Answer:
.
Step-by-step explanation:
We have been given an expression and we are asked to simplify our given expression.
Using order of operations (PEMDAS) we will remove parenthesis first.
After removing parenthesis our expression will be,
After canceling out 1 with -1 we will get,
So our given expression simplifies to .
Let us write our expression in standard form. Since our expression is a polynomial and to write any polynomial in standard form, we write each term in order of degree, from highest to lowest, left to right.
Upon putting our polynomial into standard form we will get,
Therefore, after simplifying and putting our given expression in standard form we get our final expression as: .
Answer:
The first one is linear, the second one is not.
Step-by-step explanation:
Look at the y- axis side, and you can see that the number on the linear one jump up with an even 9. But, the non linear one jupms up by a whole bunch and some by not a lot, therefore making it nonlinear. I hope this helps :)
Answer:
The correct answer is 48, given by option c.
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
Positive correlation means that the variables are directly proportional, and thus, we apply cross multiplication.
If v is 24 when u is 10, which of these is most likely to be the value of v when u is 20?
24 - 10
x - 20
Applying cross multiplication:
Simplifying both sides by 10:
The correct answer is 48, given by option c.
