Your answer would be C and D, the domain for this function is all real numbers, and the range for this function is the set {-5}.
C is correct: The domain of a function is the amount of x values. For example, if you had a line going from an x value of 1 to an x value of 3, the domain would be {1<x<3}.
In this case, C is stating the domain of this function is all real numbers. This is true, because the straight line will continue for all values of x, so therefore the domain is all values of x, or all real numbers.
D is correct: The range is the exact opposite of a domain of a function. It is the number of y values the function covers.
In this case, D is stating the range is {-5}. This is correct, because the straight line only covers the y value of -5, so therefore that is the range.
A is therefore incorrect because the domain has already been established as all real numbers. B is incorrect because a horizontal line is a function, and one value of y can have multiple values of x. E is incorrect because the range has already been established as only one number.
Good luck!
Answer:
4 ÷ 10
Step-by-step explanation:
The computation of P is shown below:
If we add two marbles i.e.
= 4 + 6
= 10 marbles
Now if we draw the second marble
P(blue) = Blue marbles ÷ total marbles
= 4 ÷ 10
In the other case
P( blue second given a green first) = 4 ÷ 10
Answer: " y = 21 " .
____________________________________________
Cross multiply:
______________________________
(2y)(4) = 7(y + 3) ;
8y = 7y + 21
Subtract 7y from each side of the equation;
8y - 7y = 7y + 21 - 7y ;
y = 21 .

Answer:
the store offered the better deal
Step-by-step explanation:
the store was only 20 dollars and online e was 42 so the store had the better deal
I believe the answer is 9
This is because in order to take out a three, There would need to be 2 3's and 9 is 3x3, so the answer is 9.
