There are 4 eights in a deck of cards so it would be 4 out of 52 or 4/52 = 1 out of 13
Answer: Domain (-∞,∞) ; range: (0,∞)
Step-by-step explanation:
1. The exponential functions with the form
has domain of all real numbers, becaure there is no values in the set of real number for which the value of
is not define. When
approches to ∞, the function approches to ∞.
2. When
approches to -∞, the function approches to 0 but never touches it. This means that
is always greater than zero (
). Therefore, the range of the function is (0,∞).
First thing to do is to solve each of these for y. The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3. From that you can tell the positive slopes are found in the second and third equations. Those are the ones we will test now for the point (3, -9). y=-9 and x=3, so let's fill in accordingly. The second equation filled in is -9=4(3)-21. Does the left side equal the right when we do the math? -9=12-21 and -9=-9. So the second one works. Just for the sake of completion, let's do the same with the third: -9=4(3)+21. Does -9=12+21? Of course it doesn't. Our equation is the second one above, y+9=4(x-3).

Answer: Option C. Ellipse
Step-by-step explanation:
The general equation of an ellipse has the following form:

Where the point (h, k) is the center of the ellipse
In this case we have the equation

Note that its shape matches that of a ellipse with center (9, -2)

Therefore the answer is the obtion C
