Answer:
104
Step-by-step explanation:
15 x 14= 210 divide by 2
105
180 - 105 = 75
15 + 14 + 75 = 104
Answer:
Step-by-step explanation:
Hello, please consider the following.

So this is divisible by 3.
Now, to prove that this is divisible by 9 = 3*3 we need to prove that
is divisible by 3. We will prove it by induction.
Step 1 - for n = 1
4+17=21= 3*7 this is true
Step 2 - we assume this is true for k so
is divisible by 3
and we check what happens for k+1

is divisible by 3 and
is divisible by 3, by induction hypothesis
So, the sum is divisible by 3.
Step 3 - Conclusion
We just prove that
is divisible by 3 for all positive integers n.
Thanks
Answer:
<h2>A) y= -x + 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line<em>:</em>

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

==========================================
We have the points (-1, 2) and (4, -3).
Calculate the slope:

Put the value of the slope an the coordinates of the point 9-1, 2) to the equation of a line:

<em>subtract 1 from both sides</em>

Finally:
