Answer:
4x−7
Step-by-step explanation:
Being given our polynomial:
+ x - 14,
We must find the roots to get our answer.
x = (- 1 ± √(1 - 4*4*(-14)) / 8
x = (- 1 ± √225) / 8
x = ( -1 ± 15) / 8
x₁ = (- 1 + 15)/ 8 = 14/8 = 7 / 4
x₂ = (- 1 - 15) / 8 = - 16/2 = - 8
The factors we came up with:
(x - x₁)(x - x₂)
(x - 7/4)(x + 8)
1/4(4x - 7)(x + 8)
So,
The correct option is C.

Answer:
Step-by-step explanation:
1. Substitute into first equation and solve for "x" in order to find the x-intercept of the first line:
2. Substitute into the first equation and solve for "y" in order to find the y-intercept of the first line:
Knowing that first line passes through the points and , you can graph it.
3. Substitute into second equation and solve for "x" in order to find the x-intercept:
4. Substitute into the second equation and solve for "y" in order to find the y-intercept of the second line:
Knowing that second line passes through the points and , you can graph it.
The solution of the system of equations is the point of intersection between the lines. Therefore, the solution of this system is:
Answer:
Option D is correct. All US households are among the population of interest.
Step-by-step explanation:
The Census bureau is a national body in the U.S. and they do the survey of 250000 different households monthly. The surveys go out to all corners of the U.S. depending on which part of the nation is doing the survey next.
