Answer:
and ![x = 0.381](https://tex.z-dn.net/?f=x%20%3D%200.381)
Step-by-step explanation:
![y = \sqrt x\\](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%20x%5C%5C)
![y = x - 1](https://tex.z-dn.net/?f=y%20%3D%20x%20%20-%201)
Required
y, when they are equal.
To do this, we set them to another
![\sqrt{x} = x - 1](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%3D%20x%20-%201)
Square both sides
![x = (x - 1)^2](https://tex.z-dn.net/?f=x%20%20%3D%20%28x%20-%201%29%5E2)
Expand
![x = x^2 - 2x + 1](https://tex.z-dn.net/?f=x%20%3D%20x%5E2%20-%202x%20%2B%201)
Collect like terms
![x^2 -x-2x+1 = 0](https://tex.z-dn.net/?f=x%5E2%20-x-2x%2B1%20%3D%200)
![x^2 - 3x + 1 = 0](https://tex.z-dn.net/?f=x%5E2%20-%203x%20%2B%201%20%3D%200)
Using quadratic formula
and ![x = 0.381](https://tex.z-dn.net/?f=x%20%3D%200.381)
Answer:
Step-by-step explanation: The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Yes it can and the answer would be 0.5
Terminating decimals are numbers that never stop going after the period. Such an example would be 10/3 which would give 3.333333 indefinitely. 1/2 gives a whole number, that is, 0.5
Answer:
When doing the problem, you start with the first pair of numbers ( in this case 2,8). You go two to the right on the bottom line that says x. Then from there, you go 8 up (or y). Then, you plot your point. Do that for the rest! The first number in the pair you go right, and the second one you go up. Message me if you have any more questions!
When you divide 287 by 68, when it is not rounded, you will get 4.22058823529... (repeated decimal), but when you round it, you can either get the following: 4.22, 4.2, or 4 (choose which ever you want to pick out of these rounded forms.)
Hope this helped!
