Answer:

2y2+9y−10

Step-by-step explanation:

Distribute the Negative Sign:

=−2y2+6y−1+−1(−4y2−3y+9)

=−2y2+6y+−1+−1(−4y2)+−1(−3y)+(−1)(9)

=−2y2+6y+−1+4y2+3y+−9

Combine Like Terms:

=−2y2+6y+−1+4y2+3y+−9

=(−2y2+4y2)+(6y+3y)+(−1+−9)

=2y2+9y+−10

Write as an expression: a number that is equal to twice as much as x
lesantik [10]

Let's call the number we're looking for y. We know that y is twice as much as x.


Twice as much as a number simply means the double of that number, and in turn the double of a number means to muliply that number by 2.


So, in order to obtain y, you have to multply x by 2. In formula, you have


y = 2\cdot x or simply y = 2x

What is the domain and range
Rainbow [258]

Well, keep in mind that the domain of a function is the entire set of possible values of the independent variable. To make it more clear, the domain is the set of all possible x-values, which will make the function work, and with real y-values as the output. So, the range would be the set of all of the second elements of an ordered pair (y-coordinates).

If you made a T chart like the picture you have above, you would have to put x (age of person) and y (books read).

So,

x = age of person

y = books read
