Answer:

120

Step-by-step explanation:

The function C(n, k) can be written in terms of factorials:

C(n, k) = n!/(k!(n -k)!)

Then ...

C(16, 2) = 16!//(2!(16 -2)!) = (16·15)/(2·1)

C(16, 2) = 120

Find m< AFE and include working out.

andreyandreev [35.5K]

Answer:

∠ AFE = 80°

Step-by-step explanation:

Since BD is a straight line , then

∠ AFB + ∠ AFE + ∠ EFD = 180°, that is

50° + ∠ AFE + 50° = 180°

100° + ∠ AFE = 180° ( subtract 100° from both sides )

∠ AFE = 80°

Answer:

The result for an input of 7 is: $y=15$

The output (y-value) associated with an input of 3 is: $y=7$

Step-by-step explanation:

The image attached shown the graph for the rule $y= 2x+1$ .

In order to use the graph to predict the result for an input value of 7, you need to follow these steps:

- Draw a vertical line from $x=7$

- When the vertical line touches the graph, you must draw a horizontal line to the y-axis to find the y-value.

You can observe in the graph that the result for an input value of $x=7$ is $y=15$

Follow these steps in order to use the graph to predict the output value associated with an input value of 3:

- Draw a vertical line from $x=3$

- When the vertical line touches the graph, you must draw a horizontal line to the y-axis to find the y-value.

You can observe in the graph that the output value associated with an input value of $x=3$ is $y=7$
