Let x be the first integer, then
:
x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) = 519
:
6x + 15 = 519
:
6x = 504
:
x = 84
:
*****************************
Our sequence is
:
84, 85, 86, 87, 88, 89
:
The third integer is 86
All four angles are exterior angles of the quadrilateral.
We know that the sum of exterior angles of any polygon is 360 ° .
So we can add together the four angles and solve for x:
(x+16)+(3x-1)+6x+5x = 360
15x+15=360
15x=345
x=345/15=23 °
To find the final term to compete the square you need to divide the 'x' term by 2 then square it

- equivalent equation
The answer is y= -1
When the slope is 0, we refer to the line as a constant function. In slope intercept form, the line is equal to y = mx + b
"m" is the slope, and "b" is the y-intercept.
Let's replace those in the function.
y = 0*x - 1
0 multiplied by anything is 0
y = 0 - 1
y = -1
