The square root of (64/225) is the same as √64 / √225 .
That could make the whole thing easier.
Do you know what either of those separate square roots is ?
You're right ! I'm so impressed!
The square root of 64 IS 8, and the square root of 225 surely is 15 .
You really know your stuff !
So now, the expression is √64 / √225 = <em>8 / 15</em> .
Oh, I almost forgot, it has a negative sign before it. OK,so the answer is <em>- 8/15</em> .
Hello Again! The answer would be C. (8,11)
To confirm we will plug the numbers x = 8, Y = 11
------------------------
2x - 5 = y
(2 x 8) - 5 = 11
16 - 5 = 11
------------------------
y = x + 3
11 = 8 + 3
------------------------
So now you can determine that the answer would be (8,11)
Answer:
Step-by-step explanation:
Solve like a normal equation by isolating the variable and then dividing by the coefficient.
Answer:
Yes, it is. Functions can only have one output (y) for each input (x). Furthermore, this means each x value will only have one y passing through it. Thus if we plot it on a graph and it passes through a horizontal line more than once, it is not a function. This is called the vertical line test.
