Answer:
Set of all real numbers
Step-by-step explanation:
When we talk of domain, we mean the possible values of x that the equation can take without being undefined
So x-values that makes the equation defined are the domain of the graph
From the diagram, we can see that the graph extends from negative infinity to positive infinity
What this mean is that the possible values here come from the top right and extends to the left
So this means that the range of possible values are the set of all real numbers
Please don't give me credit, but I want to say that;
1. You need a picture attached to this
2. Make sure you add if 5 feet is the length or width, in addition to the 3 feet
3. The width can't be a negative value, so eliminate the negative answers
4. For the second answer, why is there a coma preceding another value? The width can can only be one value
You can add all these elements
Hoped this helped!
Let
x----------> the first number
y---------> the second number
z--------> the third number
we know that
x+y+z=19-----> z=19-x-y------> equation 1
2x+4y+5z=72-----> equation 2
4x-y=12------> equation 3
substitute equation 1 in 2
2x+4y+5*[19-x-y]=72----> 2x+4y+95-5x-5y=72----> -3x-y=-23
3x+y=23------> equation 4
add equation 3 and equation 4
4x-y=12
3x+y=23
--------------
7x+0y=35--------> x=35/7----------> x=5
4x-y=12------> y=4x-12----> y=4*5-12----> y=8
z=19-x-y------> z=19-5-8----> z=6
the answer is
the numbers are
5
8
6
64 cups
there are 16 cups in a gallon so 16 times 4
Answer:
4-12x
Step-by-step explanation:
-2/3*-6 is 4
-6*2 is -12
4-12x
