Answer:
6 less-than-or-equal-to x less-than infinity
Step-by-step exhplanation:
y = 2(x - 6)^½
x - 6 》0
Because square root of negative values is not real
x - 6》0
x》6
This is the same as:
6《x < infinity
Answer: for the box. x 5 / -2 / 2 / -1 / 0 / -3 / 3

Step-by-step explanation:
Step-by-step explanation:
Let's say the two digit number is 10x + y, where x is the first digit and y is the second digit.
The sum of the digits is 8:
x + y = 8
If 8 is subtracted from the number, the digits switch place.
10x + y − 8 = 10y + x
Simplify the second equation:
9x − 8 = 9y
Substitute from the first equation.
y = 8 − x
9x − 8 = 9 (8 − x)
9x − 8 = 72 − 9x
18x = 80
x = 4.444
There's a problem. x isn't an integer. Are you sure you copied the problem correctly? Perhaps you meant if 18 is subtracted from the number, the digits switch place.
9x − 18 = 9 (8 − x)
9x − 18 = 72 − 9x
18x = 90
x = 5
y = 8 − x
y = 3
So the number is 53.
Answer:
1 inch.
Step-by-step explanation:
The length of a side of the new square = square root of 25 = 5 ins.
So a side of the original square = 5 - 4 = 1 inch.
