Answer:11 days
Step-by-step explanation:
y =2x+1
7 divided by 3= 2 remainder 3
Don't worry about the three use the 2 times 5 to get 10.
Then 10 plus 1 to get 11. If you don't believe me then do this: 3 times 2 to get 6 then plus 1 to get 7
8y^2 + 6y + 1
List the factors of a and c.
a: 1 x 8, 2 x 4
c: 1 x 1
Since c is positive find factors from the list that will add up to the absolute value of b.
1, 1, 2, and 4 -----> (1 x 2) + (1 x 4) = 6
Arrange these four factors accordingly. Because both b and c are positive, both parentheses will have a plus sign.
( + )( + )
Ask yourself, "Which two factors with y as a variable will multiply to give me 8y^2?" Fill in the parentheses.
(4y + )(2y + )
Use trial and error(by FOILing).
(4y + 1)(2y + 1)
Check answer.
(4y)(2y) = 8y^2
(4y)(1) = 4y
(2y)(1) = 2y
(1)(1) = 1
Set up as a polynomial.
8y^2 + 4y + 2y + 1
Combine like-terms.
8y^2 + 6y + 1
So 8y^2 + 6y + 1 is equal to (4y + 1)(2y + 1).
Domain is the set of x values in which the graph of a function exists. If the domain is all real numbers; that means there are no gaps in the graph. The only time the domain is not ARN is when there is a square root, denominator, or log/ln. Anything under a square root must be positive. The denominator cannot be equal to zero. A log function must be strictly positive. Therefore all of the equations listed above apply.

Second 5.
I'm not completely sure what this is referring to (please tell me if there is another part for this because there isn't any numbers such as <1 shown on the picture.)
