Answer:
(4, 5 )
Step-by-step explanation:
x + y = 9 → (1)
x - y = - 1 → (2)
adding the 2 equations term by term will eliminate y
2x + 0 = 8
2x = 8 ( divide both sides by 2 )
x = 4
substitute x = 4 into either of the 2 equations and solve for y
substituting into (1)
4 + y = 9 ( subtract 4 from both sides )
y = 5
solution is (4, 5 )

Step-by-step explanation:
2 lines intersect at (1,2)
so answer is Yes.
(1,2) is the solution to the system.
I assume we are writing the equation. The sum of a number and 14 is less than or equal to three times the number.
Let's put in a few values.
The sum of a number = x and + 14 is less than < or equal to = three times 3 * the number.
Now we have: x + 14 is < or = 3 * the number.
We can just remove the "is" and "or", because this is normal math patterns.
x + 14 <= 3 * the number.
"The Number" is referring to the "a number" at the very beginning. So we can replace that with the same variable.
x + 14 <= 3x
Answer:
No
Step-by-step explanation:
This is the general rule for any function, where a function cannot have more than one x value for every y value, there is only one output for every input.
You can also use the vertical line test which states that anything that hits the line more than once is not a function.
