Step-by-step explanation:
yes it is . becoz if you kbow the 5 is to 8 means it is an irrational number
for an expression or relation to be a function, it must not have any x-coordinate values repeated, let's check this one

The answer 1 by 8x.25 = 2 and 4x.5squared making that 1
Answer:
No.
Step-by-step explanation:
Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6, we should get a true equation.
y = 3x - 6
-9 = 3 * 1 - 6
-9 = 3 - 6
-9 = -3.
So, the points (1, -9) does not satisfy the equation y = 3x - 6.
