Prime numbers are numbers that are only divisible by the number themselves and 1. For example: 2, 3, and 5.
2,3,5
7,11,13
17, 19, 23
The answer is sometimes.
If the graph is linear, it would be a line, for example:
y = 2x - 5
If the graph is quadratic, it would be a curve, for example:
y = x^2 - 5x + 6
Answer:
A rational times an irrational is irrational.
Step-by-step explanation:
Let x be an irrational number and
be a rational number
We want to show that is irrational through contradiction:
Assume is rational. Rearranging, we get ;
which is a contradiction.
Therefore, a rational times an irrational is irrational.
Answer:
x=10, y=-1
Step-by-step explanation:
The coefficients of y are opposites, so the y-variable can be eliminated by adding the two equations.
... (x -y) +(2x +y) = (11) +(19)
... 3x = 30 . . . . . simplify
... x = 10 . . . . . . .divide by the coefficient of x
Use either equation to find y. We can use the first one, for example:
... 10 -y = 11
... -1 = y . . . . . add y-11
The solution is (x, y) = (10, -1).
