x + y = 4
x − y = 6
Answer:
x=5 , y= -1
Step-by-step explanation:
You can see that one of the y's is negative while the other is positive, so you can add them together.
Now, negative 1 + positive 1 = 0, so the y's cancel out leaving only the x's.
Remember you can't add one part without adding the other so x+x = 2x, and 4+6=10. This makes the final equation 2x=10.
You can simplify that into x=5. This gives you the answer for x
Then substitute x=5 into any of the two equations (doesn't matter) I'll use the first one. So if you substitute it you get 5+y=4.
Simplified, y= -1
Therefore, x= 5 and y=-1
Answer:
(5,-1)

Got it right on edge cause of the guy above me
there are 4 single digit whole numbers represented by A, B, C, D. They are all different numbers.
when you multiply ABCD with D, you get DCBA
solve for the values of A,B,C, and D
(note: if A=2,B=3,C=4,D=5 then ABCD=2,345, but that is not the solution)

Range:
Answer:
The domain is
The range is
Step-by-step explanation:
we know that
The domain of the function graphed is the interval------> (-∞,4]
-----> All real numbers less than or equal to
The range of the function graphed is the interval------> [0,∞)
-----> All real numbers greater than or equal to
The domain of the function is the interval and the range of the function is the interval .
Further explanation:
Domain
The domain of the function is the set of all input values for the function that all are independent variables.
The values from domain of the function represent on the axis of the graph.
The domain is the set of real numbers that is defined on the function.
It can be seen from the given graph that the function does not provide any output values for .
Therefore, the domain for the function is .
Thus, the domain of the function is the interval that means all the real number less than or equal to 4.
Range:
The range of the function is the set of all output value of the function.
The range of the function is the subset of the co-domain.
The elements of the range represents on the axis and these all are dependent values.
It can be seen from the given figure that the graph of the function is only shown above the axis that means the output values of the function is only positive real numbers.
Therefore, the range of the function is all real numbers greater than or equal to 0.
Thus, the range of the function is the interval .

We can see here that the LL theorem holds for proving right triangles congruent because it addresses the unique characteristics of right triangles. In a right triangle, one of the angles is a right angle, measuring 90°.
A theorem is a statement or proposition that has been proven to be true based on previously established facts, axioms, or other theorems. In mathematics, a theorem is a fundamental concept and plays a crucial role in the development and understanding of mathematical theories and principles.
The LL theorem, also known as the Leg-Leg Congruence Theorem, states that if two legs of one right triangle are congruent to the corresponding legs of another right triangle, then the two triangles are congruent.
