Step-by-step explanation:

800 + 500 + 1000 + 100 + 100 =total amount of houses sold

= 2500 houses

Houses sold in Stamford + houses sold in Morristown = 800+500

= 1300

1300/2500 = 13/25 = 52/100

therefore the percentage is 52%

How do i complete the square for this equation ? x^2+ 8x+y^2-2y=64

liraira [26]

<span>Simplifying x2 + 8x + y2 + -2y = 64
Reorder the terms: 8x + x2 + -2y + y2 = 64 Solving 8x + x2 + -2y + y2 = 64 Solving for variable 'x'.
Reorder the terms: -64 + 8x + x2 + -2y + y2 = 64 + -64
Combine like terms: 64 + -64 = 0 -64 + 8x + x2 + -2y + y2 = 0

The solution to this equation could not be determined.</span>

Answer:

zeros: x = -3, -1, +2.
end behavior: as x approaches -∞, f(x) approaches -∞.

Step-by-step explanation:

I like to use a graphing calculator for finding the zeros of higher order polynomials. The attachment shows them to be at x = -3, -1, +2.

The zeros can also be found by trial and error, trying the choices offered by the rational root theorem: ±1, ±2, ±3, ±6. It is easiest to try ±1. Doing so shows that -1 is a root, and the residual quadratic is ...

x² +x -6

which factors as (x -2)(x +3), so telling you the remaining roots are -3 and +2.

For any odd-degree polynomial with a positive leading coefficient, the sign of the function will match the sign of x when the magnitude of x gets large. Thus as x approaches negative infinity, so does f(x).
