How do you find the sum of x and y?
So to sum up the numbers between X and Y, excluding X and Y, we would sum up the numbers upto y-1, then subtract the sum of the numbers upto X, thus: S = S1-S2 = (Y-1)Y/2 – X(X+1)/2.
How do you graph a less than or equal to inequality?
When graphing a linear inequality on a number line, use an open circle for “less than” or “greater than”, and a closed circle for “less than or equal to” or “greater than or equal to”. The solution set for this problem will be all values that satisfy both -3 < x and x < 4.
What is the sum of 4 and 5 answer?
9
The sum of two numbers is the answer you get when you add them both together. So the sum of 5 and 4 is 9.
How do you write the sum of a number and 4?
1 Answer
- The ” sum of a number and 4 ” means ADD them: → x+4.
- Triple that means multiply by 3.
- → 3(x+4)
- “The sum of triple a number and 4 ” which would be.
- 3x+4.
What does F X greater than 0 mean?
If f(x)>0 f ( x ) > 0 , then the point (x,f(x)) ( x , f ( x ) ) lies above the x -axis.
What is the sum of 4 and its additive inverse?
Answer: Zero. Step-by-step explanation: Additive inverse of -4 is +4…
What is the answer of (+ 4 +5 answer?
4+5 = 9. This is your answer my friend.
What is the sum of X and Y?
The sum of two numbers, x and y, is 12. x + y = 12. lets assume x > y. The difference of four times the larger number and two times the smaller number is 18. 4x – 2y = 18 divide both sides by (4/2)x – (2/2)y = 18/2. 2x – y = 9. to find x and y we should solve the following system of equations. x + y = 12. 2x – y = 9
What is the graph of the sum of f (x) and g (x)?
The graph of f(x) [red] and g(x) [green] are\rshown: The sum of f(x) and g(x): f(x) + g(x) = (2x+3)\r+ (x+1) = 3x+4. This is still in the form of equation for a\rline. So I would expect the graph to be linear. The graph of the sum of f(x) and g(x) [red]\ris shown:
How do you graph x x and Y Y values?
Create a table of the x x and y y values. Graph the line using the slope and the y-intercept, or the points.
How do you find the sum of f (y) and g (y)?
Then the sum of f(y) and g(y)\rwould be: f(y)+g(y)=1+3=4. The graphs f(y) [red], g(y) [green], and f(y)+g(y)\r[blue] are shown:
