Answer:
D
Step-by-step explanation:
A function is where each input (here, the input is x) corresponds to exactly one output (here, the output is y). In other words, if a function is graphed, we should be able to draw a vertical line through every single part of it that will intersect it at only one place.
Let's examine each choice.
(A) Well, if we draw a vertical line through the graph, it will obviously intersect the entire line - which is an infinite number of intersections, so this is not a function.
(B) If we draw a vertical line through the portion of the graph that lies near the positive x-axis, we note that it will intersect twice, so this is not a function.
(C) If we strategically draw a vertical line through the y-axis, we see it will intersect two times, so this is not a function.
(D) We can draw a vertical line through any portion of this graph and know that it will only intersect once.
Therefore, the answer is D.
A. -6/7
Because:
(2,6) (8,-1)
(x1,y1) (x2,y2)
x1 = 2. Y1=6. X2=8. Y2= -1.
Equation for slope is m = y2-y1
x2-x1
-1-6 = -7
8-2=6
11.390.625 Because You Multiple 15 6 Times
For this case we must solve the following system of equations:
We clear x of both equations:
We match:
We find the value of "x":
Thus, the solution of the system is:
Answer:
We know that
<span>In a right triangle
if A and B are complementary angles
cos A=sin B
therefore
if cos A=5/13
then sin B=5/13
the answer is
sin B=5/13</span>
