Firstly try to find the number between 100 and 400 which are actually divisible by 13 so
104,117,130………. 390
If you see the above arrangement the difference between numbers are common so we can apply arithmetic progression.
By arithmetic progression, last term can be denoted by
l= a+(n-1)d
Where l=390
a=104
d=13
n=?
390=104+(n-1)13
13n=286+13
n= 299/13
n= 23
So total number of terms =23
By using arithmetic progression sum of all A.P terms = (n/2)(a+l)
Sum = (23/2)(104+390)
=(23/2)*(494)
= 5,681
So answers is 5,681.
Answer:
23 - ( 9 - 5 )²
= 23 - (4 )²
= 23 - 16
= 7

Answer:
y = 7x - 17
Step-by-step explanation:
If you graph the coordinate (3,4) and then apply the slope (7 up / 1 down) , you will end up passing through the point (0,-17) on the y line. The point the line passes on the y line would be the y intercept.
Once you have all the necessary information, you put it into a y=mx+b form. m being the rate or slope, and b being the y-intercept.
