0.25*x+0.60*y = 41.4 and y = 90-x) to find x
I'm going to use substitution to plug in y = 90-x into the second equation

0.25*x+0.60*y = 41.4
0.25*x+0.60*( y ) = 41.4
0.25*x+0.60*( 90 - x ) = 41.4 <<<--- y has been replaced with 90-x
0.25*x+0.60*90 - 0.60*x = 41.4
0.25*x+54-0.60*x = 41.4
-0.35*x+54 = 41.4
-0.35*x = 41.4-54
-0.35*x = -12.6
x = -12.6/(-0.35)
x = 36

------------------------------------------------

If x = 36, then y is...
y = 90-x
y = 90-36
y = 54

------------------------------------------------
------------------------------------------------

In summary, we have
x = 36
y = 54
which means there are 36 kg of the 25% alloy
and 54 kg of the 60% alloy
